What’s Normal and What’s Not After Soft Tissue Surgery

After soft tissue surgery, it’s normal for your dog to act a bit tired and quiet. You might see mild bruising or swelling near the incision site. This is a normal part of healing and should improve over a few days. Your dog may eat less and sleep more during the first 24 to 48 hours.

Some redness and scabbing around the stitches can also be expected. The area should stay clean and dry, and the swelling should not get worse. If your dog is calm, walking slowly, and showing interest in food or water by the second day, that’s a good sign.

  • Normal signs: Mild swelling, scabbing, slight redness, low energy, reduced appetite
  • Watch closely: Any changes that worsen or don’t improve after two days

Knowing what’s normal helps you catch complications early.

Red Flags to Watch for at the Incision Site

Even small changes at the incision site can signal serious problems—knowing what to look for makes a difference.

Signs of Infection or Poor Healing

An incision should improve a little every day. If it starts to look worse instead of better, that’s a red flag. Infection often begins with redness that spreads or becomes brighter. Swelling that feels hot or painful can also be a sign. If you notice thick discharge—especially yellow, green, or foul-smelling—call your vet right away. Other warning signs include a bad odor from the bandage, dark or blackened skin near the wound, or excess bleeding or pus.

Poor healing may happen if your dog is licking, scratching, or too active. Keep the incision dry, clean, and protected. Take photos daily to track progress and catch early changes.

  • Redness that worsens or spreads
  • Swelling that feels warm, painful, or keeps growing
  • Yellow, green, or smelly discharge
  • Pus, blood, or moisture leaking from the wound
  • Skin turning dark, cold, or dry around the incision
  • Bad smell coming from the bandage

These signs usually mean the wound needs medical attention right away.

When the Incision Opens Up

A healing incision should stay closed and dry. If the wound splits or opens, this is called dehiscence—and it needs urgent vet care. You might see the skin gaping, with tissue, fat, or fluid bulging through. This often happens when a dog licks, chews, or moves too much. Some wounds may look wet or shiny before opening fully.

Loose or missing stitches, especially those that seem chewed out, should never be ignored. The skin might look pulled apart, with less redness around the edges due to tension. If the incision opens, keep your dog calm and prevent more movement until you can reach the vet.

  • Stitches that come loose or fall out early
  • Skin that looks pulled open or stretched
  • Bulging fat or soft tissue under the skin
  • Wet, shiny, or sticky surface over the incision
  • Gaping wound with pink or yellow tissue showing

If the wound opens, cover it gently with a clean cloth and contact your vet right away. Avoid pressure, creams, or cleaning until you get professional advice.

Unusual Behavior and Physical Signs of Complications

Behavioral changes often appear before visible symptoms—watch your dog closely during recovery.

Whining, Pacing, or Hiding

If your dog begins to act differently after surgery, pay close attention. Whining, pacing, or hiding can be early signs of pain, stress, or infection. Some dogs may act restless and can’t seem to get comfortable. Others might isolate themselves or avoid touch. While a little discomfort is normal, a sudden change in behavior usually signals that something isn’t right.

You may also notice panting without heat or exercise, looking anxious, or constantly shifting positions. These behaviors often mean your dog is uncomfortable and may need pain relief or a wound check.

  • Whining or crying without reason
  • Pacing around or unable to settle
  • Hiding under beds or in closets
  • Avoiding people or eye contact
  • Trouble sleeping or lying still

These behavior shifts should not be ignored. If your dog shows new or worsening signs after the first two days, call your vet. Pain or discomfort left untreated can delay healing or lead to other complications.

Systemic or Internal Complications

Not all complications are visible—some affect your dog’s entire body and require fast action.

Internal Bleeding or Shock

Internal bleeding is rare but serious. It can happen if a blood vessel wasn’t sealed properly or if your dog became too active too soon. One of the first signs is pale gums or tongue—normal gums should be pink. Your dog may also appear very weak, unsteady, or collapse suddenly. Cold limbs, shaking, or low body temperature are also red flags.

These signs may appear suddenly or come on slowly over several hours. If you notice more than one of them, get emergency help right away. Internal bleeding can quickly become life-threatening if not treated.

  • Pale or white gums or tongue
  • Sudden weakness or collapse
  • Shaking or trembling for no reason
  • Cold paws, ears, or limbs
  • Fast breathing or rapid heart rate

If you suspect internal bleeding, do not wait. Carry your dog gently and call your vet or the nearest emergency clinic immediately.

Infection or Fever

A fever is your dog’s way of fighting off infection—but it’s also a sign something may be wrong. After surgery, your dog should slowly gain energy. If they seem more tired after the second day or feel hot to the touch, this may signal an internal infection.

Fever can come with body aches, decreased appetite, or changes in breathing. Touch your dog’s ears, paws, or armpits—if they feel much warmer than usual, it’s a warning sign. In some cases, dogs may limp or show pain even if the surgical site looks okay.

  • Body feels hot, especially ears and paws
  • Lethargy that worsens instead of improving
  • Refusal to eat or drink
  • Shivering or acting cold in a warm room
  • Limping or guarding part of the body

Don’t give fever-reducing medicine meant for humans. Call your vet if you notice these signs—they’ll check for infection and may prescribe antibiotics or further testing.

Digestive or Urinary Issues

After surgery, your dog’s bathroom habits might change slightly—but major changes can signal deeper problems. If your dog hasn’t urinated for more than 24 hours, that’s a concern. Straining to pee, leaking urine, or crying while urinating are also red flags.

Digestive issues like constipation, diarrhea, or belly swelling could mean the medications are affecting your dog’s system—or worse, that an internal issue is developing. A swollen belly could also mean fluid buildup or gas that needs immediate care.

  • No urination in 24 hours
  • Straining, crying, or leaking while urinating
  • Constipation lasting over 48 hours
  • Pain when pooping or signs of bloating
  • Hard, swollen belly or visible discomfort

Keep a close eye on bathroom patterns and tell your vet about any problems. The earlier you catch internal issues, the easier they are to treat.

Rare but Serious Signs to Know

Some complications are uncommon—but when they happen, they need urgent care.

Seromas and Fluid Pockets

A seroma is a soft, fluid-filled swelling near the incision. It often looks like a small balloon under the skin. These usually form when fluid collects in the empty space created during surgery, especially if your dog moved too much early on. Seromas aren’t usually painful, but they can grow if not monitored.

In most cases, your vet may just observe it and let the fluid absorb on its own. But if it becomes red, warm, or starts leaking, it may need to be drained. Never try to pop or press on a seroma at home.

  • Soft swelling near the incision site
  • Usually not warm or painful at first
  • May jiggle when touched
  • Can appear several days after surgery
  • Needs vet attention if it grows, leaks, or changes color

If you suspect a seroma, keep your dog calm and call your vet. It may not be an emergency—but it does need professional review.

Crepitus or Skin Necrosis

Crepitus is a crackling or popping sound under the skin. It happens when gas builds up in the tissues, sometimes from bacteria. It’s rare, but dangerous. If you feel this when touching near the wound, it must be reported to your vet immediately.

Skin necrosis is when tissue starts dying. It can happen if the blood flow to the area is reduced—often due to infection, pressure, or tight stitches. The skin may turn gray, cold, flaky, or begin peeling. This condition is serious and may require wound cleaning, new sutures, or even surgery.

  • Crackling under the skin (crepitus)
  • Skin turns gray, purple, or cold
  • Dry, flaky, or peeling wound edges
  • Loss of skin around the incision
  • Strong odor or deep darkening of tissue

These signs mean urgent tissue damage is happening. Call your vet or go to the nearest emergency center right away—this is not something that can wait.

When to Call Your Vet Immediately

Some symptoms can’t wait; quick action could save your dog’s life or prevent major complications.

During recovery, there are certain signs that require immediate veterinary help. Bleeding from the incision, especially if it soaks through a bandage, is always urgent. Pus or fluid leaking from the wound can signal a serious infection. Gums that look pale, blue, or gray may indicate internal bleeding or lack of oxygen, both are emergencies.

Other signs like collapse, refusal to move, or extreme pain should never be ignored. Vomiting, diarrhea, or a high fever that doesn't improve within 12–24 hours may point to infection or a reaction to medication. Finally, if your dog hasn't urinated or had any interest in water for more than 24 hours, it’s time to call the vet.

  • Bleeding or pus from the incision
  • Gums that appear pale, gray, or blue
  • Sudden collapse or extreme stiffness
  • Refusing to move, eat, or drink
  • Vomiting, diarrhea, or fever not improving
  • No urination in 24+ hours

These signs mean something serious may be happening. Don’t wait—get help from your vet or an emergency clinic right away.

Final Thoughts

Some swelling or bruising is normal—but trust your gut when something feels wrong.

Recovering from soft tissue surgery takes time, patience, and close observation. While many signs like mild bruising, sleepiness, or low appetite are normal in the first day or two, it’s important to watch for changes that go beyond typical healing. Trust what you see and feel—if your dog’s condition seems off or getting worse, you’re probably right to be concerned.

Taking clear photos of the incision site every day can help you compare healing progress and spot problems early. If you’re unsure whether something is normal, it’s always better to call your vet. Most complications can be managed well when caught early.

  • Mild swelling, scabbing, or bruising is usually normal
  • Keep a consistent routine and check the wound daily
  • Use photos to track healing and catch red flags
  • Watch behavior closely, changes often appear before visible signs
  • Never wait if something feels wrong; call your vet

Your care plays a big role in how well your dog heals. With attention and quick action, most dogs recover smoothly.

FAQs

How do I know if my dog’s incision is healing properly?

A healing incision should look dry, closed, and slightly pink. Mild bruising or swelling is normal in the first few days. It should not be redder, smell bad, or leak fluid. If you're unsure, take daily photos to track progress and call your vet if anything looks worse.

What are warning signs of infection after soft tissue surgery?

Infection signs include redness that spreads, hot or swollen areas, yellow or green discharge, foul odor, or increased pain. Your dog may also act more tired or refuse food. Any of these signs should be reported to your vet immediately.

Is it okay if my dog is not eating after surgery?

It's normal for dogs to have low appetite for 24–48 hours. Offer bland food and fresh water. If your dog refuses to eat or drink beyond that time, or shows vomiting or diarrhea, call your vet.

How can I tell if my dog is in pain during recovery?

Signs of pain include whining, panting, shaking, pacing, or not wanting to move. Some dogs hide or become aggressive when they hurt. If you see any of these behaviors, speak to your vet about pain relief options.

What does it mean if the incision opens?

If the incision splits or gapes, this is called dehiscence. You might see loose stitches, bulging tissue, or shiny wet areas. Cover it gently and call your vet right away. Do not clean or apply anything to the wound without guidance.

When should I go to the emergency vet after soft tissue surgery?

Go immediately if your dog collapses, has pale gums, strong bleeding, a foul-smelling wound, or can’t walk or pee. Sudden changes in behavior, vomiting that won’t stop, or signs of shock also need emergency care.

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.
