Tucker is starting to show signs of arthritis. He is 8 years old now and he is being more cautious when jumping off things (couch, bed, etc.) He also shows signs that one of his back legs is sore after he has been inactive for a while. After he walks on it a bit he is fine. I was wondering if anyone knows of a good joint supplement that they use? There is so much out there so it is hard to know what you are getting. Our previous dogs had arthritis really bad so they were on derramax but we want to avoid that stuff because it is real hard on them. Anyway, any suggestions on what to use?
