This older dog's dewclaw is rounded from use while running, but it has grown.thumb|Some active dogs' dewclaws make more frequent contact with the ground while running, so they wear down naturally, as do their other claws.

The rhinarium (Neo-Latin, "belonging to the nose"; : rhinaria) is the furless skin surface surrounding the external openings of the nostrils in many mammals. Commonly it is referred to as the tip of the snout, and breeders of cats and dogs sometimes use the term nose leather. Informally, it may be called a "truffle", "wet snout," or "wet nose” because its surface is moist in some species: for example, healthy dogs and cats.
