Beyond being a farm dog, rat terriers have proven themselves to be a versatile, multipurpose breed with a playful, happy-go-lucky attitude. They are an all-in-one dog able to do virtually anything they are trained to do and they are easily trainable and exceptionally intelligent. They excel in conformation, agility, obedience, rally obedience, terrier racing, earthdog, barn hunt and lure coursing. They are capable of hunting rodents and vermin above and below ground. They make fine therapy and service dogs. And they are loyal friends and companions, especially for families.
