Hundreds of thousands of puppies are breed at Puppy Mills, and then sold to Pet Stores. These dogs only job is to breed and have puppies, so the owner can make as much of a profit as possible. If the dogs can no longer breed, then they are very often killed with a metal object beaten against their head. No health care, never enough food, and no medical care, these dogs live in a wire crate their whole life with no socialization, and never able to enjoy the grass and walking. This is no way to live. To stop Puppies Mills, don't buy puppies at Pet Stores.
