Terrier is a type of dog rather than a single breed. The name comes from the Latin word for earth, because these dogs were developed over several centuries to chase vermin into burrows. The label covers everything from tiny Yorkshire Terriers to the much larger Airedale, and adoption listings often use it for small to medium mixes with Jack Russell, Rat, Cairn or Schnauzer ancestry.
In Fall River, hilly sidewalks and mill-town streets suit a sturdy small dog with plenty of stamina. Most terriers are loyal, lively and opinionated, with wiry or smooth coats. Barking, digging and chasing squirrels are common habits, and so is a stubborn streak. Reward-based training and a secure harness help. A dog's ancestry is often a guess, so judge the dog in front of you.
