My family has been on a waiting list for over a year for a black lab puppy. The breeder is very reputable. However, we are being promised a black lab but both parents of the litter were posted and they are both yellow. We have a deposit down and can’t get our deposit back unless they can’t provide a puppy. I have read multiple articles and everything says two yellows can’t make black. We aren’t totally opposed to yellow, more so just feeling we are being promised something that is not possible. Thoughts? Is it possible there could be a black puppy?
