I believe that people who are looking to add a furry friend to their family should adopt instead of purchasing pets from a breeder or pet store. Within the last few years puppy mills have been increasingly popular. Many states actually have laws against puppy mills, Michigan does not. The midwest is known for the lack of laws that protect the large breeding of animals. Puppy mills are places where animals are genetically misbread and are living in deplorable conditions. Sadly, a lot of these animals are disease ridden and some don't have the opportunity to live long lives. Many pet stores acquire their animals this way.
Animal shelters and sites like petfinder.com have thousands of animals up for adoption. The animals are healthy and ready for a new forever home. Fostering is also a great aspect of adoption. I personally know a foster family for dogs. They rehabilitate animals and often train them so that they can go to a forever home.
