Right now I am looking for a good joint supplement for my horse. He is a 17 year old Qh who has begun to get a little stiff with arthritis, mainly in his back legs. He is used as a lesson horse 3 or 4 days a week doing w/t/c and sometimes a little jumping for about an hour or so each day, and I ride him some days as well, mainly trail riding but sometimes doing a few jumps.
Are there any exercises, stretches, or warm ups that would specifically help him loosen up and be more comfortable? He is currently being warmed up just doing w/t/c, nothing special. He is outside 24/7 except to be fed, he has free choice hay but does not stand around too much and is usually walking around grazing. He doesn't stock up or anything, just gets a little stiff.
What ingredients should I be looking for in a supplement? If anyone has any that they have used and like or don't like, please let me know. I am looking for something a little on the cheaper side, but something that works well.
Thanks in advance! :)
