Canine aggression is one of the most common reasons dogs are surrendered or euthanised, yet evidence-based rehabilitation programmes achieve lasting improvement in the majority of cases when started early and managed consistently.
Dogs displaying aggression are frequently in chronic states of anxiety, fear, or pain. The welfare cost extends beyond bite incidents to include the dog's subjective distress during everyday interactions. Rehabilitation prioritises reducing the emotional triggers of aggression rather than simply suppressing the behaviour — addressing the root cause improves both safety and the dog's quality of life. Management tools such as head halters and basket muzzles, used humanely, protect all parties while the dog learns new emotional responses. Long-term follow-up and owner education are critical, as relapse is common without continued support.
