Breed-specific legislation (BSL) targets certain dog breeds as inherently dangerous, but evidence shows it is ineffective at reducing bites while creating significant welfare harm for affected dogs and owners.
Breed-specific legislation creates welfare harms that are both direct and well-documented. Dogs identified as prohibited breeds — regardless of their individual temperament or history — may face mandatory euthanasia, indefinite kenneling, or confiscation from caring owners. Extended kenneling in animal control facilities causes behavioral deterioration, stress, and reduced adoptability. Puppies born during the period of confiscation may be euthanized without recourse. These welfare costs are imposed without demonstrated public safety benefit: the evidence consistently shows that BSL does not reduce dog bite incidents. Owner-focused legislation — emphasizing socialization, training, responsible ownership, and leash laws — achieves bite reduction without the welfare costs of breed targeting.
