Trakehner is a horse breed. It is the purest of the warmblood breeds, due to the fact that it is the only warmblood breed that has a closed stud book. The Trakehner is generally of a lighter type than most other warmbloods.
The Trakehner typically stands between 15.2-17 hands high. Trakehners can be any color, with bay, gray, chestnut and black being the most common, though the breed also includes roan and tobiano pinto horses.
It is considered to be the lightest and most refined of the warmbloods, due to its closed studbook which allows entry of only Trakehner, Thoroughbred, and Arabian lines. Wikipedia, the free encyclopedia.
