In response to concerns about the sources of puppies in New York pet stores, The HSUS’s Investigations unit conducted a hidden-camera investigation of 11 New York pet stores, visited many of their puppy suppliers, and studied interstate puppy shipping documents for more than 100 New York pet stores in all. Our investigation concluded that, regardless of what pet stores’ sales staff tell shoppers about their puppy sources, all of the stores investigated were buying from inhumane mass-breeding facilities known as puppy mills -- including some of the worst known puppy mills in Missouri and other top puppy mill states.
