How much should you rely on a farrier to assess possible hoof problems? I feel as though my farrier is fairly knowledgeable, but I am slightly skeptical on just taking their word for it. Do they typically know how to establish whether or not there is a problem and trim accordingly, or should you rely on vet assessment?
That can be a tricky call. My vet from over 35 years ago gave me grief over my horses being unshod, even though by his own admission they never had foot problems and had good looking feet. He was just certain that I was going to end up with problems. In the end he just concluded that barefoot horses could be ridden safely and without damage. My family was probably the only people in the county that didn't shoe their horses. Wasn't like today, where going unshod is much more accepted.
I won't even mention what the local farriers thought, but we didn't use them, because they just wanted to drive nails into my horse's feet.
Nothing wrong with questioning what the farrier, vet or anyone else tells you (I certainly do). And today, with the wealth of resourses and information at your finger tips (it's a far cry from 30+ years ago) you should be able to check up on just about anything you're told.
