Terrier is a type of dog rather than a single breed. The name comes from the Latin terra, meaning earth, because these dogs were developed to hunt rats, foxes and other vermin, often by going underground after them. Dozens of breeds share the label, and adoption listings often use it for small to medium mixes with wiry or smooth coats.
Most are lively, loyal and confident, with a talent for barking, digging and chasing squirrels. In Johnson City, that means a sturdy leash, a dig-proof fence and a plan for the neighbors, since city code treats continuous barking as a nuisance. A dog's size, coat and energy depend on its mix, so spending time with the dog tells you more than the label does.
