Dog’s Incision Looks Open After Surgery: What Now?

5 min readOct 25, 2026

General guidance — not a diagnosis. When in doubt, call your vet.

Call about separated edges

If your dog's surgical incision looks open, has a new gap or has lost stitches, contact the surgical team promptly. Do not glue it, push the edges together or assume that only the skin is affected. A widely open wound, protruding tissue, heavy bleeding or a weak, collapsed dog needs emergency assessment.

ACVS describes a healing incision as generally clean and dry, with closed edges, and lists opening, increasing redness, swelling, discharge and odor as reasons to contact the veterinary team.[1] A photograph may help explain the change, but it cannot establish wound depth or replace an examination.

Have the discharge instructions available when you call. Give the surgery date, procedure, incision location and when you first noticed the change. Explain whether the area was supposed to be fully closed or whether the surgeon intentionally left a drain or another opening. If you do not know, ask rather than treating a gap as an expected drain site.

Observe without pulling or probing

Look in good light without stretching the skin apart. Note whether the edges meet, whether material is missing, whether there is fluid and whether your dog seems painful. Do not insert a cotton swab, finger or instrument to find out how deep a gap extends. Avoid pressing on a new swelling to see whether it disappears.

Mild bruising and redness can occur during early healing, but they are different from an incision separating. ACVS also distinguishes limited immediate postoperative seepage from ongoing discharge, thick fluid or foul odor that should be reported.[1] Describe the trend instead of deciding from color alone that the wound is infected or safe.

External stitches are not used for every closure. Some wounds have buried absorbable sutures, while others have skin sutures or staples. Ask the team which was used; not seeing a row of stitches does not prove they fell out. Conversely, visible stitches remaining in place do not guarantee that every part of the incision is intact.

Take a clear photo if the team requests one and your dog is comfortable enough. Record the time and avoid repeatedly handling the site for better pictures. Report other changes, including appetite, activity, vomiting and difficulty moving, rather than sending a close-up with no history.

Protect the site and arrange reassessment

Use the protective collar prescribed at discharge, and tell the clinic if your dog can still reach the incision. Tufts' surgical aftercare guidance emphasizes using the prescribed protective collar to prevent licking or chewing at the incision.[2] A recovery suit or alternative collar is appropriate only if the treating team agrees it protects this particular site.

Keep your dog calm and follow its activity restriction while arranging the visit. Do not allow running or jumping to test whether the wound hurts. Ask for help with transport if the procedure limits safe lifting or walking. Postoperative care after spay or neuter surgery still needs the same attention to the individual discharge plan.

Do not apply peroxide, alcohol, ointment, household glue or adhesive strips to repair the incision. Avoid bathing the area, removing sutures or starting leftover antibiotics. ACVS advises keeping incisions dry and withholding topical products unless the veterinary team directs their use.[1]

If a dressing covers the site, do not unwrap it just to obtain a photograph unless instructed. Report a wet or slipping bandage, new odor or fluid soaking through. The team can explain what to do while you travel.

This guide cannot determine which tissue layers are affected or whether another closure is needed. Contact the surgeon even if your dog seems comfortable; the appearance, procedure and overall condition guide the next step.

When to See a Vet

  • Seek emergency care for protruding tissue, a widely gaping incision, heavy bleeding, collapse or marked weakness.
  • Contact the surgical team promptly for separated edges, missing stitches or a new opening, even if your dog is eating and active.
  • Call urgently for increasing swelling or redness, thick discharge, foul odor or worsening pain around the incision.
  • Contact the clinic if licking or chewing cannot be prevented, or if a bandage is wet, displaced or soaking through.

Frequently Asked Questions

Is a small gap in my dog’s incision normal?

Do not assume a new gap is normal. Some procedures involve a planned opening or drain, but the surgical team should confirm whether what you see matches that plan. Report the location and change promptly, and do not stretch the skin to measure or inspect it.

Can I glue my dog’s incision closed at home?

No. Do not use household glue, skin adhesive, tape or a new tight bandage to close it yourself. The veterinarian needs to assess tissue condition and the reason it opened before deciding on treatment. Prevent licking and follow the clinic’s instructions while arranging assessment.

Does redness mean the incision is infected?

Not by itself. The trend, pain, discharge, odor and overall condition matter, and some redness can accompany early healing. Report worsening changes rather than diagnosing infection from a photograph. Do not start leftover antibiotics or put a topical product on the area without instructions.

What if I cannot see stitches after surgery?

Ask which closure technique was used. Buried absorbable sutures may not be visible, while other closures use external sutures or staples. Do not pull at the edges to look for them. A new gap, discharge or a change in comfort still needs veterinary advice regardless of the closure type.

Can the incision wait until the scheduled recheck?

Call when you notice the change instead of deciding to wait. The team may want an earlier examination or direct you to an emergency service. A dog who is still playful has not proved that an open incision is harmless, so maintain its prescribed activity restriction.

Will my dog need another surgery if the incision opens?

That cannot be decided remotely. Treatment depends on the procedure, location, depth, tissue condition and whether infection or another complication is present. Ask the examining veterinarian about the options after assessment; neither a small surface gap nor an alarming photo predicts the entire treatment plan.
