You may use ARTHRO-IONX along with other medications or supplements. It is homeopathic in nature and so it will not negatively interact with other physical substances.
To dose ARTHRO-IONX I would split the dose and give a half dose with breakfast and a half dose with supper. It is important to give it away from the prednisone. The prednisone can diminish the response of the homeopathic. In addition I would give PROBIOTICS, OMEGA 3,6,9, and filtered water.
I would recommend having a veterinary chiropractor check your dog. It often improves movement.
Please let us know how you do.
