Puppy Mills are very horrible places were female dogs are breeded until they can no longer breed or until they die. After the puppies are born they are caged and barley feed and they have either no water or water with algae. These puppies usually grow a fear of humans and have diseases or tumors, from being improperly bred. These puppies are usually sold to pet stores, where they say their dogs our from licensed breeders but are not, so adopt not shop.
