There are hundreds of puppy mills in the U.S and we have to take a stand to end them. The puppies from puppy mills goes to animal stores and are sold. Most of the times the puppies that come from puppy mills have serious problems, like behavioral problems and health problems. When buying a dog from a pet store people do not know that and sooner or later end up taking the dogs to a animal shelter. If there are no more puppy mills there will be less animal in animal shelters, and less homeless dogs etc.
