Tri-hist daily. Most of the time she is good, can ride her for miles no problem. Lately its been bad. I have put her in another pasture, with another one of my horses, take some of the hay out of round feeder, shake it out and hose it down with water, so there is no dust. Does anyone know of any other products to use, that would be liquid instead of granual ( I mix tri-hist with apple sauce and use a syringe to orally give it to her) and a different product that works. Talked to a couple vets. Or any other advice on how to care for her. No I am not getting rid of her, just looking for some constructive advice on solutions.
