I have a five yr. old Jack Russell. He has had surgery on one of his rear legs years ago due to defect in his knee joint. Over the years the best thing other than drugs for the vet to stop the pain and o comfort him was Heat. We moved from Cold Ohio to Naples, Fl. for a few years and he was like a pup again. Laying in the sun and that really helped him a lot. Now due to work we have had to move back to Ohio and the winter is really starting to take it tole on him. Instead of keeping him on meds from the vet we place a heating pad in his bed during the day and really helps him. Believe me, three or four hour of that and he is good to go. Other home made cures other than a good diet just are not going to made much difference. You got a just try the heating pad. It's cheap and it works.
