For a long time I have been reading the threads on horses. I have been thinking of getting a horse. I take getting any animal a life long commitment. So I do a lot of studying on the animal before making the commitment. It seems from a lot of posts, the horses stomach is a direct line to health. I have read many warnings about over grazing.Yet all the horses around me are in large fields of grass. They have the ability of eating all day long.Is free pasture really dangerous for a horse?
