I do not know Doc but I share is worries about backyard breeders. I know firsthand what difference you can expect from a dog from a reputable breeder versus a backyard breeder. People who breed dogs to make money and do no genetic testing are not doing the breed a favor and are creating more problems that it's worth. For the record most people think of labs as high energy, hyper and the bigger the better. The breed standard is far from what most backyard breeders are producing and a well bred lab should never be hyper, their tail should look like an otter tail and they should have a slight slope from their front shoulders to their tail. Here is a pic of a well bred lab for reference.
