Bed Sores on Dogs Causes Treatment and Prevention

Bed sores in dogs also called pressure sores or decubitus ulcers develop when prolonged pressure on a bony area cuts off blood supply, causing the tissue to break down. They are the same condition as bedsores in hospitalized humans, and they are just as serious when they reach advanced stages.

The good news is that early-stage bed sores are very treatable at home. The bad news is that they can progress from a small red patch to a deep infected wound within days if not caught and addressed.

 

Quick answer: Bed sores form over bony prominences like elbows and hips when sustained pressure blocks blood flow. Most common in senior, large-breed, and immobile dogs. Early stages respond to soft bedding and repositioning; advanced stages need veterinary care.

 

Key takeaways

  • Bed sores form over bony prominences: elbows, hips, hocks, stifles, and sides of the knees
  • Four stages exist: from mild redness to deep infected wounds reaching muscle and bone
  • Senior dogs, large breeds, and post-surgical dogs are at highest risk
  • Stage 1 sores reverse with home management: soft bedding and repositioning every 2 to 4 hours
  • Stage 3 and 4 sores need veterinary debridement and often systemic antibiotics
  • Thick orthopedic foam bedding is the single most effective prevention measure for at-risk dogs

What causes bed sores in dogs?

Bed sores develop when the weight of a dog's body continuously presses a bony prominence against a hard surface. Walkin' Pets explains the mechanism: "Decubital ulcers form when repeated pressure on an affected area constricts the blood vessels, decreasing the area's blood supply and as the skin is deprived of oxygen, it begins to die."

Once the tissue starts to die, it creates a wound that bacteria readily colonize. This is why advanced bed sores are almost always infected.

The process requires two things to come together: sustained mechanical pressure and skin that is not being repositioned or protected. Any dog that lies in the same position for hours without shifting is at risk.

Additional factors that increase risk

Incontinent dogs: urine-soaked skin breaks down much faster under pressure. Walkin' Pets advises that "reducing skin moisture from urine is important to help prevent the bacterial growth and skin degradation that contribute to pressure sores."

Thin or underweight dogs: less muscle and fat over bony prominences means the bone contacts the surface with less cushioning.

Obese dogs: more body weight concentrates greater compressive force at each contact point.

Dogs on hard floors: concrete, hardwood, and tile dramatically increase the pressure at contact points compared to soft surfaces.

Which dogs get bed sores?

Dr. Buzby's ToeGrips identifies the most at-risk groups:

  • Senior dogs: reduced muscle mass, reduced mobility, longer periods in one position
  • Large and giant breed dogs: more body weight, greater force at bony contact points
  • Post-surgical patients: strict rest requirements limit natural repositioning
  • Paralyzed or paraplegic dogs: unable to shift position at all
  • Dogs with arthritis: pain limits movement and encourages sustained resting in one position
  • Short-coated breeds: less coat padding between skin and hard surfaces

DogCancer.com notes that bed sores can also be a concern for dogs in late-stage cancer, where weakness and pain significantly reduce their ability to reposition.

The 4 stages of bed sores

Recognizing the stage determines the treatment approach.

Stage 1: redness and intact skin

The skin over the bony prominence is red, warm, and may have some hair loss. The surface is not broken. This is the ideal intervention point.

What to do at home: add thick orthopedic padding under the affected area, increase repositioning to every 2 hours, and monitor the site twice daily. Most Stage 1 sores reverse completely with these measures.

Stage 2: shallow open wound

The skin has partially broken down. A shallow blister or open area appears. The surrounding tissue remains inflamed and warm.

WagWalking: "Stage 1 ulcers may improve with padding, regular repositioning of the dog, and a quality moisture-wicking dog bed. Vets may instruct pet parents to regularly apply moist dressings to open pressure sores."

What to do: contact your vet. Stage 2 requires wound cleaning, appropriate dressings, and assessment for infection. Antibiotics may be started if signs of infection are present.

Stage 3: full-thickness wound

The sore extends through the full skin thickness into subcutaneous tissue. VetMobile describes what you see: "The sore becomes deeper and it may extend into the underlying tissue, such as the muscle layer. Pus or discharge may be present. At this stage, the area is surrounded by dead or dying tissue."

What to do: veterinary care is required. Treatment involves debridement of dead tissue, wound culture, and systemic antibiotics based on culture results.

Stage 4: bone or muscle involvement

The wound extends to muscle, tendon, or bone. This is a serious and potentially life-threatening stage. Bacteria can enter the bloodstream from a Stage 4 wound, causing sepsis.

What to do: emergency veterinary care. Hospitalization, IV antibiotics, surgical debridement, and reconstructive surgery may be necessary.

2Shallow open wound or blisterVet wound care, moist dressings, possible antibiotics
3Full-thickness wound with dischargeDebridement, culture, systemic antibiotics
4Muscle or bone involvedSurgery, hospitalization, IV antibiotics

 

Home wound care for Stage 1 and 2

For Stage 1 and early Stage 2 sores, clean the area daily with dilute chlorhexidine solution (not hydrogen peroxide, which damages healing tissue). Apply a non-adherent wound dressing and change it once or twice daily. Keep the area dry between dressing changes.

Puainta recommends: "Pressure Relief: Encourage the dog to change positions frequently. Soft Bedding: Provide cushioned surfaces to reduce pressure. Cleanliness: Keep the area clean and dry."

For incontinent dogs, clean and dry the skin after every urination. Use a waterproof mattress cover that can be washed daily. Sheepskin pads are effective at wicking moisture away from skin while providing cushioning.

For how bed sores relate to callus formation at the same pressure sites, see calluses from similar pressure points.

When to call the vet

Call your vet within 24 hours if:

  • The wound is open, moist, or has any discharge
  • The area is warm and the dog shows signs of pain when the area is touched
  • The sore is growing despite home management
  • Your dog is lethargic, off food, or running a fever

These signs suggest infection is establishing. Early antibiotic treatment is significantly more effective than treating advanced infection.

WagWalking notes: "Antibiotics may be necessary if the wound is infected or at risk of becoming infected. Antibiotics have minimal risks and a high success rate when used early on."

For how the progression of pressure necrosis connects to bed sore development, see pressure necrosis in severe bed sore cases.

Prevention

Orthopedic bedding

The most effective single intervention. Memory foam or high-density egg-crate foam distributes weight across a larger surface area, reducing peak pressure at bony contact points. Petful emphasizes that "you might be more likely to notice pressure sores in dogs if you have a large breed pup or a short-haired breed" both groups where bedding choice is critical.

The foam must not fully compress under the dog's full weight. Test by pressing firmly: if it bottoms out quickly, it is not thick enough. For large dogs, minimum 4 inches of high-density foam is recommended.

Repositioning schedule

Reposition immobile dogs every 2 to 4 hours, alternating which side bears weight. Walkin' Pets advises: "Try not to let the dog rest on the hip bone on one side for very long, reposition your pet every 2 to 3 hours."

If you are not home during the day, consider whether a pet sitter or midday check can provide repositioning support for a dog with high risk.

Daily inspection

Check every bony prominence every day. Run your hand along the elbows, hips, hocks, and knees. Hair loss is the first visible sign act at Stage 1, before any skin breakdown occurs.

Moisture management for incontinent dogs

Wet skin under pressure breaks down dramatically faster than dry skin. Change diapers and male wraps frequently. Use raised mesh beds for overnight rest in incontinent dogs urine drains through rather than pooling under the dog. Walkin' Pets recommends sheepskin pads specifically for their wicking properties.

For how swelling associated with bed sores can extend to the feet and lower legs, see swelling associated with pressure injuries.

Frequently asked questions

How do I know if my dog has a bed sore starting?

The first sign is a small patch of hair loss over a bony area, sometimes with mild redness and warmth. The skin is still intact. Run your hand over the elbows, hips, and hocks daily in at-risk dogs. Acting at this point before the skin opens is far easier than treating an open wound.

Can bed sores in dogs heal on their own?

Stage 1 sores can reverse with prompt management: improved bedding, repositioning, and keeping the area dry. Stage 2 and above rarely resolve without veterinary intervention. The wound environment actively promotes bacterial growth, which prevents natural healing without treatment.

How long does a bed sore take to heal in a dog?

Stage 1 sores managed early typically show improvement within 1 to 2 weeks with good home care. Stage 2 wounds typically heal in 3 to 6 weeks with consistent veterinary wound care. Stage 3 and 4 wounds may take months and may not fully close in all cases.

My senior dog keeps getting bed sores despite soft bedding. What else can I do?

Check whether the foam has compressed over time and needs replacing. Add protective wraps (elbow pads or hock wraps) over at-risk sites. Increase repositioning frequency to every 2 hours. Consult your vet about whether the dog's underlying mobility level has declined and whether additional pain management or physiotherapy could help. Nutritional support including protein and vitamin C promotes skin healing.

Are bed sores painful for dogs?

Stage 1 sores are usually not painful. Stage 2 onward becomes progressively more painful as the wound deepens and infection sets in. Dogs with painful bed sores may lick or bite at the area, avoid lying on that side, or show behavioral changes. Pain management from your vet is an important part of treatment from Stage 2 onward.

Can bed sores become life-threatening in dogs?

Yes. Stage 3 and 4 sores can allow bacteria to enter deeper tissues and the bloodstream, causing sepsis. A dog with an advanced bed sore that is also lethargic, not eating, or running a fever is potentially septic and needs emergency veterinary care the same day.

Step #1

Getting Ready

Ensuring a clean surgical field starts with proper skin preparation. This video demonstrates the best practices for:

  • Shaving the patient – Achieving a close, even shave while minimizing skin irritation
  • The Dirty Scrub – The initial skin prep step to remove surface debris and reduce bacterial load before the sterile scrub.

Following these techniques helps reduce infection risk and improve surgical outcomes. Watch the video to see how it’s done effectively!

Step #2

Reduce Your Risks

Many surgeons are shocked to find out that their patients are not protected from biofilms and resistant bacteria when they use saline and post-op antibiotics.

That’s Where Simini Comes In.

Why leave these risks and unmanaged?  Just apply Simini Protect Lavage for one minute. Biofilms and resistant bacteria can be removed, and you can reduce two significant sources of infection.
