Tension between dogs and what to do after a fight

Notice earlier tension

Blocking doorways, fixed staring, freezing, hovering over resources, repeated avoidance, displacement and one-sided escalating play can matter even without growling. Watch the whole interaction, who can withdraw and whether a dog repeatedly loses access to resources. Separate early and adjust the setting.

During a fight

Do not put hands between dogs or grab collars near mouths. Bites can be redirected. Call for help; use a solid door, gate or barrier only if you can remain outside biting range. When dogs disengage, secure them well apart if safe. Do not use improvised painful techniques or pull a dog held in another dog’s jaws. No method is guaranteed safe.

Afterwards

Arrange a veterinary check after bites, including apparently small punctures. Keep dogs securely separated; do not immediately “make them friends”. Record triggers and obtain veterinary/qualified behavioural assessment for serious or recurring aggression. Attack and injury guidance · Behavioural help.

Reduce the opportunity for another incident

Close secure doors and organise separate feeding, rest and movement routes. Check that children and visitors understand the separation plan and cannot accidentally open a barrier. Do not stage another encounter to see whether the dogs have recovered or to film their reaction. If you cannot maintain separation safely, call your vet or a qualified behaviour professional for urgent management advice.

Check injuries and record circumstances

Contact a vet after a bite even when only a small puncture is visible; do not probe wounds or let dogs lick each other’s injuries. Breathing difficulty, collapse, severe pain or uncontrolled bleeding needs emergency veterinary help. Human bites need medical advice, with emergency care for severe injury. Record what happened just before the incident, resources present, injuries and previous concerns. Use an existing recording only if it can be obtained without recreating the danger.

Ask for a plan tailored to both dogs

Pain, illness, fear and competition may contribute and cannot be diagnosed from a label such as jealousy or dominance. Arrange veterinary assessment and an appropriately qualified clinical behaviour professional for serious or recurrent aggression. In the UK, check the ABTC practitioner’s role and veterinary-referral requirements; other countries use different arrangements. Management may remain necessary even after progress. Discuss workable, welfare-led options if safe coexistence cannot be maintained; needing help is not a failure.

General guidance, not an individual medical, behavioural or legal assessment. The treating veterinary team’s instructions take priority. Search outcomes, recovery and dog relationships vary. Local services and legal arrangements must be confirmed for the location; procedures here are verified for the labelled UK nations and Republic of Ireland, not assumed to apply elsewhere.

Behaviour support should use humane, reward-based methods. Ask your vet about pain or illness and referral to an appropriately qualified clinical behaviour professional for safety concerns. In the UK, the ABTC register identifies assessed roles; check relevant species, role and referral requirements.
