Fur

For alternative meanings, see Fur (disambiguation).

A dog's fur usually consists of longer, stiffer, guard hairs—which can be straight, wiry, or wavy, and of various lengths, hiding a soft, short-haired undercoat.

The term fur refers to the body hair of non-human mammals also known as the pelage (like the term plumage in birds). Fur comes from the coats of animals; the animal's coat may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Not all mammals have fur; animals without fur may be referred to as "naked", as in The Naked Ape and naked mole rat.

Fur usually consists of two main layers:

• Ground hair or underfur — the bottom layer consisting of wool hairs which tend to be shorter, flattened, curly and denser than the top layer.
• Guard hair — the top layer consisting of longer straight shafts of hair that stick out through the underfur. This is usually the visible layer for most mammals and contains most of the pigmentation.
