aw, that's awesome. Horses do do that I have noticed before! We have these two old horses we keep together and one morning one of them was having a belly ache. The other guy was doing the same thing. Seemed he was saying like, "Hello? We need someone over here, he's not feeling so hot!" haha.
I was talking more on the lines of calling an animal communicator about your horse. My friend called in about her horse and the main thing that stuck out to me was that he told her his left front often hurt after being shod. And to tell the farrier that he needed to be more careful with his angles. Well, a few weeks prior to that he was dead lame after a shoeing and we found out because his hoof angles were much too sharp. That was pretty amazing.
Another time was my trainer's beloved horse coliced really bad three yrs ago and they called an animal communicator and he told them somehow ( I don't exactly remember) that he had a growth on his intestines that had looped over another part of the intestine. Anyway, when the vet came out that's exactly what she found. I blew me away. Unfortunately, the poor guy had to go that night. :(
