I was just wondering if anyone knew any in-depth information about hock injections/stifle injections. I've ridden tons of horses who have needed them, and I know of many more require them - and I believe that whatever they inject them with honestly works great. However, I was wondering how often horses typically need the injections (lets say, a horse who is being ridden very consistantly and jumping around 3' - 3'6, showing, etc.) and how much each session of injections costs. This is just for research and personal knowledge information, nothing major. Thank you!
