Thank you cali. I don't understand why these people are so against breeding a black and tan lab or any other mismark. Its still a quality lab. Some people say they should be spayed or neutered for population reasons, but the breeder could just as well produce as many puppies in black as they could in an "unaccepted" colour. If the puppies are black, yellow, or chocolate than its ok to add to the population, but not if they are another colour? None of the arguements I've seen on this thread are logical.
