Ugh, puppy mills. These commercial breeding facilities are horrendous. The animals are kept in tiny wire cages, with little to no human interaction throughout their lives. They are rarely, if ever, seen medically and are forced to breed over and over again and watch as their babies are taken away from them and sold to pet stores. It is a supply-and-demand business, so the more people stop going to pet stores and choose to adopt instead, the quicker we can put an end to these puppy mills.
