Its possible the pup will be a patterned sable which means a saddle on the back basically. HOWEVER, if you went through a reputable breeder and told them what you were looking for in your pup personality and temperment wise, its also likely that the breeder is picking out the pup that best fits the personality and temperment requirements you laid out. Color should be the last thing you are looking for. Thats not to say you cant get the total package you want but that could take a while.
