Post-Surgery Red Flags: When to Call Your Vet

Educational guide · Updated July 2026 · Not veterinary advice

Call your veterinarian if your dog's incision shows spreading redness, discharge, odour, or heat, or if your dog vomits repeatedly, refuses food for more than a day, or becomes unusually lethargic. Pain that medication does not settle and any loss of mobility your dog had already regained also warrant a call. When in doubt, phone the clinic. Calling early is never the wrong move.

What does a normal incision look like?

Knowing normal is half the battle. In the first few days, expect the incision edges to be lightly pink, held neatly together, with mild swelling and perhaps a little bruising around the site. A tiny amount of clear or slightly blood-tinged seepage in the first 24 hours can be normal. From there, the trend matters most: a normal incision looks a little better every day, and the skin typically seals in 10 to 14 days, which is when stitches or staples usually come out.

Take a photo of the incision each morning in the same light. A daily photo makes gradual changes obvious and gives your veterinary team something concrete to look at if you call.

What are the signs of an incision infection?

Any of the following is a same-day call to your veterinarian:

  • Redness that spreads outward from the incision line rather than fading
  • Discharge, especially yellow or green, or any ongoing seepage after the first day or two
  • An unpleasant odour from the site
  • Heat, where the skin around the incision feels noticeably warmer than elsewhere
  • Swelling that grows instead of settling, or a gap opening between the edges

Infections caught early are usually simple to manage. Infections caught late can undo a surgery. Keep the cone or recovery suit on, since licking is the most common way an incision gets contaminated in the first place.

Which whole-body signs should worry me?

Problems do not always show up at the incision. Watch the whole dog. Some grogginess and a skipped meal on the first evening home are common after anesthesia. Beyond that window, call your veterinarian about:

  • Vomiting more than once, or any vomiting paired with a dog who seems unwell
  • Appetite loss lasting more than a day
  • Lethargy that deepens instead of lifting after the first 24 to 48 hours
  • Diarrhea that persists, or very dark, tarry stool

Our post-surgery checklist lays out what to monitor each day so nothing slips past a busy household.

What if pain medication does not seem to help?

Prescribed pain control should keep your dog reasonably comfortable. Signs it is not doing its job include crying or whining that keeps returning, panting at rest, trembling, guarding the surgical area, refusing to lie down, or restlessness that peaks at night. Do not wait this out and do not add human pain medications, which can be dangerous for dogs. Call your veterinarian. Dosing can very often be adjusted quickly, and unmanaged pain slows everything down.

What counts as mobility regression?

Recovery is rarely perfectly smooth, but the overall direction should be forward. Regression means losing ground your dog had already gained: a leg that was bearing weight is suddenly held up, a new limp appears, or your dog refuses to stand or walk when they had been moving comfortably. That pattern warrants a call the same day.

This matters most once strengthening begins, typically in weeks 5 to 8 with your veterinarian's approval. Structured, vet-approved exercises on stable equipment, like gentle balance standing on a balance disc with base or a low platform such as the bone balance disc, should support recovery, not set it back. Mild tiredness after a session is expected. A worse limp the next morning is not, so stop the exercises and check in with your vet. For a sense of the normal arc, see what the first 8 weeks of recovery usually look like.

When is it an emergency right now?

Skip the phone tag and go to your veterinarian or an emergency clinic immediately for any of these:

  • Difficulty breathing, or gums that look pale, white, or blue
  • Collapse or inability to wake your dog
  • An incision that opens widely, bleeds steadily, or shows tissue protruding
  • Repeated vomiting or a swollen, tight belly
  • No urination for more than 24 hours
  • Seizures or sudden disorientation

Keep the number of your nearest 24-hour clinic saved before you need it.

Why is calling early always the right move?

Veterinary teams would far rather answer ten unnecessary calls than miss one real problem. Early calls are cheap: often a quick reassurance, a photo review, or a small medication tweak. Late calls are expensive, sometimes in money, sometimes in setbacks measured in weeks. You know your dog better than anyone. If something feels off, trust that instinct, pick up the phone, and let the professionals tell you it is nothing. That phone call is never wasted.

Common questions

Owners also ask

What should a normal incision look like a week after surgery?

By day seven, the incision should look calmer than it did on day one: edges together, pinkness fading, swelling mostly gone, and no discharge. The skin typically seals fully in 10 to 14 days. If redness is spreading, the site feels hot, or you see any coloured discharge or odour, call your veterinarian that day rather than waiting for the recheck.

Is a little clear discharge normal?

A small amount of clear or slightly blood-tinged seepage can be normal in the first 24 hours. After the first day or two, ongoing discharge of any kind is worth a call, and yellow or green discharge, odour, or spreading redness are signs of possible infection that need same-day attention. When unsure, send your clinic a photo and ask.

My dog skipped a meal after surgery. Should I worry?

One skipped meal on the first evening home is common after anesthesia and usually nothing. The line to watch is a full day: appetite loss lasting more than 24 hours, or any refusal to eat combined with vomiting or lethargy, means call your veterinarian. Offering a bland, vet-approved meal can help a queasy dog restart eating.

Can I clean the incision myself?

Only as directed by your veterinarian. Most incisions do best kept clean and dry, with no bathing until cleared. Avoid hydrogen peroxide and alcohol, which damage recovering tissue, and never apply creams or ointments unless prescribed. Your two best tools are the cone or recovery suit to prevent licking and a daily photo to track changes.

A training tool for dogs, not a toy. Always supervise your dog during use, check and trim nails before sessions, and consult your veterinarian before beginning any new rehabilitation or exercise program.
