We’re up in the Adirondacks with our dogs the older of which is past 11 years old (and he’s a big guy). That’s the one on System Saver. He’s been on it since being diagnosed with arthritis a couple of years ago. He and I hiked up a mountain a few hours ago and he still had plenty of energy afterwards. The vet wanted him on Rimadyl. But that stuff is dangerous with prolonged use. So Indy and I are both on System Saver. I got off Celebrex. He has a happier life and I can enjoy him longer. Everybody is happy.
