My bulldog seems itchy more often lately mainly near his tail. I clean daily with witch hazel let dry and put anti itch powder in his tail and folds. But just doesnt seem enough. Past month or so noticed his face stinks and I can wash it and wash it and still stinks. Im thinking he has a allergy problem or a yeast problem. Havent talked to a vet yet but what can I do to help cure this problem? He is on a grain free 4 health dog food and a time or two a day a non grain free treat. Wonder what can I do and maybe what others have done to help their dogs?
