Terrier describes a group of dogs developed over several centuries to hunt vermin, often by following prey into burrows. The label covers dozens of breeds, from tiny Yorkshire Terriers to the much larger Airedale, and it's also used for small to medium mixes with Jack Russell, Rat, Cairn, Schnauzer or Chihuahua ancestry. Coats range from wiry to smooth, and shedding runs from light to moderate.
Many terriers are affectionate, loyal and full of personality, but barking, digging, chasing small animals and a stubborn streak are common. In Bloomington, where deer wander many neighborhoods, a secure fence and a leash outdoors are the safer choice for a dog with strong prey drive. A dog's size, coat and energy depend on its mix, so spend time with a dog before deciding.
