The Gordon Setter is a large breed of dog, a member of the setter family that also includes both the better-known Irish Setter and the English Setter. Setter breeds are classified as members of either the Sporting or Gundog Group depending on the national kennel club or council. Life expectancy for the breed is generally about 10 to 12 years. The function of the setter is well summarised by Captain Blaine as follows: ‘The work required of the setter and pointer differs from that of all other breeds of dog. They must search for the body, and not for the foot scent, and be able to maintain a fast steady gallop for long periods without fatigue.
