I think Arthro-IonX would be helpful to your dog. Arthro-IonX offers pain relief but also stimulates healing. You may give it concurrently with the other medication. As you begin to see improvement you can try to decrease the amount of the other medication because it puts more stress on the liver and kidneys than what the homeopathics would. In addition I find it synergistic to give digestive enzymes with meals, probiotics, MSM, and fish oil. The oligotherapeutic mineral base in the iONX products helps the body to better utilize the supplements for faster results. The natural products work very well together and can offer much relief. Many pets have responded very favorably to this approach. Please let us know how you do or if you have any other questions.
