Donkey
While the assumption that donkeys can be very stubborn is true, it’s only because of their strong need for self-preservation. Naturally untrusting of humans, it’s difficult to frighten or convince one into doing something it doesn’t want to or perceives as a threat. Once trust is earned, donkeys are willing to become friendly companions or dependable workers. A donkey’s main means of defense against predators are biting, kicking, or striking.
