Description

The Rat Terrier is a versatile and spunky American farm dog, bred for vermin control and treasured for its loyal nature, lively personality, and work ethic. They’re known for being affectionate with family, playful with kids, and great at agility and obedience.

Their short, sleek coat is low-maintenance, though they do shed moderately, especially during seasonal changes. Brushing a couple times a week helps keep their coat healthy. Rat Terriers are smart, trainable, and love learning, making them a great match for owners who enjoy interactive play, trick training, or dog sports.
