Some people keep horses as pets. Today, horses are mostly used for entertainment and sports. They are also still used for work and transportation in some places. Horses are used in equestrianism, which is equine sports such as cross-country, showjumping, dressage, horse polo, rodeo, western pleasure, horsemanship, reining, and halter/showmanship events etc. Showjumping, cross-country and dressage are Olympic sports. "Equus" is the old Latin word for horse.
