They appear to be different lengths, but that could just be the photo. They also appear flared and long. But from the sound so it your new farrier got that all "tidied up".
My mare will half pass quite beautifully as an "I don't want to do this anymore!" protest to arena work - no hoof problems. She prefers the trail.
Glad to hear he's doing better, Terri. Sounds like the new farrier might have him straightened out.
I did want to touch on the "low nail holes" thing. That is sometimes a result of the shoe. For some reason, when a horse is shod with St. Croix Forge shoes, the nails seem to come out lower than if they are shod with, say, Kerckhaert. Those are the main 2 brands I've had on my horses and it's obvious which is on the hoof without even picking it up because there will be up to a half inch difference in where the nails come out.
The reason we use both is because their sizes are about a half size different. So, if a horse is just a little bit too big for a 1 in SCF, he'll fit a 1 in the K perfectly. That way, we've always got a shoe that is the perfect size LOL.
My shod arab tightrope walks in front when his (1) toes are long (heels start to run under) and (2) his inside hoof grows faster/wears slower than the outside, causing one of his legs to appear a little pigeon-toed. He has two very different front feet. I am constantly searching for a farrier who can help me with this problem... I have a horse who walks straight after a trim, and 4 weeks later returns to the tightrope walking. Is this at all similar to your issue?
Honestly he hasn't been walking straight even after a trim. Very weird. He still isn't 100% yet, but he's better. I will keep you posted.
I wonder if it's a conformation issu.
