Our guide to human directed aggression can help you recognize aggression, identify the cause, and provide tips to manage it.

The most common cause of aggression towards people is fear, however there can be other triggers such as resource guarding (protecting food or a favourite toy) or touch sensitivity. We offer guides for managing each situation:

• Managing Fear in Dogs
• Touch Sensitivity
• Resource Guarding

If your dog’s aggression only happens when on leash, check out our leash reactivity resources.

While working with your dog on their behaviour, getting them comfortable with a muzzle will help keep everyone safe in the meantime.

A muzzle is especially useful if they are only showing aggression in certain situations where they may encounter an animal, like on a walk or trip to the vet.

For more information, read our guide on muzzle use and training.

By understanding dog body language and teaching kids how to approach dogs, you can set up safe, positive interactions between them. Below are some resources we recommend for learning more about how to do this:

• Read EHS’ Guide About Child-Dog Interactions
• Watch the following videos:
  • Show Your Kids How to Be SAFE Around Known Dogs
  • Show Your Kids How to Be SAFE Around Strange Dogs

‘Mouthing’ is a common behaviour in puppies as they explore the world with their teeth, chew, and learn how to get attention.

Puppies need to be taught what is okay to chew and how to get attention while young, so it does not become biting as they get older and stronger.

For more information, read our guide on puppy mouthing.

If your dog’s behaviour has changed, they should be taken to a veterinarian.

A sudden change in behaviour can be a sign of a health issue or pain.

In some cases, a veterinarian may also prescribe behaviour medication to help modify their behaviour and/or reduce anxiety and stress.

You can find a veterinary clinic in your area using the ABVMA Directory.

Aggression is a difficult behaviour to deal with. While in some cases it can be managed by avoiding what triggers the aggression, there is always a risk as it cannot be ‘cured’.

Dogs with a history of aggression tend to fall back on that behaviour as a way to deal with stressful situations.

Pet guardians are responsible for their pet’s behaviour and must take precautions to prevent harm to others.

If you are unsure their aggression can be managed in their current environment, speak with your veterinarian to evaluate their quality of life and contact us or your local shelter to evaluate rehoming options.
