We just registered for the Justlabradors.com forum. My wife and I live in central Florida and have two great labs. Sophie is a chocolate and Boomer is a true yellow and they are litter-mates. Boomer is a stud and is available for service. Sophie has been spayed to prevent unwanted breeding with her litter-mate, Boomer. They are both loving and well comported. Interestingly, both their sire and dam were chocolate labs which had yellow, chocolate and black puppies in the litters.
Stay well all.
Two chocolate labs are not genetically capable of producing black puppies when bred together... but welcome to the forum.
