American Hairless Terriers are descended from Rat Terriers, and they're native to the American South (specifically, they came from Trout, Louisiana in the 1970s). These Terriers are small, standing up to 16 inches at the shoulder.
Despite their name, American Hairless Terriers can have a short coat. But whether they're hairless or not, these dogs require little grooming aside from a brushing once a week, and you'll want to keep the hairless ones away from the hot sun because of sunburns. Likewise, they don't do great in cold weather.
Skin problems are rare, and they're a generally healthy breed. They're active and, because of their small size, generally only need about one cup of food per day. However, these dogs can be hard to find depending on location.
