>>1982310Some people still use these dogs for their purpose, and breed dogs solely on their ability to perform on the field. As a result, they look leaner, are more athletic, and generally more healthy.
This not only true for labs, but for other working breeds as well (basset hounds, border collies, GSDs, etc). You can find breeders if you look, but they won't usually be affiliated with conformation registries and clubs, so be sure you know how to tell a reputable breeder.
