The Rat Terrier is an American og breed with a rich and varied background as an all-around farm dog. Traditionally more of a type than a breed they share much ancestry with the tough little mixed breed dogs known as 'feists.' Several private associations have maintained Rat Terriers registries for some decades, but more recently there have been movements to obtain breed recognition by the major canine organizations. Common throughout America on family farms in the 1920s and 30s, they are generally considered a rare breed. Today's Rat Terrier is a handsome, intelligent, active little dog that is equally cherished as a farm helper and as a family pet.
