The "Pony" ponies in Dolmen, western Germany, have survived in the wild since the year 1300, and about 400 horses of this endangered species now live in the area, where they are cared for in a 400-hectare nature reserve that was created by the Duke Croy family. Some still consider this type of horse to be wild because it moves freely and is not subject to any owner, which is what makes Dolmen residents come to see it and specialists attempt to tame it for riding annually. Males are separated from the herd in order to prevent overcrowding in the reserve, and are returned to the herd during the mating season. Horse taming in Dolmen attracts thousands of spectators every year. For more: Sea buffalo learning to swim to achieve its balance Residents of the city of Harar succeed in taming hyenas
