Izzy had developed a crack up the front of his hoof, but I knew it would grow out with good farrier work. While Izzy was with the "leg wrecker" trainer (start here and scroll back to find the beginning), I had her farrier shoe him because he was starting to get footsore (he was barefoot). It was a fairly mediocre shoe job at best.
My current farrier has been working with my horses for almost a year, and both of their hooves look really great. Speedy has been able to go barefoot, which I love (no more lost shoes), and Izzy only needs to be shod in front.
My farrier was out this week. I forgot to take pictures of Speedy's toes, but I did get some shots of Izzy's freshly shod feet. They have really changed shape over the past year and look like they are now an excellent weight bearing structure.
