Dog with IVDD and arthritis

Hi Hv
My friend has a 10 y old dog with IVDD and had a mild/mod disc extrusion. It also has pretty bad Arthritis in its elbows and shoulders. Right now she is on tramadol (a pain med) and prednisone. She wants to take a more natural route for treatment. I recommended your bone and joint formula but am not sure if it can be taken with the prednisone. Do you think she should finish the course of the pred? She has also tried acupuncture, but hasn't seen the greatest improvement yet. She isn't very ambulatory because of the pain. She has very mild neurological deficits.
Any advice would be very appreciated,
Thank you Tweet
