When I first got my horse he was completely comfortable with me cleaning his sheath. It seemed to relax him more then anything. Well the last few times he has been very unpleasent. Now when I go to clean his sheath he freaks out and starts to kick out with his back legs. One time it took me 3 hours to clean his sheath and it wasn't even that good! Last time I had the vet sedate Hero to clean his sheath REALLY good. This resulted in him kicking me twice. Once in the chest and another in the knee. Each time he goes to kick I disipline him with a smack.
I think back to when he was actually comfortable with me cleaning his sheath and nothing bad happen to cause him to act like this. He still urinates perfecftly and his actual penis looks fine. It doesn't look swollen or anything. And when he was sedated I did get his sheath cleaned very well and everything. And the next day I tried to just get my hand near his sheath area and he gets all aggravated.
So my question is what could be causing him to be doing this? Could it be a pain thing? If so what are some physical signs I can see that show there may be something wrong with that area?? Or is it just he doesn't like being touched there?
