Q:Please help. No matter who we talk to we can't seem to figure out what's going on with my daughter's 14-year-old American Saddlebred gelding. He is losing weight, but he is eating everything in sight, and as of last week he started scraping his teeth on the bars and boards of his stall, which he has never done before.

About two months ago we moved him to a new barn. The main difference in this barn is that he can have some contact with the horses on both sides of him. He doesn't get turned out at all, as he is a show horse and he doesn't like to be outside. My daughter only rides him about a half-hour every other day, so it's not a hard workout for him.

We have had him tested for insulin resistance, and results came back as borderline, so we changed his feed from receiving two scoops of Strategy twice daily, along with free-choice hay, to one scoop at each meal and only two flakes of hay. That's when I noticed he started to lose weight.

So my question is what could be causing him to lose weight so rapidly, and why is he scraping his teeth on the boards? We really need some help here. We've talked to our vet, and he seems to be just as baffled about it as we are. Could the scraping of the teeth be that he's just bored or needs his teeth floated, or that he's missing my daughter? And as for the drastic weight loss, I'm just thinking he needs to be fed more
