To end the cruel treatment of dogs in mass breeding operations.

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 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.

What are puppy mills?

Inhumane high-volume dog breeding facilities that churn out puppies for profit, ignoring the needs of the pups and their mothers. They commonly sell through internet sales, online classified ads, flea markets and pet stores. 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.
