Puppy mills — large-scale commercial dog breeding operations — cause significant welfare harm through overcrowding, poor veterinary care, and chronic confinement.
Puppy mills represent a systemic welfare failure enabled by weak regulation, consumer demand, and a retail pipeline that obscures the conditions of production. Breeding dogs in mills live in chronic confinement, receive minimal veterinary care, and are bred repeatedly without recovery time. Their puppies, separated early and transported long distances under stress, arrive at pet stores with compromised immune systems and elevated rates of behavioral problems. Legislative reform banning retail puppy sales and requiring adequate standards for commercial breeders, combined with consumer commitment to adopt from shelters or purchase from ethical small breeders, is the path to ending this welfare crisis.
