Underfur

Coat is the nature and quality of a mammal's pelage. It is important to the animal fancy in the judging of the animal, particularly at conformation dog shows, cat shows and horse shows. It may also be used as a standard to evaluate the quality of care and management used by the animal handler, such as in horse showmanship.

The pelage of a show animal may be divided into different types of hair, fur or wool with a texture ranging from downy to spiky. In addition, the animal may be single-coated or may have a number of coats, such as an undercoat and a topcoat (made up of guard hairs (also called an outer coat or, sometimes, overcoat). The state of the coat is considered an indication of the animal's breeding and health.

Animals might have different coat quality for different seasons. Normally, animals with fur or hair body coats may develop a thicker and/or longer winter coat in colder times of the year, which will shed out to a shorter, sleeker, summer coat as the days lengthen into spring and summer. This process may not occur in a noticeable fashion in climates that are warm year-round, though animals may nonetheless shed their coats periodically. The process may also be minimized by artificially keeping the animal blanketed, or, in the case of small animals, housed indoors.

Pinnipeds and polar bears have longer guard hairs forming the most visible fur; polar bears' guard hairs are hollow.

Coat (also known as a rug or blanket) may also refer to a covering or garment made by humans to protect their pets from the elements.
