The Oldenburg horses "are powerful and beautiful at the same time. These creatures are intelligent and still considered rather warm and gentle. Their main characteristic is their strength, but a potential owner may also be interested in their simple training abilities as well. They can be used for competitions, harness work, and as sport horses" (Horse breeds Info). Oldenburgs are selected to be sound, long-lived, and free of congenital disorders (Wiki).
