Im needing help with a problem that occured today when I went to see my horse. He had been stuck in a stable for most his life and basically beeen abandoned so I've taken him on loan and brought him closer to me and is now grazing in a field. He's in a field where theres hardly any grass so his laminitis doesnt come back but today when I went to visit him his stomoch started making funny noises and his droppings are quite runny. I thought his stomoch may be upset as he hasnt been grazing for quite a few years?? Can anyone give me advice or what may be wrong with my horse?
