One of the best remedies I have found...and was told to use by my holistic vet is a product called DGP. It is all natural. It contains Feverfew which soothes joint discomfort. Celery seed which provides potent anti inflammatory effects...Boswellia serrata which blocks production of inlammation..shark cartilage- a safe, non-toxic dietary source of glycosminoglycans that promote healthy joints....and many other key ingredients.
It can be ordered at 1-800-819-7371 from a company called Harmony.

Massage with Tiger Balm has also helped my older dogs.
