Puppy mills
It's time to end the cruel treatment of dogs in mass breeding operations.
The problem with puppy mills
In puppy mills, mother dogs spend their entire lives in cramped cages with little to no personal attention. 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.
10,000

500,000

2.6 Million

are sold each year after originating from a puppy mill
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.
Our work around the world
We're fighting to stop puppy mills on all possible levels, including supporting legislative changes, conducting investigations and litigation and promoting public awareness and education.
Working with local counsel, our Animal Protection Law team has assisted plaintiffs in lawsuits seeking to hold pet stores accountable for the harm they cause to animals and to their unwitting customers.
Amanda LoCoco, research program manager for our Stop Puppy Mills campaign, discusses how her work reviewing consumer complaints and breeder inspection reports is all in service of making a more humane world for dogs.
Some of the findings of our latest Horrible Hundred report sound like scenes from horror films. One breeder was associated with the American Kennel Club, a purebred dog registry organization that used to call itself “the dog’s champion.”
Since we first started publishing our Horrible Hundred report on problem puppy mills in 2013, at least 2,500 animals have been rescued from these bad breeders, and more than 250 puppy mills from our reports have closed.
In March this year, our Animal Rescue Team arrived at two properties in Milburn, Oklahoma, to assist the Johnston County Sheriff’s Office with an alleged animal cruelty situation.
The Humane Society of the United States joins Hoosier animal shelters, rescues and local governments in strongly opposing HB 1412.
