Cox Vet Lab supplement

I purchased this for a senior mare with arthritis that was limiting her movement. Having used it for a few weeks I am seeing a difference in her activity. She is much more mobile. I will caution that originally I fed with a pelleted feed and she left it behind. When I went back to the textured feed she preferred it mixed in better. Definitely will purchase again.

great product

Started giving ActiFlex Sr. to my 3 old guys a couple months ago. (All are 30+ years old.) I'm seeing them move easier and often working up to fast trots and slow lopes now, which I rarely saw before. Have had these guys since they were 3 and want to make the later days of their lives as comfortable as I can. Great product from a great company that loves horses.

Hopeful it works

Chewy did excellent job getting the horse supplement to me. Will need to see how it works on the 3 seniors using it.

Didn't see improvement

Bought for a 35yr old Shetland and after a tub I saw no improvement in weight or joints. He did shed out easier this year but that's the only positive I noticed.

Best supplement

Best supplement I've tried for my older horse. Has all the ingredients necessary to keep joints working freely.
