I got my puppy at three months old from a breeder. She gave me the registration form to send in. At the time she marked my puppy as black and gold. Now he is almost four months old and he has some blue on his head and creeping down his neck. Should I wait to see what color he turns out before I register him and if so how long should I wait to register him to see if all of his coat turns out blue and gold? Or should I just register him as black and gold?
