My eight year old cockapoo had extreme arthritis in her right front leg. The arthritis was so severe that she limped constantly and could not run on all four legs. She no longer chased squirrels which she normally loved to do.
I knew that glucosamine could be used for human joint repair as my brother had used it for his knee. After doing further research on the internet, I decided to give it a try for my dog.
I reviewed the ingredients and recommendations on the Drs. Foster and Smith website before deciding on the Joint Care 3. This level seemed to be what my dog needed as one of her symptons was "Limping at all times" as described on the website.
The Joint Care 3 formula includes chondroitin, and perna mussel which like glucosamine can rebuild cartilage. Other ingredients aid with synthesizing cartilage and joint fluid, decrease inflammation, and to decrease discomfort associated with arthritis.
My dog has been taking Joint Care3 for almost a year and she is like a new dog. She runs, chases squirrels and rabbits and no longer limps or favors her front right leg.
One word of caution about glucasomine is that it can caused elevated cholesterol so dogs should have their level checked by a vet periodically.
