Breed-specific legislation banning certain dog breeds has significant welfare implications. Evidence on its effectiveness and welfare impact informs policy discussions.
Breed-specific legislation causes direct welfare harm to well-socialized, non-aggressive dogs of banned breeds. Seizure and euthanasia of dogs based on physical characteristics rather than behavior causes unnecessary death and family separation. BSL also discourages ownership of banned breeds, meaning these dogs are less likely to be responsibly owned and socialized. The evidence base consistently shows BSL does not reduce bite incidents while imposing significant welfare costs. Behavior-based legislation targeting individual dangerous dogs regardless of breed is both more effective and more welfare-positive.
