Why do Canines have black noses?

While a majority of dogs have black noses, not all do. The noses of dogs such as vizslas and weimaraners match their coat colors, red and silver, and it is not unusual for puppies of any breed to start out with pink noses that then darken as the animal matures. Some Shetland sheepdogs retain pink on the insides of their nostrils for their entire lives. But most dogs do have black noses and considering that the nose is the only part of their skin that is not completley covered with hair, the skin is pigmented to protect it from the sun. Pigmentation is nature's way of protecting the skin from UV (sun) exposure. So dogs with pink noses are prone to getting cancer meaning if you have a dog with a pink nose you should put a sun block on them
