This report is a list of some of the nation’s dog breeding kennels that are of high concern to The HSUS due to repeated problems with animal health or animal care. It is not a list of all puppy mills, nor a list of all problematic facilities. The list does not include other problematic puppy mill dealers, such as brokers and pet stores, unless the operators are also breeding dogs.
