The Smooth Fox Terrier is a high-energy breed with the stamina of a working hunting dog. Plan for at least one to two hours of vigorous exercise per day, including brisk walks, fetch sessions, and free running in a securely fenced yard. Off-leash exercise outside enclosed areas is not safe — the breed has a powerful prey drive and will bolt after squirrels, rabbits, and other small animals with complete disregard for traffic or commands. The Smooth Fox Terrier participates competitively in earthdog trials, agility, and conformation events sanctioned by the American Fox Terrier Club (AFTC).
