What should I do if my dog is attacked by another dog?

Published October 27, 2026

The short answer

Get both dogs separated without putting hands near mouths or collars — a loud noise, water thrown over them, or a jacket dropped between them is safer than grabbing, and a lead around a hind leg can pull a dog back if you must intervene. Once apart, keep your dog still and check him slowly: punctures hide in fur and bleed less than they should, so part the coat over neck, chest, and legs, and treat any bite wound, limp, or laboured breathing as a same-day veterinary visit, because bites crush and infect beneath the skin. Note the other owner's details if safe. Your dog's wound notes and visit history belong in his KinsLe Pet Passport for the follow-up checks.

Breaking up a fight without becoming a casualty

Most bite injuries to owners happen during the fight, not after it, because hands near collars and jaws meet teeth in the chaos. Use distance methods first: a sharp loud noise, a bucket or bottle of water thrown over the dogs, a coat or board placed between them, or car doors slammed nearby can break focus for the second you need. If you must physically intervene, the safer method is to lift or pull a dog backward by the hind legs or slip a lead around a hind leg and draw him away, keeping your hands far from heads. Never reach in to pry jaws apart, and once the dogs separate, create real distance — behind a gate, into a car — because fights often restart in the first minute.

Calm your dog and control what you can

Expect shaking, panting, and either clinginess or a strange, wired brightness; adrenaline masks pain in dogs just as it does in people. Keep him on a lead, stop the walk, and speak quietly while you run your hands slowly over him. Press a clean cloth or clothing firmly on anything bleeding steadily and keep the pressure on during the journey rather than lifting it to peek. If he is struggling to breathe, has pale gums, cannot bear weight, or is becoming drowsy, this is no longer a drive-to-the-usual-clinic situation — phone the nearest emergency veterinary service and go.

The wound check that matters most

Bite wounds deceive: two small punctures on the surface can sit over torn muscle and a pocket of crushed, contaminated tissue beneath, and teeth carry bacteria deep as they puncture. Part the fur carefully over the neck, shoulders, chest, belly, and legs, looking for punctures, swelling, and grazes, and watch for the delayed signs over the next two days: a warm swelling, discharge, a new limp, loss of appetite, or a dog who growls when one spot is touched. Because of the infection and crush risk, any bite that broke skin deserves a same-day veterinary assessment even when your dog seems himself; wounds to the chest, neck, abdomen, eyes, or genitals, and any attack on a puppy, a senior, or a very small dog, are urgent regardless of appearances.

Details to gather once everyone is safe

When it is safe and calm, exchange names and phone numbers with the other owner and note the time, place, and what led up to the attack, plus photos of wounds before they are cleaned. If the other dog was loose, repeat-offending, or the owner cannot be identified, report the incident to your local animal control or council service, because a record protects the next dog. Keep your own account factual and prompt; memories of frightening minutes blur quickly, and a same-day written note is worth more than a confident retelling a week later.

Follow-up is part of the treatment

Attack injuries often need a second look: drains checked, wounds reassessed, behaviour watched, because some dogs become reactive on lead after being attacked and benefit from going back to quiet routes and distance-based training while confidence rebuilds. Keep every note, photo, and visit summary together so the pattern is visible at a glance. KinsLe's Pet Passport holds your dog's records in one portable packet, ready for the follow-up vet visit and any questions that come later, instead of relying on memory from a frightening day.
