Thank you! I'd never thought of that. The horse has a weepy eye, too, that I've been cleaning with warm water, that my farrier suggested could be a blocked tear duct, so the vet/dentist may be coming out to check that as well. This gelding was a bit of a rescue. He was given to the people we got him from in very poor condition, and after a month the last owners decided they didn't want a horse anymore, and so sold him. He looks like a new horse, now, gaining a lot of weight and muscle, but the teeth are a definite possibility. There was no telling how long it had been since his hooves had been trimmed, the teeth probably need some attention.
Thank you again!
