I am glad you are willing to give her a chance. I would seek a consultation with a veterinary chiropractor and acupuncturist. Trying to get the head of the femur closer into the socket helps in joint formation. I would also use supplements to improve nutritional status. I would try Promaxol to reduce the pain and help healing to begin. Promaxol would be a good choice for your dog. It contains the stronger LM potencies. After improvement is seen then you can switch over to Arthro-IonX. As you see improvement in the comfort level you will want to discuss with your veterinarian about weaning off the conventional drugs while maintaining a good comfort level. Using these prescription drugs is hard on the liver and kidneys , and so is not a good long-term solution.
In addition it is helpful to give digestive enzymes with each meal, MSM, probiotics, Vitamin C, manganese, glucosamine, and fish oil. The oligotherapeutic mineral base found in the IONX products helps the body to better utilize the other nutritional substances given for a synergistic response and faster healing. Also be sure to give sufficient fresh water that is free of chlorine and fluoride. If you can gradually phase into a grain free diet that can be helpful too. Some GMO grains negatively effect the intestinal tract.
