Commercial puppy mills confine breeding dogs in overcrowded conditions with minimal veterinary care, causing chronic suffering for parent dogs and health problems in puppies sold to unsuspecting buyers.
Breeding dogs in puppy mills endure years of confinement, repeated pregnancies, and social deprivation before being discarded when no longer productive. The welfare compromise extends to puppies who receive inadequate socialization, leading to behavioral problems and increased disease rates. The industry profits from consumer ignorance about the source of pet store puppies.
