Query: Dog's Pain Gone with "NEW" DGP from American BioSciences

My "Service Dog"; a 5 year old Plush coated German Shepherd named Wolfgang, who has given me "My life back," needed relief from a sore,and cronic aching shoulder. I researhed, and found many pain relievers, none of which came without precautions and side affects except; "DGP, or Dog Gone Pain. Wolf has been on this wonderful all natural herbal and cartilage joint support and pet revitatization since January 2005. Not only did the DGP releive his pain, but it is giving Wolfie a "new lease on life". We both are so very thankful. We are a team again.
