Hi Jillian-
My pitbull had Malassezia yeast overgrowth as well, due to his food allergies. It was so bad they thought he had demodex mange. Yeast is naturally occuring on the body, however when the immune system is suppressed (as it is with food allergies), the yeast overpopulate because the body is too out of wack to keep it under control. Since doing a food trial through the vet and getting him on a fish and grain based diet, his yeast is gone. I would definitely have a skin scrape done at the vet to determine if it is infact yeast that is causing the smell. Then you need to figure out the primary cause. Each case is individual to the dog and what works for one may not work for another.
