Rat Terriers began as American farm dogs, valued for clearing barns of rats and chasing squirrels. They're compact, smooth-coated and always pied, in miniature and standard sizes, usually weighing 10 to 25 pounds. The short coat sheds moderately year-round and needs only a weekly brush, but it offers little insulation, which matters on Reno's freezing nights.
Many are cheerful, affectionate and eager to stay near their people, and they tend to be more biddable than other terriers. They also bring strong prey drive, quick reflexes and a taste for digging, so secure fencing, a leash and supervision around small pets are part of daily life. Dogs differ, so watch how a Rat Terrier handles excitement, strangers and squirrels before deciding.
