We were pleasantly surprised to learn after getting goats that they're just as trainable as dogs. In this video, young goats Riggs and Fern play fetch, fighting to be the first to get the ball in the bucket to earn the treat.
Other tricks they learned include "wave", "shake", "jump", "spin", "spin other way", "stay", "back up", "circle" (they run around you), jumping through a hula hoop, and - of course - causing general chaos.
