Information and facts on the anatomy of the dog THE BODY OF A DOG Dogs grow to various sizes. The Irish wolfhound, for example, stands about 32 inches high at the withers, or top of the shoulders. The chihuahua, however, stands about five inches. The color of a dog's coat, or hair cover, also ranges widely, even within a breed.
Some dogs are all black.
Others are all white. Some have light markings on portions of their bodies and darker coloration elsewhere. Or, they may have a solid color other than black. All dogs have some hair cover, even the so-called hairless ones. The size and form of these structures vary greatly as do, for example, coloration and hair characteristics.
