Puppy mills — high-volume commercial breeding operations — cause significant welfare suffering through overcrowding, disease, poor socialisation, and separation of mothers and puppies. Reform campaigns are gaining ground internationally.
Puppy mills represent a clear case of animal welfare being sacrificed for commercial profit. Breeding dogs spend lives in conditions that deny every welfare need — space to move, social interaction, veterinary care, and opportunities to express natural behaviour. Customers who purchase mill puppies unknowingly fund this suffering and often inherit dogs with severe health and behavioural problems. The most effective consumer action is to adopt from shelters or buy only from reputable breeders who allow home visits and demonstrate proper care for breeding animals and puppies.
