DOGS, CATS AND EAR IRRITATION
The normal ears of dogs and cats have a relatively smooth inner lining with a minimal amount
of wax build up. There can be several things which will cause the ear canal to become filled
with odoiferous debris. Your dog or cat will probably tell you its ears are uncomfortable by
excessive scratching and head shaking. Early treatment of any ear problems is important to
prevent complications such as damage to the inner ear and hearing loss.

EAR MITES: (Otodectes) are a common cause of ear irritation and frequent ear scratching in
cats. Ears infected with these mites are often filled with dark brown, flaky debris. The mites
can be seen when the debris is examined under a microscope.
Allergies are another common cause of ear irritation in dogs. Allergies can be caused by
pollens, molds, plants, fleas and a whole variety of other substances. In addition to
scratching their ears, dogs with allergies often lick their feet and rub their face.
Trauma to the ear from foreign objects, such as plant seeds or burrs, or from aggressive
cleaning with cotton tipped applicators can also cause pain and inflammation in dogs and cats
ears.
Any one of these conditions, if left untreated, can lead to additional and more complicated
problems, such as yeast or bacterial infections. These infectious agents grow best in warm,
humid ears that have little air flow. Thus, breeds that have very long or very narrow ear
canals, animals that enjoy swimming, and those that live in hot, humid environments will be
predisposed to ear infections.
YEAST: (Malassezia pachydermatitis) is a normal inhabitant of the ear in small numbers.
Inflammation of the ear, from any of the above causes, allows the yeast to grow in
excessive numbers. Yeast infected ears have a smelly waxy buildup. Bacterial infections
can result in smelly pus like drainage from the ear and can be extremely painful.
Your veterinarian can examine your pet's ear canal; test a sample of the discharge for
bacteria, yeast, or mites; and choose the most effective treatment. Your veterinarian can
show you the proper way to clean and medicate the ears.
To prevent ear problems, keep your pet's ears clean and dry. It is more important to check
your pet's ears regularly for dirt and discharge than it is to clean them. Look in your pet's
ears once a week or whenever you are petting it. Should they need cleaning, use only
products and methods recommended by your veterinarian. Never clean with a
cotton tipped applicator any deeper than you can see. Finally, if your pet's ears require
frequent cleaning, see your veterinarian and treat the cause before complications develop.
