Puppy mills are breeders who force their dogs to produce puppies as fast as they can in order to turn a profit. There is no breeding program, little attention to who the dog goes home with, puppies are usually in poor health and are also poorly socialized. There are always puppies available for sale. Puppy mill operators are in it solely for the profit. They are unable to take care of the sheer number of dogs they have, and as a result, the dogs are typically neglected or even abused.
Many dogs suffer needlessly before finally dying.
Some pet shops are supplied by puppy mill operators. These pet shops thrive from the constant supply of puppies, which in turn allow the puppy mill itself to thrive as well. We can all help put puppy mills out of business. Please don't support businesses that are supplied by puppy mills. If you are looking for a pet of your own and come across what you think is a puppy mill, take notes.
