A bite changes the risk
Has your dog bitten you or someone in the household?
Prevent another incident first. Then record what happened before, during and after the bite so the next step is based on the real trigger and level of risk.
What to do now
Create safety without escalating the dog.
Move away calmly and use a secure door, gate or familiar separation. Do not corner, grab or punish the dog after the event. Attend to the injury and seek medical help where needed, especially for punctures, deep wounds, bites to the face or hand, heavy bleeding, infection risk or any serious concern.
If the behaviour is new or out of character, arrange a veterinary check. Pain, illness and physical discomfort can change how a dog responds to touch, movement or pressure.
Write down the details while they are fresh.
Include who was present, what happened in the minute before the bite, where the dog was, whether food, toys, resting, handling or restraint were involved, the dog's body language, contact made and how quickly the dog recovered.
Do not recreate the situation for a video. Existing safe footage can help, but a clear written account is enough to start.
