How commercial puppy mills cause widespread welfare suffering and what legislative and consumer approaches are reducing their impact.
Puppy mills represent one of the most severe companion animal welfare failures at scale. Breeding dogs are confined to wire cages for years with minimal human interaction, veterinary care, or exercise. The psychological and physical damage is profound — dogs rescued from mills frequently require extensive rehabilitation. Consumer demand drives the industry, making purchasing decisions a powerful welfare lever. Legislation banning pet store sale of mill puppies combined with public education about responsible breeder identification is shifting the market toward more welfare-positive alternatives.
