In puppy mills, mother dogs spend their entire lives in cramped cages with little to no personal attention. When the mother and father dogs can no longer breed, they are abandoned or killed. Due to poor sanitation, overbreeding and a lack of preventive veterinary care, the puppies from puppy mills frequently suffer from a variety of health issues, creating heartbreaking challenges for families who should be enjoying the delights of adopting a new family member.
The Horrible Hundred is a list of known, problematic puppy breeding and/or puppy brokering facilities, released annually by the Humane Society of the United States, in an effort to inform the public about common, recurring problems at puppy mills.
Puppy mills are inhumane high-volume dog breeding facilities that churn out puppies for profit, ignoring the needs of the pups and their mothers. Dogs from puppy mills are often sick and unsocialized. Puppy mills commonly sell through internet sales, online classified ads, flea markets and pet stores. In fact, the majority of puppies sold in pet stores and online are from puppy mills. Responsible breeders will be happy to meet you in person and show you where the puppy was born and raised—and where their mom lives too.
