I would get an X-ray and/ or find a veterinary chiropractor. The chiropractor would be the best person to get things in the right position for proper function. You might ask the chiropractor if an X-ray would be helpful to him or her. I would also 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. In addition it is helpful to give Canine Probiotics with each meal, Omega 3,6,9, MSM, and vitamin C daily. (We carry the first two and the other two you can get at a health food store.) If the ligament has been stretched the Ligaplex 1 by Standard Process would also be beneficial. 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.
Please let us know how you progress or if you have any other questions.
