The Rat Terrier is an American dog breed used as all-around farm dog and hunting companion. They come in a variety of coat colors and patterns, and are often mistaken for Jack Russels, even though the Rat Terrier always has a single coat. They range rom about 10 to 20 pounds, and stand 13 to 18 inches at the shoulder.
The Rat Terrier was common in the 1920s and 1930s, but is today considered a rare breed. This is an intelligent and active dog that can also appreciate relaxing in the sofa.
