Thoroughbred horse

At the Detroit Zoo
Former racehorses Trio and Buster were rescued by the Communication Alliance to Network Thoroughbred Ex-Racehorses (CANTER) and landed a cushy retirement at the Detroit Zoo in 2009. Many horses are retired from the racing industry each year, but few are as fortunate as Trio and Buster to live the good life in the Zoo's Barnyard along with the belted Galloway steer, Scottish highland steer, miniature donkeys, domestic yak, pigs and other barnyard animals. Trio is a chestnut gelding with white markings on his face and Buster is a bay-colored gelding, that is, the darker of the two.


The Thoroughbred horse is best known for being used in horse racing. It is most often bay, chestnut, seal brown, black or gray in color. The Thoroughbred horse tends to be high-spirited, fast and very athletic.
