My RB Buddy took Synovi MSM for several years after my Vet
changed him over from Cosequin DS. I really believe the Cosequin
worked great at strengthening his leg muscle & joints. I did use
the Symovi granules for the last 1 1/2 years with him.

I do think the suppliment should be taken for the rest of their lives. It takes about 6 weeeks to begin to see an improvement
in their health & well being. Best of luck to you & Maggie.
