I used Dasequin for Sugar when her arthritis got really bad, plus she had some spinal problems. It did help, but for several years before it got so bad, I used Springtime's Joint Health and Fresh Factors. I use them now for Fletcher and give them to the girls as well, even though they don't have arthritis (yet...). I also give Fletcher a Traumeel tablet twice a day, and a milk thistle capsule once a day. Considering adding S.O.D. and Boswellia. The Greyhound Gang products are great, and very reasonably priced, but my guys don't like the powder mixed with their food
