Why does my dog stink?

Your dog smells like feet (maybe a little like Frito's?) because of allergies, and quite possibly a yeast infection in the skin. Many dogs have food allergies, commonly to corn, wheat and soy. Be sure his dog food contains none of those. Some dogs are allergic to all grains, and require grain free food. In some cases, dogs are even allergic to chicken, beef, or pork, and require diets free of their allergen protein. You can never completely get rid of fleas, you can only control them. Get some Advantage for your dog and use it monthly during the warm months. Don't bathe your dog more than once every 2-4 weeks, as bathing will further irritate his skin. Have his skin checked by your vet to determine if he has any kind of skin infection that is making the odor worse.
