Terrier is a type of dog rather than one breed. The name comes from the Latin word for earth, because these dogs were developed to chase rats, foxes and other vermin into burrows. Dozens of breeds share the label, from tiny Yorkshire Terriers to the larger Airedale, and listings often use it for terrier-like mixes of Jack Russell, Rat, Cairn, Schnauzer or Chihuahua lines.
Most adoptable terriers are small to medium, typically 10 to 35 pounds, with wiry or smooth coats and a confident outlook. Many are loyal and affectionate, though barking, digging and chasing small animals are common habits. In Salisbury, where raccoons and squirrels share the yards, that chase instinct is worth planning around. A dog's size, coat and energy depend on its ancestry, so meeting a dog says more than the label.
