I have just bred my labrador with another lab, both dogs are yellow labs but the puppies have come out black and brown is this possible.

It's very possible. I think that yellow is a less common color with black being the most prevalent.

Not according to known genetics. Yellow is recessive. Two yellows can't produce anything except yellows. Black is dominant and can carry genes for both the proper term is chocolate and yellow. How carefully did you confine the female after the breeding? A female will continue to breed with any male she has a chance. The male she is known to have mated with, may or may not have sired any of the puppies. Who knows where the black and chocolate genes came from. It could have even been a Lab cross. I don't feel it would be ethical to sell any of the puppies as pure breds.

You really need to do some serious study before doing any more breeding. Start with a good book such as Successful Dog Breeding, by Chris Walkowicz, DMV. Also go to American Kennel Club - akc.org and read their recommendations on breeding. If you haven't learned about how the colors work, I wonder if you did your homework on things like hips, eyes, allergies, temperament, etc. There is a lot more to producing quality puppies than putting a female in her fertile time with a male. We already have an excess of dogs. Go to Petfinder.com: Adopt a pet and help an animal shelter rescue a puppy or kitten. and see how many Labs and Lab crosses will be killed soon if they don't find homes.

My answer is based on several sources including the training sessions of a dog guide school that has been breeding hundreds of Labs for over 20 years. I would like to know what Tonyj bases disagreeing with me on other than spite? People should respect highly trained experts.
