just to give everyone a little update. Dio has been doing very well on the Grizzly Fish oil and vitamin e. His coat is gorgeous, not shedding as much, and I do notice a difference in his hips. He doesn't seem to get as stiff as he was before. A little more pep in his step. after seeing these results in just a month I will def be keeping him on this regimen. Thank you everyone for your help.
