Terrier is a type of dog rather than a single breed, so a Terrier you meet in Sumter is usually a small to medium mix with some Jack Russell, Rat, Cairn, Schnauzer or Chihuahua in the family tree. The name comes from the Latin for earth, since terriers were developed over several centuries to go after vermin underground. Most weigh 10 to 35 pounds, with wiry or smooth coats.
Most are affectionate, confident and quick to learn, with plenty of opinions of their own. Barking, digging and chasing squirrels or cats are common habits, so a secure yard or steady leash walks matter. Because ancestry is often a guess, meeting the dog (and a DNA test, if you want one) says more than the label. Size, coat and energy vary widely.
