You’re welcome.
Pretty good article.
As a dog breeder I assume that most things have some genetic component, either directly, or as a predisposition. Not sure about a cracked hoof, but it would be hard to imagine that this horse did not get the best possible hoof care. I wonder if it might not have something to do with weight, the makeup of the hoof, the and something about the way he runs putting more pressure on the hoof. But I’m just yaking, since I’m not any sort of experts on horse anatomy. Wish my father in law as still around, he raised, raised and conditioned thoroughbreds and quarterhorses for racing. I’d love to be able to get his take on all of this.
