Do cats and dogs have fur or hair?

Answered by James Kissner

Cats and dogs both have fur, which is essentially the same as hair in terms of its composition and function. The term “fur” is commonly used to describe the coat of mammals such as cats and dogs, while “hair” is often used to refer to the covering on the heads of humans and some other mammals.

Fur, like hair, is made up of a protein called keratin, which is produced by specialized cells in the skin called hair follicles. These follicles are embedded in the dermis, the second layer of the skin. The hair follicles go through cycles of growth and rest, which results in the shedding and regrowth of fur. This is why cats and dogs often have periods of heavier shedding, known as “blowing their coat,” where old fur is replaced by new growth.

The appearance and texture of fur can vary greatly between different species and even within the same species. Cats and dogs have different types of fur, which are adapted to their specific needs and environments. For example, cats typically have a dense and soft undercoat, which provides insulation and helps regulate body temperature. They also have longer guard hairs on the surface, which protect the underlying fur and skin.

Dogs, on the other hand, exhibit a wide range of fur types, depending on their breed. Some dogs have a double coat, consisting of a dense undercoat for insulation and longer, coarser guard hairs for protection. This type of fur is commonly seen in breeds like Siberian Huskies or Golden Retrievers. Other dogs may have a single coat, which is typically shorter and less dense.

In terms of function, fur serves several purposes for both cats and dogs. It helps to regulate body temperature by providing insulation against heat and cold. It also acts as a protective barrier, shielding the skin from the environment, such as UV radiation, scratches, and abrasions. Fur can also aid in camouflage, helping animals blend into their surroundings for hunting or avoiding predators.
