Food (or environmental) allergies are especially likely to be implicated in ear problems when both ears are involved. An excess of grain and / or sugar in the diet is one of the most common causes of ear infections in dogs. The sugar actually feeds the yeast which lives naturally in the body and causes a yeast overgrowth, which results in the dark, yeasty-smelling buildup that can occur inside the ears.
One of the first signs that an ear infection is present, is the dog shaking his head and scratching excessively at his ears. Otitis (inflammation of the ear canal) is usually accompanied by redness of the ear flaps. Often the sign of an underlying ear problem can be extremely subtle, such as a very slight tilt of the head, or one ear being held at a slightly different angle than the other. An odor that emanates from the ears is another tell-tale sign.
