Dog aggression is a welfare problem for both the dog and those around it. Understanding causes and evidence-based interventions is essential for improving outcomes.
Dog aggression welfare is a two-sided problem: the dog is usually suffering from fear, pain, or unmet needs that drive aggressive communication, while the human recipients of aggression may be injured. Punishment-based approaches to treating aggression are not only ineffective but actively harmful to the dog's welfare - they increase fear and suppress warning signals (growling, snapping) that serve as communication before a bite. A dog that has been punished for growling will bite without warning. The welfare-positive approach is behaviour modification by a qualified behaviourist (CCAB or ABTC registered), combined with veterinary assessment for pain conditions, and positive reinforcement training throughout. This improves both dog welfare and public safety.
