I've been passing this off as B.S. But I've had so many people tell me this recently. Does hoof color make any difference in the strength of the hoof? Jack has black front hoofs and white back hoofs. I have had people try to tell me that his back hoofs will be prone to problems and I should have shoes put on the back. The farrier comes out again in Feb so I'm not going to call and ask. Any ideas???
