Breed-specific legislation targeting pit bull type dogs has welfare implications for affected dogs while evidence for its effectiveness in reducing bites is limited.
Breed-specific legislation welfare harms are direct and measurable: dogs seized from responsible owners and euthanized, dogs surrendered to shelters where they face extended stays or death, and dogs kept in restrictive conditions that compromise their behavioral welfare. The evidence that BSL reduces dog bites is absent — communities that repeal BSL in favor of general dangerous dog enforcement do not see bite increases. Welfare-positive dog policy targets behavior and owner responsibility rather than appearance and breed.
