Safety first

My dog is aggressive. What do I do right now?

Before any training, safety. These steps can prevent injuries while you arrange professional help.

  1. 1

    Prevent more incidents

    Use baby gates, closed doors, leashes and crates to separate your dog from known triggers: guests, children, other dogs.

  2. 2

    See your veterinarian

    Pain, thyroid problems, neurological conditions and other medical issues can cause or worsen aggression. Ask for a full exam and tell the vet about the behavior.

  3. 3

    Stop punishing

    Yelling, hitting or 'alpha rolls' can make aggression more dangerous and less predictable.

  4. 4

    Write down what happened

    Note triggers, body language, time of day and what happened before and after. This helps professionals.

  5. 5

    Plan for visitors

    Keep your dog behind a closed door or in a crate when guests come. Never leave children unsupervised with a dog showing aggression.

  6. 6

    Arrange professional help

    Look for a veterinary behaviorist or credentialed behavior consultant. See how to choose one.

Breaking up a dog fight

Never reach between fighting dogs with your hands. If you can do so safely, try loud noise, spraying water, throwing a blanket over them, or placing a barrier (a board, a chair) between them. Prevent future fights by separating the dogs and calling a professional.

Equipment that can help

  • A basket muzzle, introduced gradually with treats (see muzzle training)
  • Baby gates and closed doors
  • A secure harness and a strong leash
  • A crate or quiet room your dog enjoys

Management buys time. Training changes the behavior, and a professional should guide it. See our gear guide.
