No Pet Store Puppies Day is a holiday dedicated to raising awareness about the problems with buying puppies from pet stores. Most pet stores that sell puppies get their dogs from puppy mills, where the well being of the puppies and their parents are not taken into consideration on the quest to make a profit. The best way to shut down puppy mills is to get as many people as possible to reject the pet stores that sell these puppies. Do not shop for dogs or other pet supplies there. You can help promote well being of dogs by instead adopting dogs from local shelters.
