Arthro-IonX can help with old injuries. You may use Arthro-IonX along with other medications or supplements. It is homeopathic in nature, so it will not negatively interact with other physical substances. You can use Rimadyl along with Arthro-IonX to provide comfort while healing is occurring. Healing takes more time than just suppressing symptoms. Arthro-IonX helps to stimulate healing. In addition, I find it helpful to follow a holistic approach by giving some nutritional supplements to accompany Arthro-IonX. The supplements I recommend are Canine Probiotics, MSM, Vitamin C, and Omega 3,6,9. Arthro-IonX will help the body to better utilize the nutrition for a synergistic response. I would also suggest consulting with a veterinary chiropractor. Spinal alignment influences how the limbs function.
