Julie, not all donkeys have a cross. There is the legend of the cross with the donkey carring Jesus, but its a legend. 99.9% of donkeys that have a dorsal will have a shoulder stripe, even if its only 1" long. In fact..in some breeds of donkeys if they do have a cross the breed is considered not a purebred, as having a cross would show a sign of outcrossing. I am talking about Poitous donkeys,which is a very rare breed and large breed. Almost all donkey do have a cross however, alot of times its just very hard to see it, especially on the blacks or deep chocolate browns. My blue eyed ivory dont have one, but my grays all do. Hope this helps you understand it. AND, we wont laugh at you, this forum is a good place to learn everything we just dont know..and the only way to do that is by asking. So ask away.
