My horse has recently started licking and chewing on his stall and I am concerned that it will lead to cribbing. I haven't been able to work him a lot lately so I think he is bored. Someone at the my barn said it could be ulsers. Any thoughts?
It may be ulcers. You could try a short course of UG or GG and see if it helps.
It may be boredom, if he's stalled a lot, not getting exercised, doesn't have enough hay in front of him....
You could try that No Chew stuff. I've also heard of people using soap, a mild pepper, anything that tastes nasty that is relatively harmless.
We couldn't all be cowboys, so some of us are clowns.
I have a horse that has licked the stall walls and bars for 14 years now. He has never cribbed.
If he's actually chewing the wood, it's generally considered a phosphorus deficiency.
