OP…I feel your pain. I have a QH with TB’y type feet. I have been told for the longest time “it’s just the way he is”. It’s maddening. I’ve cycled through a handful of CJF…all seemingly qualified. But I’ll be candid, it’s SO HARD. Right now I’m hauling my horse 2 hours away to a farrier every 4 weeks, who has put him in pour in pads with steel shoes. It’s completely changed his hoof, and he’s finally getting nice sole depth (he had leather pads on a few years ago, recommended by our vet, and those combined with winter mud wrecked his feet and thinned out his soles). I had a conversation with my current farrier about finding one closer to me that would be competent with my horse, but we aren’t coming up with many options. They just all seem to let that toe grow out. I don’t have any good answers for you, except to say it’s really hard to find the right farrier, but it does make a big difference once you find one. My last farrier was even a super popular “rehab type” that worked out of a local vet clinic - he’s the “go to guru” for problem horses, but even with him, I was struggling by the end of our cycle. He would chop toe off, but that wasn’t the complete answer. It’s so frustrating when you’re using “qualified” folks, doing what you can, but it just doesn’t work.
My only thought is if your horse wearing aluminum, you may want to consider steel shoes…they will absorb more concussion and help hold the foot together a little better.
Good luck. It’s so hard. Again, you’re not alone if you’re discouraged.
