Have you seen light colored dogs with red stained feet?  Does your dog chew their feet and cause this discoloration?  It could be yeast!  Sometimes a change in diet will help, make sure there is not an excessive amount of corn in their food, check the ingredients on the food.  Corn turns to sugar, yeast loves sugar, yeast will live there happily.
