Donkeys have spread all over the world, with different breeds adapted to various climates and terrains. Some common breeds of donkeys include the African Wild Ass, the Nubian Ass, and the American Mammoth Jackstock. In modern times, donkeys are still used for agricultural work in many parts of the world, especially in developing countries. They are also used for recreational purposes, such as donkey rides and donkey shows. Unfortunately, donkeys have often been mistreated and exploited throughout history. They have sometimes been overworked, underfed, and subjected to harsh conditions.
