donkey

A sure footed graceful member of the horse family. Donkeys are oft thought to be stubborn but are smart and loving creatures. They excel at this such as jumping and carting but are not as good for western riding as speed is not on their side.

Travis: wow look at that girl jumping that pretty grey horse!
boy: That is a donkey dumb arse! They are more sure footed and are easy to train.
Travis: WOW! that donkey sure moves in an angelic manor.
