Human-directed aggression in dogs is a serious welfare concern for dogs and people. Understanding underlying motivation enables effective, welfare-positive management that keeps both dogs and people safe.
Dogs that bite are not inherently dangerous; they are often frightened, in pain, or have learned that bite is the only signal that creates the distance they need. The welfare lens reveals aggression as a communication failure or a symptom of a welfare problem rather than evidence of inherent dangerousness. A dog that has had its warning signals (growling, snapping) punished away is more dangerous, not safer — it has learned that warning is futile and may bite without apparent warning. Welfare-positive management of human-directed aggression involves accurate diagnosis of the underlying motivation, pain investigation, appropriate management to prevent rehearsal of aggression, and reward-based behaviour modification to change the emotional response to triggers.
