I know ACV has a ton of health benefits but I cannot find anything about giving it to a horse that is prone to ulcers. Does anyone know if it would help or the opposite, cause a flare up? I used to give it to all 3 of my horses but then over winter I had to stop because it kept freezing. In around February I discovered my TB had ulcers and I haven't given it to her since because I'm unsure if it would cause them to come back. She gets them very easily, something ate her ulcer supplement and she was off it for about a week and during that week she had a flare up. Usually 2-4 weeks of rantidine has her feeling good again.
