Hi Smokey,
It sounds like your horse's problem is very simple -- He's Hungry.
He needs to have hay in front of him all day -- going for hours is very stressful, both physically and mentally. Hay allows his digestive tract to move normally. And, his stomach releases acid 24 hours a day, so that acid is flowing down his digestive tract, leading to ulcers and the destruction of the bacteria living in his hind gut. This is very uncomfortable and even painful.
Don't give him antacids. Feed him. Chewing produes saliva, a natural antacid.
So, the fix is simple -- he is upset and his digestive tract is rebelling because the poor fellow needs something to eat.
I hope this is helpful for you and your horse.
Wishing you the best this holiday season,
Dr. Getty
