Call Customer Care. They have such good knowledge of all the supplements, I’m sure they would be able to help you. You could also combine them. My guy is on a couple similar ones. I am all for preventing the injury, so I would also suggest putting him on a hoof and joint supplement. That being said, SmartCombo has SmartFlex and SmartHoof in it. I would definitely suggest putting him on Ultra if you are going to be doing a lot of competing and work with him, especially during show season (sorry, I event, do you reiners have show seasons?). Also, while he is in that show season and is at the most risk of re-injuring that tendon, I would also suggest putting him on SmartTendon. You can always change up and adjust his SmartPaks whenever you want, don’t forget! Best of luck in your 2014 season!
