Terrier is a type of dog rather than a single breed. The name comes from the Latin for earth, since these dogs were developed over several centuries to hunt rats and foxes, often by going into burrows. Dozens of breeds share the label, and many adoptable terriers are mixes of Jack Russell, Rat, Cairn or Schnauzer lines.
Most are small to medium, roughly 10 to 35 pounds, with wiry or smooth coats and a lively, confident outlook. They're often affectionate and loyal, but barking, digging and chasing small animals come with the territory. In Amarillo, that means a secure fence, a plan for windy winter days and training that keeps a clever dog busy. A dog's size, coat and energy vary, so a vet visit after adoption helps you plan.
