You may use ARTHRO-IONX or PROMAXOL to help with symptoms. I usually start with PROMAXOl but you can start with either. If you need to you can give the homeopathic along with a low dose of Rimadyl. Continue to decrease the amount of Rimadyl as you see improvement.
To dose the homeopathic I would split the dose and give a half dose with breakfast and a half dose with supper. You can give another two half doses through out the day as needed. In addition I would give PROBIOTICS, vitamin C, OMEGA 3,6,9 and MSM. What kind of water and food do you give your dog? These can influence joint health too.
I would recommend having a veterinary chiropractor check your dog. It often improves movement. Acupuncture can also be helpful.
Please let us know how you do.,
