I would try Arthro-IonX to reduce the pain and help healing to begin. We have heard from another owner that said her dog with Wobblers had improved using 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.) 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. I will pass your question about shipping time on to Customer service. They can answer that better than me.
