Puppy Mills Research
Puppy mills are inhumane commercial dog-breeding facilities that may sell puppies in pet stores, online, or directly to the public (in flea markets or via classified ads).
Puppy mills disregard the dogs' health—both physical and emotional—in order to maximize profits.
It is estimated that there are at least 10,000 puppy mills in the U.S. Fewer than 3,000 of these are regulated by the U.S. Department of Agriculture.
The Humane Society of the United States presents the following reports on puppy mills for reference by animal advocates, members of the media, and researchers.
