1. The dog fingerprints.
Did you know that a dog's snout is unique? The truth is that there are no two identical snouts, as happens with the fingerprints of humans, dogs also have their own brand. Another curious thing is that the color of the nose can change color, either because of a burn or because of the change of weather season. The nose also helps the dog to stay cool. In fact, the longer the snout, the easier it is to eliminate excessive heat.
