Dog Aggression: Assessment and Safe Management

Canine aggression is a serious welfare and public safety issue that requires professional assessment and evidence-based behaviour modification rather than punishment.

Key Facts

Most dog aggression is fear-based — dogs bite because they feel threatened, not because they are dominant or vicious
Breed-specific legislation has limited evidence of reducing bite incidents — individual assessment is more effective
Signs of fear and anxiety almost always precede aggressive incidents and are frequently missed by owners
Punishment-based training escalates aggression by increasing fear and suppressing early warning signals
Effective management combines behaviour modification, environmental management, and sometimes anxiolytic medication

Welfare Considerations

Aggressive dogs are suffering dogs. Most cases involve animals in chronic states of anxiety and fear that express through defensive behaviour. The welfare of the dog and the safety of people around it are inseparable — an aggressive dog is at high risk of euthanasia, making behaviour treatment both an animal welfare and a public safety intervention. Dogs should never be managed through flooding, dominance, or punishment — these approaches worsen welfare and behaviour.

What You Can Do

Seek assessment from a certified clinical animal behaviourist if your dog shows any aggressive behaviour
Avoid punishment-based training methods for fearful or aggressive dogs — they make the problem worse
Implement environmental management including muzzle training and controlled social exposures as immediate safety measures
Discuss anxiolytic medication with your vet as an adjunct to behaviour modification for severely anxious dogs
