Well, that's sure the rub, ain't it. A vet goes to college for four years, then vet school. So their time is worth more - for equine medicine, at least. So why would anyone want a $100 person to do a $20 job? To be honest, I don't know of any vet who wants to shoe a horse! Farriers have a backbreaking job. I have been lucky that I have had outstanding farriers in my life - and they were **** fine people too. Only one was a dud. Thank God he never did any damage to my horses.... they are easy trims.
I have had two brilliant equine dentists in Maryland, but the fella in Tennessee left the property with a lovely red welt from a rasp across his butt. And counted himself lucky I didn't shove it higher. Again, I think the push is to get a standardized licensing. You can tell who graduated from which hoof trimming school by the way they work.... but in the end all should pass certain standards.
I dunno. I would definitely be interested in seeing more info on this.
