We've had a few threads on glucosamine and chondroitin already and it seems from previous threads that many of us give our dogs both of these supplements. I noticed after a couple months of giving them to her that she was a little more active around the yard, running and bucking around. We used to give her the pill form (you can get them at any pharmacy) at 1500mg/1200mg dosage, but we found it more economical to get a powder form on KvVetSupply.co m now that we're giving her a 3000mg/2400mg dosage. The website actually has some great choices on glucosamine and chondroitin supplements, so that would be a good place to browse around.
