Rat Terriers 101
Terrier groupThe Rat Terrier is the formalization of an old American type of terrier, a scrappy, happy-go-lucky dog with determination and a keen desire to rid the world of vermin – including some that people now keep as pets! This athletic dog is up for any activity and does well in canine sports such as agility. They are typically friendly to all but reserve the largest part of their hearts for their families.
