Thanks for responding Tatsxxx11.......since July our problem has been resolved. I think it was just what you said. Those big clumps of hair that don't come out right away just start to stink after awhile. Nikko just had his bi-annual grooming and he is smelling wonderful. He typically never smelled, which is why I had a question in the first place. It must just be when he sheds we have to pay extra attention to all the little clumps to avoid that odor.

Thanks for the replies!
