Also known as the Arabian greyhound, the Sloughi's general appearance is described as " a medium-large, short-haired, smooth-coated, athletic sighthound developed  to hunt game such as hare, fox, jackal, gazelle and wild pigs," according to the AKC website.

The AKC describes the Sloughi's attitude as " noble and somewhat aloof." The high-energy dog is considered an ancient breed.

The American Hairless Terrier, as its name suggests, belongs to the terrier group and is the first hairless breed from the U.S.

It is described by the AKC as "a small to medium sized, smoothly muscled and active terrier" and "energetic, alert and curious." Its ancestors were bred to hunt vermin, but today's dog is not as well suited for hunting, since it is hairless.

In a statement, AKC vice president Gina DiNardo said, "We're excited to welcome these two unique breeds into the AKC family. Both breeds make wonderful companions for the right family."

Both breeds require weekly brushing and are considered generally healthy by the AKC.

The Sloughi and American Hairless Terrier became eligible to compete in the AKC Jan. 1.
