If he did have training then he has forgotten it all. We expected a castrated donkey and got a Jack. But he is very well tempered for a jack. We don't have very good fencing but he respected the fence, and he will let you pet him if hes not grumpy. Sometimes he will throw little temper tram-tums and put his ears back and paw the ground while flipping his tail, and after a minuet he will just go in the barn and eat hay. Over all he is an O.K donkey.
