I would start with PROMAXOL. It helps to decrease pain, inflammation, and stiffness and stimulate healing. Initially I would give a half dose with breakfast and supper. After improvement is seen you can decrease to a
whole dose once daily. For longer term management you can switch to ARTHRO-IONX. However, if you wish you can just start with ARTHRO-IONX. It usually works well from the start. In addition I find it helpful to follow a holistic approach by giving some nutritional supplements to accompany the homeopathic. I would also use Probiotics and Omega 3,6,9 to help reduce inflammation. What type of food and water are you giving? Where do you live?
I would also suggest an evaluation by a veterinary chiropractor. If a correction is needed, that can help with better movement. Looking forward to your reply.
