Terrier is a type rather than a single breed. These dogs were developed over several centuries to hunt vermin, often by following prey underground, and that history explains the quick minds and stubborn streak. Listings use the label for small to medium dogs, often mixes with Jack Russell, Rat, Cairn or Schnauzer ancestry, with coats that run from wiry to smooth.
In Reno, that energy suits a city with a river path, fenced dog parks and mountain trailheads. Terriers usually bond closely with their people and notice everything, which makes them good alert dogs and sometimes noisy ones. Because ancestry varies, weight can run from about 10 to 35 pounds, and exercise needs vary with it. Meeting a dog and watching how it behaves will tell you more than the label.
