Dogs of the terrier group have in common the proclivity to kill rodents and vermin, often by digging or going to ground after them. The word terrier, in fact, refers to earth, or terra. Some terriers were developed in part to kill rats in pit contests, and later to fight against each other. The vermin-catching terriers are roughly divided into long-legged and short-legged breeds.
