Try colloidal silver. The other suggestions for omega 3s and such are also good, as would perhaps many things that are also good for human back and bone conditions (collagen, aloe, MSM, silica, GTF chromium, red clover, glucosamine, chondroitin, calcium, magnesium, boron, etc.) Trust me though - try colloidal silver. You may be quite surprised. It helps regenerate and repair tissue and bones and has played an important role in relieving back and arthritis pain for many. At any rate it will be good for your dogs to take, boosting their immune systems, preventing parvo and many other conditions, eliminating infection and restoring lost energy and mobility.
At first, put at least one ounce in each waterbowl. More if you wish, she cannot overdose and there are no side effects. You can get the colloidal silver from Curezone Sponsor Utopia silver at http://www.utopiasilver.com. First time buyers benefit from a special offer of getting one bottle free for every 8 oz bottle ordered, but you must call to receive this offer. For future orders, put in their coupon code, LR001, and you will receive a 15% discount if it is not on sale.
You will notice that she will be drawn to the water and drink more of it. There are no adverse effects to colloidal silver at all. No side effects and she can drink as much as she wants. For high amounts of colloidal silver, you may want to include probotics to keep the intestinal flora thriving. However, I will point out that when my Misty was ill and I gave her vast amounts of colloidal silver for a fatty tumor, I did not include probotics and she healed rapidly and my 11 year old Misty regained the zest and vigor that she once had as a puppy.
I wish you the very best.

He made home-made ionic silver and contaminated it with salt (resulting in silver chloride) and then not only rubbed it on his face daily but also drank over a quart a day for months on end. If you want to be a Smurff that is a sure fire formula. On the other hand, I am not aware of anyone who ever turned blue from taking properly made and adminstered colloidal silver or ionic silver either. The mainstream medicine crowd and the media they have en thrall loved parading him around to warn people against colloidal silver because it represents a threat to billions of dollars in annual profits made by mainstream antibiotics which are less effective, less safe and far more expensive.
