People who raise donkeys refer to the babies as "foals." Males are called "jacks," while females are "jennets." Adults of different donkey breeds range in size from fewer than 3 feet to more than 14 hands tall.
Donkeys are useful to humans in many ways. People ride donkeys with saddles and bridles, though donkeys are not always cooperative when instructed where to go. They typically have friendly, gentle natures, and they make good pets for children. Some donkeys are even used as guard animals, watching over herds of cattle, sheep or goats. Donkeys dislike canines, so they go up against predators such as wolves and coyotes. However, this also means that donkeys do not naturally get along with family or farm dogs.
