Yep....sounds like your dog has an overgrowth of yeast. Dogs will bite at their feet due to the itching the overgrowth causes. Smell your dog's feet....if they smell bad, then that might be what's wrong. Best to take the dog to the vet for a proper diagnosis. If it turns out that's what it is, try cutting the corn/grain from your dog's diet as it contributes and enhances yeast growth. You can also feed your dog about 1/2 cup of yogurt a day to help keep yeast growth under control.
