What to do now

  1. Call your vet now, even if the bite looks small.
  2. For heavy bleeding, press a clean, dry dressing on the wound and go straight to a vet.
  3. For small bites, flush the wound with lukewarm salty water.
  4. Go to an emergency vet if your dog has trouble breathing, pale gums or collapses.

Don't

  • Don't clean a bite wound with hydrogen peroxide unless your vet tells you to.

Symptoms to watch for

  • Puncture wounds that may be hidden by fur
  • Bleeding
  • Limping or crying
  • Weakness
  • Trouble breathing
  • Pale or blue gums
  • Collapse

Why

Teeth can crush and tear tissue under the skin, and a dog's mouth is full of bacteria, so all bite wounds are treated as infected.
