Border Terriers come from the hill country along the English and Scottish border, where farmers and foxhunters needed a small, tough dog with legs long enough to keep up with horses and a body narrow enough to follow a fox underground. The otter-shaped head and harsh, wiry coat in red, wheaten, grizzle and tan, or blue and tan are the breed's trademarks.
Many Borders are cheerful, affectionate and less quarrelsome than other terriers, but the working instincts remain: chasing, digging and an independent streak. In El Paso, lizards, rabbits and desert burrows give those instincts plenty to work on. The coat sheds low to moderately and stays tidy with hand stripping a few times a year, and the breed is known for living well into its teens.
