Puppy farming - the intensive breeding of puppies for sale - causes significant welfare harm to breeding dogs and puppies, with lasting effects on purchased animals' behaviour and health.
Puppy farming welfare harm operates at two levels: the breeding dogs kept in intensive conditions for their reproductive lives, and the puppies produced who suffer from inadequate socialisation and early separation. Breeding dogs in commercial puppy farms are frequently kept in bare kennels, given minimal veterinary care, and bred at every opportunity until productivity declines, at which point they are discarded. Puppies reared without adequate human socialisation in the critical developmental window develop fearfulness, anxiety, and aggression that persists throughout their lives. Lucy's Law closed one direct sale route, but online sales continue to obscure supply chains. The most effective consumer protection is simple: always see the puppy with its mother in the environment where it was reared before purchasing.
