Ever wonder why you see donkeys in with herds of beef cattle?  Donkeys have an inherent sense of protecting their domain (or pasture) from predators like stray dogs or coyotes.  This is especially important if newborn calves are present, as they often times are in beef herds.  So while Sarge here is docile and great with kids, prowling coyotes will turn him into a lean, mean, stompin’ machine.
