The black v. pink nose is simply a lack of pigmentation. The breed standard (from various kennel clubs around the world) states that black is preferred. As a rule, no genetic problems are associated with pink noses alone, but throw in blue eyes, liver colored coat, etc and you can have recessive genes that may result in problems down the line. In fourteen years with the breed, I have never seen yellow eyes. Could they be light brown or liver colored eyes? If your dog is otherwise healthy, I would not worry about the nose or eye color and love him for the dog he is! =) Please consider neuter or spay if the dog is of age and in good health, as fortunately these traits are 'rare' as a result of health testing and responsible, selective breeding. I hope everything else is good with your bt! =)
