Canine aggression is rarely random — it is almost always a welfare signal indicating fear, pain, or past trauma. Understanding its causes leads to more compassionate and effective responses.
Canine aggression is almost always a welfare problem before it becomes a public safety problem. Dogs that bite are usually afraid, in pain, or have been pushed beyond their stress tolerance. Treating aggression as a character flaw or dominance behavior leads to punitive responses that increase fear and worsen the underlying welfare problem. Breed-specific legislation punishes dogs and owners for the appearance of breeds rather than actual behavior, causing welfare harms through seizure and euthanasia. A welfare-centered approach identifies the causes of aggression through veterinary examination and behavioral assessment, then addresses those causes through behavior modification and environmental management.
