What’s the Difference Between FHO and THR?

Femoral Head Ostectomy (FHO) and Total Hip Replacement (THR) are two surgeries used to treat severe hip problems in dogs, but they work in very different ways.

FHO involves removing the femoral head, the ball part of the hip joint. After removal, the body forms a fibrous false joint made of soft tissue. This structure cushions the joint and allows pain-free movement, though some function may be reduced.

In contrast, THR replaces both the femoral head and the socket with artificial implants, creating a new, smooth joint surface. This restores full joint structure and offers more natural motion, especially in large or active dogs.

FHO is simpler and less expensive but may not offer the same range of motion. THR gives better joint function but is more complex and costly, requiring careful case selection and recovery.

Which Dogs Are Best Suited for Each Surgery?

Femoral Head Ostectomy (FHO) and Total Hip Replacement (THR) are selected based on a dog’s size, age, and activity level.

FHO is generally better for small to medium-sized dogs, usually under 20–25 kg (45–55 lbs). These dogs often adapt well to the false joint formed after surgery. FHO is also used in cases where cost is a concern or when other health issues make THR too risky.

THR is ideal for larger dogs or highly active breeds, especially those who need full joint function for work, running, or athletic play. It offers more natural movement and strength.

Age is another factor. THR requires skeletal maturity, usually around 10–12 months old, to ensure stable implant placement. FHO can be performed at younger ages in some cases.

Lifestyle also plays a role. FHO suits lower-energy dogs or those with mild muscle loss. THR is better for dogs expected to return to high activity. Your vet will assess your dog’s build, age, and daily function to guide the best surgical choice.

Comparing Surgery Risks and Complexity

FHO and THR differ in complexity and risk, and choosing the right one involves understanding what each surgery requires.

• FHO is considered a less invasive and technically simpler procedure. It involves removing the femoral head without entering the joint capsule deeply. Complications are rare, and recovery is usually straightforward in smaller dogs.
• THR, on the other hand, is a more advanced surgery. It requires specialized implants, precise bone cuts, and careful placement of both the socket and ball components. This surgery takes longer, needs a highly trained surgeon, and carries greater risks—especially related to anesthesia, infection, and implant complications.

Despite these risks, THR is often preferred when joint function must be fully restored, such as in large breeds with severe arthritis or dysplasia. FHO may be favored for dogs with medical concerns, budget limits, or when joint damage is not extensive.

Your vet or surgeon will weigh these factors—including recovery potential and long-term goals—before recommending the most suitable approach.

Cost Comparison: FHO vs. THR

The cost of FHO and THR can vary based on your location, the veterinary surgeon’s expertise, and your dog’s specific case.

• FHO surgery typically costs $1,000 to $2,500. This often includes pre-op bloodwork, surgery, pain meds, and follow-up care.
• THR is more expensive, ranging from $4,000 to $8,000 per hip, depending on implant type and facility. It also covers X-rays, advanced anesthesia, implant materials, surgical fees, and longer post-op monitoring.

FHO has a lower upfront cost and fewer material needs, making it more accessible for many dog owners. However, THR may offer better long-term function, especially in large or active dogs—possibly reducing future rehab costs or mobility issues.

It’s important to consider both short-term affordability and long-term quality of life. While THR is more expensive, the improved comfort and mobility may justify the higher cost in many cases. Your vet will help break down what's included in the estimate so you can make an informed decision.

Recovery Time and Rehabilitation Needs

Both FHO and THR require careful recovery, but the timelines and expectations differ.

• FHO recovery is typically shorter. Dogs often begin weight-bearing within a few days to 1 week, and most regain good walking ability by 4–6 weeks. Physical therapy is key to rebuilding strength and balance. Exercises start slowly and progress over 6–12 weeks.
• THR recovery takes longer and is more structured. Dogs are usually confined to limited movement for 6–8 weeks, with leash walks and controlled rehab. Physical therapy focuses on restoring range of motion, balance, and joint use. Full recovery can take 12–16 weeks or longer.

In both cases, post-op care includes pain control, anti-inflammatory meds, suture removal, and vet follow-ups. Jumping, running, and rough play are restricted during early healing.

THR requires more frequent rechecks to monitor implant placement. FHO patients benefit from consistent at-home exercises and hydrotherapy. While both procedures lead to good outcomes, success depends heavily on owner compliance with rehab and post-op instructions.

Long-Term Outcomes: What to Expect

Both FHO and THR offer good long-term results, but they differ in joint function and comfort over time.

• FHO creates a fibrous false joint. Dogs typically regain strong mobility and pain relief, though a slight limp or reduced range of motion may persist. Most small to medium-sized dogs do very well, especially with early physical therapy. Muscle tone often returns gradually, though some asymmetry may remain.
• THR offers the most natural joint function, especially in larger breeds. Dogs usually regain a smooth gait, full leg use, and a higher level of physical activity. Once fully healed, many dogs return to running, swimming, and even agility work with no visible lameness.

Both procedures dramatically improve quality of life for dogs suffering from hip pain. Reported satisfaction is high among owners for both surgeries when post-op care is followed closely.

Overall, THR provides superior function but requires more investment. FHO is a reliable alternative with fewer resources needed—especially for dogs not demanding peak performance.

Potential Complications to Watch For

Each surgery has its own set of possible complications, though most dogs recover well when care is properly managed.

FHO complications may include:

• Persistent or returning pain
• Limb shortening causing mild gait changes
• Weakness or instability in the operated leg
• Delayed or incomplete muscle regrowth

These are more likely in large dogs or those who skip rehab.

THR complications can be more serious, including:

• Implant dislocation if the joint isn’t protected during healing
• Infection, which may require implant removal
• Loosening or wear of the implant over time
• Nerve injury during the procedure (rare)

Strict post-op restrictions help avoid most issues. THR requires more frequent checkups to monitor implant stability, especially in active dogs.

In both surgeries, careful follow-up, pain management, and rehab are key to preventing problems. If signs like swelling, limping, or reluctance to use the leg return, prompt veterinary attention is needed.

Making the Right Choice for Your Dog

Choosing between FHO and THR depends on your dog’s size, lifestyle, pain level, and your resources. Here’s a simple way to look at it:

• FHO is practical for small to medium-sized dogs, dogs with lower activity needs, or owners seeking a more affordable and lower-risk solution. It offers good pain relief and function, especially with early rehab.
• THR is ideal for larger, active dogs or those needing more complete joint restoration. It provides a smooth, stable joint and excellent mobility but requires more aftercare and cost.

Questions to discuss with your vet:

• Is my dog a candidate for THR based on size and health?
• How severe is the hip damage, and can FHO provide enough relief?
• What post-op care and rehab will be required in each case?
• Are there any risks based on my dog’s age or condition?

A thoughtful discussion with your veterinary surgeon ensures the best outcome for your dog’s comfort and mobility.

FAQs

Is FHO or THR better for large dogs?

Total Hip Replacement (THR) is generally the better option for large dogs. It restores full joint function, offers better limb alignment, and reduces long-term joint stress. While some large dogs do well with FHO, they may have ongoing weakness or limping due to the false joint. THR provides more stable, pain-free movement and is often recommended when size and activity demands are high.

Can my dog walk normally after FHO?

Yes, many dogs walk normally after Femoral Head Ostectomy (FHO), especially smaller breeds. While some dogs may have a slight limp or reduced range of motion, most regain strong walking ability and are pain-free. With proper rehab, muscle strength improves and compensates for the missing joint, allowing dogs to walk, run, and play comfortably in daily life.

How long does it take to recover from THR?

Recovery from Total Hip Replacement typically takes 12 to 16 weeks. Dogs are kept on restricted activity for the first 6–8 weeks, followed by gradual rehab. Physical therapy, controlled leash walks, and regular vet checks help ensure proper healing. Most dogs return to full activity and comfort by 4 months, though some may need longer based on age or fitness.

Is FHO painful for dogs long-term?

FHO usually provides long-lasting pain relief, especially when performed early and followed by rehab. Some dogs may experience minor discomfort or muscle imbalance long-term, especially large breeds. However, most dogs don’t show signs of pain and adjust well to the false joint. Consistent exercise, healthy weight, and muscle support help maintain comfort over time.

What happens if I can’t afford THR?

If THR is not affordable, FHO is a reliable alternative—especially for small or medium dogs. It’s less expensive and still offers pain relief and good mobility when combined with rehab. In some cases, conservative management (like weight control, joint supplements, and physical therapy) may help delay surgery. Your vet can guide you on the best budget-friendly plan for your dog’s needs.

Can a failed FHO be corrected with THR later?

Yes, Total Hip Replacement can be performed after a failed FHO, though the surgery is more complex. Scar tissue, bone changes, or muscle atrophy from the earlier procedure may affect implant placement. Still, experienced surgeons can often restore function and comfort with THR. If FHO doesn’t relieve pain or causes long-term issues, THR may be a viable second option.

‍

Does FHO Surgery Improve a Dog’s Long-Term Quality of Life?

• Pain reduction over time
  Most dogs experience steady pain relief as healing progresses. The removal of the femoral head eliminates bone-on-bone contact, which greatly reduces chronic discomfort.
• Overall comfort in daily activities
  Dogs typically return to normal or near-normal activity levels after recovery. They walk, run, and play comfortably, especially when rehab exercises are followed properly.
• Owner satisfaction reports
  Studies show that 83–96% of dog owners report positive long-term outcomes after FHO surgery. This includes restored mobility, better temperament, and improved energy levels.

Over time, dogs regain function in the affected limb and adapt well to the “false joint.” While minor gait changes can remain, they usually don’t affect the dog’s comfort or activity. With proper care, most dogs enjoy a pain-free life and stay active for years after FHO.

How Well Do Dogs Walk After FHO Surgery?

Most dogs walk well after FHO surgery, especially once the healing process is complete.

• Gait returns to near-normal: Within a few weeks, many dogs start walking and even trotting with minimal signs of discomfort.
• Mild limps or bunny-hopping may appear: Some dogs develop minor adaptations like a mechanical limp or occasional bunny-hopping, especially during fast movement. These don’t usually affect daily function.
• Recovery timeline: Most dogs begin bearing weight in 1–2 weeks. Comfortable walking is often seen by 4–6 weeks, with near-full recovery taking 3–6 months.

Smaller breeds often recover faster and with fewer visible changes. For larger dogs, it might take more time and support. Still, pain reduction is quick, and quality of life improves significantly after surgery. Owners often report their dogs appear more active and willing to move shortly after the initial recovery period.

What Physical Changes Might Persist After Surgery?

After FHO, some physical changes can remain long-term, even with good recovery.

• Muscle atrophy: The thigh and hip muscles may shrink due to pre-surgical limping or disuse. While rehab helps, full muscle mass may not return.
• Leg shortening: Removing the femoral head can cause the surgical limb to appear slightly shorter. This usually doesn’t affect mobility.
• Decreased range of motion: Without a true joint, hip flexibility may be reduced. Dogs compensate well, but some stiffness might stay.
• Weight-bearing ability: While walking may look normal, some dogs shift more weight to the opposite leg when standing still.

These changes are often mild and don’t limit function. Most dogs adapt fully, especially if they’re active and supported with good rehab. Long-term comfort remains excellent despite these small structural differences.

What Kind of Joint Forms After FHO Surgery?

FHO creates a fibrous pseudo-joint in place of the natural hip joint.

Once the femoral head is removed, no bony connection remains between the femur and pelvis. Instead, the body forms a soft tissue capsule filled with fibrous tissue. This tissue cushions the joint, allowing smooth, pain-free movement.

Though not a real joint, the pseudo-joint acts as a shock absorber. It molds to the dog’s motion patterns over time. This adaptability supports walking, running, and even playful activity in most dogs.

The joint’s long-term durability is excellent, especially when weight is controlled and rehab is consistent. While large dogs might show slight instability or reduced motion, the fibrous joint holds up well in the long run.

What Factors Affect Long-Term Outcomes?

Several things impact how well a dog recovers after FHO:

• Dog’s size and body weight: Smaller dogs tend to recover better. Larger breeds may need longer rehab and may show more noticeable gait changes.
• Chronic vs acute hip issues: Dogs with long-standing arthritis or hip dysplasia may have more muscle loss before surgery, affecting results. Dogs with recent trauma often do better.
• Surgical alternatives: In some cases, especially in large or active dogs, total hip replacement (THR) may offer smoother motion and a more natural gait. Still, FHO remains a great option when cost or health limitations rule out THR.

In general, FHO provides excellent comfort and good function in most dogs. The key is matching the procedure to the dog’s size, health, and activity level.

Role of Rehab in Long-Term Success

Rehabilitation is one of the most important parts of FHO recovery.

• Start early: Light rehab usually begins within a few days post-surgery to maintain joint motion and avoid muscle loss.
• Hydrotherapy is very effective: Water-based exercises help build strength without stressing the joint.
• Rehab duration varies: Some dogs may need a few weeks, while older or larger dogs benefit from longer therapy plans.

Exercises like leash walks, sit-to-stand drills, and gentle hill work can be added as healing progresses. Rehab not only improves muscle strength but also teaches the dog to use the leg properly again. Follow-ups with your vet or a certified canine rehab specialist ensure the exercises are working. A strong rehab plan often makes the difference between average and excellent outcomes.

Final Thoughts: Is FHO a Reliable Long-Term Option?

FHO is a reliable and proven surgery, especially for:

• Small to medium-sized dogs
• Dogs with hip injuries, fractures, or chronic joint pain
• Cases where cost or health limits more advanced surgery like THR

While some changes in gait or muscle tone may remain, dogs usually regain full function. Most live pain-free, active lives with no ongoing medication or surgery needed. Larger dogs can still do well with FHO, but their success depends heavily on proper rehab and weight control.

Your vet will help determine if FHO is right for your dog. When combined with thoughtful aftercare and consistent support, it offers lasting relief and good quality of life for years to come.

FAQs

Can dogs live a normal life after FHO surgery?

Yes, most dogs live a very normal and active life after FHO surgery. Once healed, they can walk, run, and play comfortably. Some dogs may have a slight limp or reduced range of motion, but these issues rarely affect their quality of life. With good rehab and proper care, long-term pain relief and function are excellent, especially in small to medium-sized dogs.

How long does it take for a dog to fully recover from FHO?

Full recovery typically takes 3 to 6 months. Most dogs begin bearing weight within 1 to 2 weeks and walk comfortably by 4 to 6 weeks. Rehab speeds up the healing process and helps rebuild lost muscle. Even after reaching full function, some dogs may continue to improve in strength and coordination over time with continued activity and exercise.

Will my dog limp permanently after FHO?

Some dogs may have a mild limp that shows up when they’re tired or moving quickly, but it’s usually not permanent or painful. In many cases, the limp fades over time with rehab and strengthening. Even if a minor limp remains, most dogs don’t show signs of discomfort and can live a very active, happy life.

Is FHO surgery effective in large breeds long-term?

FHO can work in large dogs, but results vary more than in smaller breeds. Success depends on factors like body weight, muscle condition, and rehab effort. Large dogs may retain a noticeable gait change or reduced strength, but many still do well. For very active or working dogs, total hip replacement may offer better function in the long term.

What is a false joint, and does it last?

A false joint, or pseudo-joint, is a fibrous capsule that forms after the femoral head is removed. It’s not made of bone or cartilage but allows smooth, cushioned movement. This structure holds up well over time and provides lasting pain relief. While it doesn’t restore full range of motion, it typically allows good mobility for life.

Does physiotherapy really make a difference long-term?

Yes, physiotherapy has a major impact on long-term success. It helps restore muscle strength, improve joint motion, and teach your dog to use the leg properly again. Dogs who receive structured rehab often recover faster and show better function long-term. Skipping rehab can lead to stiffness, weakness, and less complete recovery.

‍

What Is FHO Surgery and Why It's Done

Femoral Head Ostectomy (FHO) is a surgical procedure where the femoral head and neck are removed to relieve hip joint pain. It’s often used in small to medium-sized dogs when the hip joint is damaged by trauma, arthritis, or diseases like Legg-Calvé-Perthes.

• Why vets recommend FHO: It’s less invasive and more affordable than total hip replacement.
• Best for dogs under 50 lbs: These dogs form a functional “false joint” from scar tissue more easily.
• When it’s preferred: In cases where bone quality is poor, cost is a concern, or total hip replacement isn’t feasible.

After surgery, a fibrous tissue capsule forms in place of the removed joint. This “false joint” lets dogs walk without bone-on-bone contact. The success of FHO depends heavily on post-surgical care, including early movement, physical therapy, and weight management. When done in the right patient, this procedure helps restore pain-free movement and a good quality of life.

How Successful Is FHO Surgery in Dogs?

FHO surgery has a high success rate, especially in smaller dogs. Studies and owner feedback show strong outcomes.

• Owner satisfaction: Around 93–96% of pet owners report improved quality of life.
• Clinical outcomes: Most dogs regain near-normal mobility with minimal pain.
• Short-term recovery: Dogs may limp or have muscle loss early on but show clear improvement by 4–6 weeks.
• Long-term results: With rehab, most dogs can run, jump, and even hike.

Dogs who receive proper rehab therapy and have good muscle condition before surgery tend to do better. Vets see fewer complications and faster recovery in these dogs. The most important factor? Post-op care at home. With cage rest early on, followed by active physical therapy, most dogs regain strength and mobility. Even dogs with prior pain and stiffness often return to playful, active lives after full recovery.

Factors That Influence Success Rate

FHO outcomes depend on several key factors that dog owners and vets must consider.

• Dog’s size and weight: Small to medium dogs (<50 lbs) do best.
• Muscle strength: Pre-surgery conditioning helps with post-op recovery.
• Weight management: Obese dogs may recover slower and with more complications.
• Timely surgery: Delayed treatment can lead to more muscle loss.

Surgical skill and proper technique matter, too. But even with excellent surgery, poor aftercare can affect healing. That’s why owners must follow rehab plans closely. Dogs kept active before surgery tend to form stronger “false joints” and recover faster. Dogs with severe muscle wasting or untreated hip pain for long periods may struggle more with post-op mobility.

FHO is not a magic fix—it’s a team effort between vet and owner. With proper planning and care, though, the success rate is high, and the benefits are long-lasting.

Recovery Timeline and What to Expect

The healing process happens in stages and varies by dog, but most follow a general timeline.

• Day 1–3: Crate rest, pain meds, and short leash potty breaks only.
• Week 1–2: Passive range-of-motion exercises and short walks begin.
• Week 3–6: Walking improves; light exercises increase gradually.
• Week 6–12: Full muscle recovery and normal activity returns.

Dogs usually start weight-bearing within a week, though limping is common. Rehab exercises help rebuild muscle strength. Hydrotherapy, leash walking on inclines, and sit-to-stand drills are often used.

It’s important to monitor your dog’s pain levels and mobility each week. Swelling or lameness that worsens should be reported to your vet. By 3 months, many dogs resume near-normal movement, though some may retain a slight limp. Don’t rush the process. A slow, steady recovery gives the best long-term results.

Possible Long-Term Complications

While FHO is generally successful, there can be long-term issues in some dogs.

• Limb shortening: A minor leg length difference is common but usually not limiting.
• Gait changes: Some dogs have a permanent limp or altered stride.
• Reduced hip motion: Range of motion may not fully return in all cases.
• Muscle atrophy: Can occur if physical therapy is skipped or limited.

Most of these issues don’t impact quality of life significantly, but they can affect athletic performance in working or very active dogs. These risks are lower in smaller dogs and those who stick to rehab programs. Owners should stay in touch with their vet and schedule check-ups during the recovery period to detect any concerns early.

Bilateral FHO: What If Both Hips Are Affected?

Dogs with problems in both hips can still benefit from FHO—sometimes on both sides.

• One side at a time: Vets usually recommend staging surgeries.
• Quality of life: Most dogs return to normal walking after both hips heal.
• Research support: Studies show high success in bilateral cases.

Rehab is even more critical when both hips are involved. Dogs need help with balance and coordination during recovery. Use of slings or harnesses indoors and careful progress with leash walking helps prevent injury or overuse. With time and support, many dogs with bilateral FHO can run, play, and live happily pain-free.

When Is FHO the Best Option?

FHO is often chosen when other treatments aren’t suitable or accessible.

• Compared to total hip replacement: FHO is more affordable and less invasive.
• Best choice for: Smaller dogs, those with poor bone health, or those not suited for implants.
• When owners can’t afford implants: FHO is a reliable “salvage” procedure.

It’s not ideal for large-breed dogs or those needing high-performance mobility, like working dogs. However, for family pets with chronic hip pain and limited function, FHO can restore comfort and ease of movement. It’s especially helpful for younger dogs with trauma and seniors who can’t tolerate complex surgeries.

‍

FAQs

Is FHO surgery painful for dogs?

Yes, like any surgery, FHO can cause pain at first. However, your vet will prescribe pain medications to manage it during the early days. Most dogs show reduced discomfort within a few days. As healing progresses, pain decreases, and the dog often becomes more active. The long-term goal is to eliminate chronic hip pain caused by the original condition.

Can large breed dogs have a successful FHO?

Large dogs can have successful outcomes, but results are less predictable than in smaller dogs. They may retain a limp or limited range of motion. With strong muscles and proper rehab, some large dogs still regain good function. In general, total hip replacement is often preferred for larger breeds if it's financially and medically possible.

How long before my dog can walk after FHO?

Most dogs begin to bear weight within 3–7 days after surgery. At first, the walk may be wobbly or limping. With gentle rehab, walking improves each week. By 4–6 weeks, dogs typically walk more normally. Full recovery, including muscle rebuilding and pain relief, usually takes about 8–12 weeks.

What are signs the surgery didn’t work well?

Signs of poor recovery include persistent lameness, unwillingness to walk, pain when touching the hip, or muscle wasting over time. These may suggest complications like scar tissue problems or inadequate rehab. If you notice these, consult your vet immediately for re-evaluation and possible therapy adjustments.

Does FHO affect lifespan or activity levels?

FHO does not shorten your dog’s lifespan. With proper care, most dogs return to normal or near-normal activity levels. They can run, play, and live comfortably. Some may have a mild limp, but this usually doesn’t affect their happiness or quality of life. Long walks and active play are still possible after recovery.

Is physical therapy necessary after FHO?

Yes, physical therapy is very important for success. It helps rebuild muscle strength, improves range of motion, and speeds up recovery. Rehab exercises like leash walks, sit-to-stand drills, or hydrotherapy make a big difference. Without it, your dog may limp longer or never fully regain function. Always follow your vet’s rehab plan.

‍

What to Expect After FHO Surgery

Understanding what happens after Femoral Head Ostectomy (FHO) helps you prepare for each stage of your dog’s recovery.

• First 1–2 days: Your dog may feel drowsy due to anesthesia. Pain medication and strict rest are essential during this time.
• Week 1–2: You may notice some swelling or bruising near the surgical area. Your dog might begin light toe-touching or brief weight-bearing on the leg.
• Week 3–6: Controlled rehab begins. This includes slow leash walks and light physical therapy to rebuild muscle and range of motion.
• Week 7–12: Most dogs regain normal function by this stage. Some may still have minor stiffness or muscle loss that improves with ongoing activity.

The goal of post-op care is to support healing, reduce pain, and restore function. With your help, proper rest, gradual exercise, and vet check-ups, your dog can return to a comfortable, active life.

Immediate Post-Surgery Care (Days 1–3)

The first few days after FHO surgery are critical for setting the stage for healing. This period focuses on pain control, limiting movement, and protecting the surgical site.

• Crate rest and safe confinement: Keep your dog in a small, quiet space like a crate or pen. This helps avoid sudden movements that may stress the healing leg.
• Leashed potty breaks only: Take your dog outside on a leash for bathroom needs. Avoid stairs, running, or jumping.
• Using ice therapy: Apply a cold pack (wrapped in a towel) over the surgical site for 10–15 minutes, 2–3 times daily. This reduces swelling and discomfort.
• Starting passive range-of-motion exercises: Your vet may show you how to gently move the leg to keep the joint flexible. Do this only if approved.
• Preventing licking or chewing: Use an E-collar or recovery sleeve to protect the incision from infection.
• Giving prescribed meds: Administer all pain medications and antibiotics exactly as directed by your veterinarian.

This stage is all about keeping your dog comfortable, minimizing movement, and preventing complications. Follow your vet’s instructions closely to avoid setbacks and support a smooth recovery. Consistency in care here makes a big difference later.

Caring for the Incision Site

In the first two weeks after FHO surgery, taking care of the incision is crucial for preventing infection and promoting healing.

• How often to check the wound: Inspect the incision 1–2 times daily for redness, swelling, or discharge.
• Signs of infection to watch for: Look out for pus, foul smell, increased redness, or warmth around the incision. If your dog licks the area excessively or seems in pain, contact your vet.
• Keeping the incision clean and dry: Do not apply creams or sprays unless your vet advises. Avoid letting the incision get wet or dirty—this includes keeping your dog away from muddy areas or damp grass.
• Bathing restrictions and suture removal timing: Do not bathe your dog until the sutures are removed or the incision is fully healed—typically 10–14 days after surgery. Your vet will advise if staples or stitches need removal.

Keep your dog’s environment clean and calm. Prevent licking with an E-collar or soft recovery cone. With good wound care, you reduce the chance of infection and help your dog heal faster.

Early Rehab Tips (Days 4–14)

This phase introduces gentle movement to prevent stiffness and starts building comfort with basic activity.

• Warm compresses and massage: Apply a warm compress (not hot) for 10 minutes before massage. Gently massage muscles around the hip to improve blood flow and reduce tension.
• Gradual leash walking routine: Begin with 5-minute walks on flat surfaces 2–3 times a day. Use a short leash and walk slowly.
• Supporting with sling/harness indoors: For dogs with weak hind limbs, a rear-support sling or towel under the hips helps reduce strain.
• Encouraging calm behavior while healing: Limit excitement and prevent jumping or rough play. Use food puzzles and chews to keep your dog mentally stimulated while physically resting.

These small steps set the foundation for long-term healing. Always follow your vet’s rehab plan and observe how your dog responds to gentle movement.

Strength-Building and Exercise (Weeks 2–6)

As healing progresses, the focus shifts to rebuilding strength and range of motion in the hip and leg.

• Sit-to-stand drills and wall sits: Encourage your dog to sit and stand slowly, 5–10 times in a row. Use a wall to support the healthy side during “wall sits.”
• Walking up inclines and gentle ramps: Start with low slopes or shallow ramps to engage the hip joint without stress.
• Controlled leash walks: how to progress safely: Increase walk time by 5 minutes each week if no limping occurs. Avoid slippery or uneven surfaces.
• Hydrotherapy and swimming introduction: Swimming is a low-impact way to rebuild muscles. Use a life vest and only in vet-approved, clean water environments.
• Using ice after exercise: Apply ice for 10–15 minutes on the hip after exercise sessions to reduce inflammation.

This stage helps restore normal movement. Track progress daily and adjust activities if soreness or fatigue appears.

Monitoring Healing and When to Call the Vet

Ongoing monitoring helps catch issues early and ensures your dog stays on track with recovery.

• Follow-up exam timing: Most vets schedule a recheck around 2 weeks post-surgery, then again at 6–8 weeks.
• What is normal vs. warning signs: Mild swelling, slight limping, or low activity is common. Warning signs include severe limping, refusal to walk, or signs of pain when touched.
• Dealing with swelling, bruising, or seroma: Minor swelling or fluid buildup (seroma) is usually not serious. If the area gets warm or painful, call your vet.
• When rehab support is needed: If your dog struggles with exercises or limping worsens, seek help from a vet or certified canine rehab therapist.

Don’t ignore small changes—early action prevents long-term issues. Regular updates with your vet ensure recovery stays on track.

Full Recovery Expectations (Weeks 6–12)

This is the final stretch of recovery, where your dog regains most strength and returns to normal routines.

• Signs your dog is ready for more activity: You’ll notice improved weight-bearing, stronger muscles, and eagerness to move without limping.
• Reintroducing normal play and routines: Start short play sessions and allow off-leash activity in a safe area. Avoid high-impact jumps until cleared by your vet.
• Final vet check and long-term outcomes: A final evaluation around 10–12 weeks ensures the joint has healed well. X-rays may be taken to assess progress.
• Tips for maintaining joint health after recovery:
  
  • Keep your dog at a healthy weight
  • Provide joint supplements if recommended
  • Stick to a regular low-impact exercise routine

Most dogs enjoy a pain-free, active life after FHO. Stay consistent with care and your dog will likely return to doing the things they love.

FAQs

How long should I restrict my dog after FHO surgery?

Activity should be restricted for at least 6–8 weeks after FHO surgery. Crate rest and controlled leash walks are important during the early healing phase. Your vet will guide you on when to slowly increase activity. Full recovery can take up to 12 weeks, depending on your dog’s progress and comfort level.

What are the best rehab exercises after FHO?

Start with gentle leash walking and passive range-of-motion stretches. As healing progresses, add sit-to-stand drills, incline walking, and later hydrotherapy. Each exercise should be done slowly and carefully. Always follow your vet’s or rehab therapist’s guidance to prevent overuse and promote proper muscle rebuilding.

Can my dog go upstairs during recovery?

No, stairs should be avoided during the first few weeks. They can strain healing muscles and joints. If stairs are unavoidable, use a sling or harness to support your dog. Once your vet approves, short stair use with supervision may be allowed around weeks 4–6 of recovery.

When is hydrotherapy safe to start?

Hydrotherapy can usually begin around week 2 or 3, once the incision is fully healed. It’s a low-impact way to build strength and improve movement. Always get your vet’s approval before starting, and ensure sessions are guided by trained professionals for best results.

What if my dog still limps weeks after surgery?

Some limping is normal in the early stages, especially if your dog hasn’t regained full muscle strength. But if limping continues beyond 6–8 weeks or worsens, consult your vet. It may signal delayed healing, discomfort, or the need for adjusted rehabilitation exercises.

Is it normal for the incision to look bruised?

Yes, mild bruising or slight swelling around the incision is common during the first few days. It should gradually improve. However, if the area becomes red, warm, painful, or oozes pus, contact your vet immediately as these may be signs of infection.

‍

Femoral Head Ostectomy (FHO) is a surgery performed to relieve severe hip pain in dogs by removing the damaged head and neck of the thigh bone. This procedure stops painful bone-on-bone contact and allows the formation of a “false joint,” helping dogs move more comfortably.

Understanding the recovery process after FHO surgery is important for dog owners. Recovery involves rest, pain management, and physical therapy, all crucial to help your dog regain strength and mobility. Knowing what to expect helps you provide better care and support during healing.

Being prepared for the recovery timeline, activity restrictions, and signs to watch for ensures your dog has the best chance for a smooth, successful recovery. This knowledge also reduces stress for both you and your dog, improving overall comfort and quality of life after surgery.

Hospital Stay and Immediate Care

After Femoral Head Ostectomy (FHO) surgery, most dogs stay in the hospital for one to two days. This allows veterinarians to monitor your dog closely as they wake up from anesthesia and manage any immediate post-surgery needs.

• Length of stay: The hospital stay usually lasts 24 to 48 hours, depending on your dog’s condition and how well they recover from anesthesia.
• Pain management: Vets provide pain relief through medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and opioids if needed. Managing pain early is essential to keep your dog comfortable and encourage gentle movement.
• Medications: Your dog may also receive antibiotics to prevent infection and muscle relaxants to ease stiffness.
• Protecting the incision: To stop your dog from licking or biting the surgical site, an Elizabethan collar (cone) or alternative protective device is used. This prevents infection and helps the wound heal properly.

Close monitoring and early pain control during the hospital stay set the stage for a smoother, less painful recovery once your dog returns home.

Post-Surgery Care at Home

After Femoral Head Ostectomy (FHO) surgery, restricted activity and cage rest are vital to ensure proper healing. Limiting your dog’s movement helps prevent strain on the surgical site and reduces the risk of complications.

• Restricted activity: Keep your dog confined to a small, quiet space or crate to avoid jumping, running, or climbing stairs for at least 6 to 8 weeks. Use a leash for short bathroom breaks only.
• Wound care: Keep the surgical incision clean and dry. Avoid bathing your dog until the vet says it’s safe. If cleaning is needed, use mild antiseptic solutions as directed by your vet, and never apply harsh chemicals.
• Watch for signs: Check the incision daily for swelling, bruising, redness, discharge, or a foul odor. Some bruising and mild swelling are normal, but worsening symptoms may indicate infection.
• Prevent licking: Use an Elizabethan collar (cone) to stop your dog from licking or biting the wound, which can cause infection and delay healing.

Careful attention to post-surgery care supports healing and helps your dog recover comfortably at home.

Recovery Timeline and Activity

Recovery after Femoral Head Ostectomy (FHO) surgery is gradual and requires careful management of activity to ensure healing and prevent complications.

• Gradual reintroduction of walking: Short, gentle leash walks usually begin about 1 to 2 weeks after surgery, depending on your vet’s advice. Start with 5 to 10 minutes and slowly increase duration as your dog gains strength and comfort.
• Activity restrictions: Avoid running, jumping, climbing stairs, or rough play for at least 6 to 8 weeks. Controlled, low-impact movement protects the surgical site and supports healing.
• Physical therapy: Rehabilitation exercises help rebuild muscle strength, improve joint mobility, and reduce stiffness. Common therapies include passive range-of-motion exercises, underwater treadmill sessions, and gentle stretching.
• Owner’s role: Following your vet’s guidance on exercise and therapy is crucial. Consistent, supervised rehab improves recovery speed and overall outcome.

With proper timing and controlled activity, most dogs regain good function and mobility within 2 to 3 months after FHO surgery. Rehabilitation plays a key role in restoring quality of life.

Monitoring and Follow-up

Scheduled veterinary visits and follow-up care are essential parts of recovery after Femoral Head Ostectomy (FHO) surgery. These appointments help your vet monitor healing progress and catch any complications early.

• Scheduled visits: Your vet will usually schedule check-ups at regular intervals, such as 2 weeks, 6 weeks, and a few months post-surgery. These visits allow close monitoring of your dog’s recovery and adjustment of treatment plans if needed.
• X-rays: Follow-up X-rays help the vet assess the surgical site, check the formation of the “false joint,” and ensure there are no signs of infection or complications. X-rays provide valuable information about bone healing and joint stability.
• What vets look for: During exams, vets check your dog’s pain levels, mobility, muscle strength, and incision healing. They also evaluate the range of motion and watch for signs of swelling, infection, or abnormal joint movement.
• Adjusting care: Based on findings, your vet may recommend changes to medications, physical therapy, or activity levels to support optimal healing.

Regular monitoring and follow-up help ensure your dog’s recovery stays on track, leading to better long-term outcomes and comfort.

Expected Outcomes and Long-Term Recovery

Healing after Femoral Head Ostectomy (FHO) surgery typically takes 8 to 12 weeks. During this time, the body remodels the area where the femoral head was removed, forming a fibrous “false joint” that cushions movement.

• Healing timeline: Bone remodeling and tissue healing improve gradually, with most dogs showing significant progress within two to three months. Muscle strength and joint flexibility increase with physical therapy and controlled exercise.
• Pain and mobility improvements: Most dogs experience substantial pain relief soon after surgery, allowing them to walk, run, and play more comfortably. Mobility steadily improves as the false joint adapts and muscles rebuild.
• Possible permanent limp or altered gait: Some dogs may retain a slight limp or altered gait due to changes in leg length, muscle strength, or joint mechanics. This is usually mild and does not significantly affect quality of life.

With proper care and rehabilitation, FHO surgery offers excellent long-term benefits. Most dogs regain active, pain-free lives, enjoying improved comfort and mobility for years after surgery.

Owner’s Role in Recovery

Owners play a vital role in supporting their dog’s recovery after Femoral Head Ostectomy (FHO) surgery. Your care and attention directly impact how smoothly and quickly your dog heals.

• Monitoring progress: Observe your dog’s movement, appetite, and behavior daily. Watch for signs of pain, swelling, or changes in walking. Keeping a journal can help track improvements or issues to share with your vet.
• Activity restrictions: Strictly follow your vet’s guidelines on limiting your dog’s activity. Prevent jumping, running, or climbing stairs until cleared by the vet. Controlled leash walks should gradually increase as advised.
• Medication compliance: Administer all prescribed medications on time, including pain relief and antibiotics. Proper medication helps control discomfort and prevents infection.
• Supporting rehab: Assist with physical therapy exercises at home as instructed. Gentle stretching and muscle strengthening aid in restoring mobility and strength.
• Providing a safe environment: Create a calm, comfortable space with non-slip surfaces and easy access to essentials.

By staying attentive and following vet instructions, you give your dog the best chance for a full, comfortable recovery and a return to an active life.

If your dog is showing signs of pain or trouble moving their hip, it might be time to consider a surgery called Femoral Head Ostectomy (FHO). This surgery helps dogs with serious hip problems feel better and walk more easily. Knowing the signs your dog needs FHO can help you act early and improve their quality of life.

Signs Your Dog Might Need Femoral Head Ostectomy

Recognizing the signs early helps ensure your dog receives timely treatment for painful hip conditions that may require Femoral Head Ostectomy (FHO) surgery.

1. Difficulty Walking or Limping

Limping or difficulty walking is one of the most obvious signs your dog might need FHO surgery. When the hip joint is painful or damaged, your dog will try to avoid putting weight on the affected leg.

• Your dog may limp continuously or only after exercise.
• Favoring one leg over the other helps reduce pressure and pain in the hip.
• Difficulty walking may present as slow, hesitant steps or reluctance to move.

This limping indicates that the hip joint is not functioning properly due to pain, arthritis, fracture, or other damage. Persistent limping despite rest or medication is a strong sign that surgical intervention like FHO could be necessary.

2. Abnormal Gait or Favoring One Leg

An abnormal gait means your dog’s walking pattern changes because of discomfort or weakness. Dogs with hip problems may shift their weight unevenly, causing visible changes in how they move.

• Your dog may “swing” the affected leg or take shorter steps on that side.
• Uneven weight distribution may cause limping or skipping.
• The gait may look unbalanced or awkward, especially after activity.

These changes result from pain or instability in the hip joint. Abnormal gait often worsens over time and is a clear signal to consult your vet for possible surgery.

3. Loss of Weight-Bearing on the Affected Leg

Loss of weight-bearing means your dog refuses to put any weight on the painful leg. This is a severe sign of hip dysfunction and pain.

• Your dog may hold the leg completely off the ground while standing or walking.
• This can occur suddenly or develop gradually with worsening discomfort.
• Loss of weight-bearing leads to muscle weakness and further mobility issues.

When your dog stops using the leg due to pain, it often indicates advanced joint damage requiring surgical treatment such as FHO for pain relief and function restoration.

4. Persistent Hip Pain or Discomfort

Persistent hip pain affects your dog’s quality of life and is a common reason for FHO surgery.

• Your dog may show signs of discomfort such as whining or reluctance to move.
• Pain might be constant or worsen after activity.
• Hip pain reduces interest in walks, play, and normal activities.

Ongoing pain means conservative treatments are not controlling the condition, and surgery may be the best option to restore comfort and mobility.

5. Decreased Activity or Reluctance to Play

Changes in activity level are often one of the first signs owners notice when their dog is in pain.

• Your dog may avoid running, jumping, or climbing stairs.
• Reduced playfulness and slower movements indicate discomfort.
• Reluctance to exercise can lead to weight gain and muscle loss.

This behavior change shows your dog is trying to avoid pain, which may signal the need for surgical intervention like FHO.

6. Stiffness in the Hip Joint, Especially After Rest

Stiffness after rest or sleep is common in dogs with hip joint problems.

• Your dog may be slow to stand or walk after naps.
• The hip may feel tight or rigid, limiting movement temporarily.
• Stiffness often improves with gentle activity but returns after resting.

This stiffness indicates joint inflammation or damage, which may require surgery if it significantly impacts mobility.

7. Pain When the Hip Is Manipulated or Touched

During veterinary exams, pain responses when the hip is moved or touched can confirm joint problems.

• Vets check for tenderness by gently manipulating the hip joint.
• Pain during these tests often correlates with arthritis, fractures, or hip dysplasia.
• A painful response supports the need for further treatment or surgery.

This exam finding helps vets decide if FHO surgery is appropriate for your dog’s condition.

8. Limited Range of Motion in the Hip

A reduced ability to move the hip joint shows stiffness and pain.

• Your dog may struggle to fully extend or flex the leg.
• Limited motion causes difficulty in walking, running, or climbing.
• This restriction often worsens over time without treatment.

Limited range of motion is a key symptom indicating severe joint damage that may benefit from FHO surgery.

9. Muscle Loss or Atrophy in the Affected Leg

Muscle wasting happens when a dog stops using the painful leg regularly.

• You may notice the leg looks thinner or weaker compared to the other side.
• Muscle loss reduces joint support and slows recovery.
• Atrophy often signals chronic discomfort and long-term mobility issues.

Muscle loss is a serious sign that conservative care is no longer enough, and surgical options should be considered.

10. Chronic Lameness Not Improving Over Time

Lameness that does not improve with rest or treatment indicates the need for further evaluation.

• Persistent limping despite medication or physical therapy shows worsening hip disease.
• Chronic lameness reduces your dog’s activity and quality of life.
• This symptom often leads vets to recommend FHO surgery for pain relief.

Ignoring ongoing lameness can cause further joint damage and pain.

11. Joint Instability or Looseness Detected by the Vet

During exams, vets may find instability or looseness in the hip joint.

• The hip may feel unstable or shift abnormally during manipulation.
• Joint instability increases pain and risk of further injury.
• This finding supports surgical intervention to stabilize the joint and relieve pain.

Hip instability is often a clear reason to consider FHO surgery.

12. Reduced Quality of Life Due to Hip Issues

Chronic hip pain and mobility problems can greatly reduce your dog’s happiness.

• Dogs may become withdrawn, less playful, and reluctant to exercise.
• Pain and difficulty moving affect daily activities like walking or climbing stairs.
• Improving quality of life is a primary goal of FHO surgery.

If hip problems interfere with your dog’s enjoyment of life, surgery may provide relief and restore activity.
