So my mare is on oral regumate - 12 cc/ml a day in am feed. I'm not sure if this has anything to do with the strange behavior but I thought I would mention it. recently, the barn manager and I have noticed that she will curl her tail under her and shrink (for lack of a better word) like a horse will if the hose water is too cold and you spray his/her tail/back area - hopefully I am explaining this well. The thing is, she does this for no apparent reason. Perhaps it is when she is gassy, or after she poops. She did it one day while I was grazing her. Has anyone ever seen or experienced this? Am I explaining it well?n It is really strange, but with the exception of that moment she doesn't seem to be uncomfortable at all.
