The other problem common to allergic dogs is irritated ears. When the ears become irritated they produce too much was in the same way your irritated sinuses produce too much mucous. Now that your dog has waxy irritated ears, they too can become infected with bacteria causing a foul odor. Dogs with irritated ears shake their heads and paw at their ears. Other signs of allergic dogs include areas of hair loss and itchy red skin that could occur almost anywhere on the dog.
Hot spots are areas of intense skin infection that occur as a result of allergic irritated skin.
They become oozy and smelly and they spread very quickly. Allergies are not limited to dogs, cats get them as well. Cats can develop swellings around the mouth and on the lips or chin. They can also develop small wounds that we call granulomas on the face and neck. I even see the occasional cat with waxy and irritated ears caused by their allergies.
