Rat Terrier

The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion. Traditionally more of a type than a breed, they share much ancestry with the tough little mixed-breed dogs known as feists. Common throughout family farms in the 1920s and 1930s, they are generally considered a rare breed. Today's Rat Terrier is an intelligent, active little dog that is kept both for pest control and as a family pet.
