Otitis Externa

Otitis Externa

The most common ear disease in pets is otitis externa. This is an inflammation of the external ear canal, the part of the ear between the eardrum and the outer surface of the ear. The disease has a number of possible causes and can become a chronic problem in susceptible animals. 

How Otitis Externa Affects Your Pet

Due to some type of irritation in the outer ear, the glands in the area begin to overproduce wax. This leads to greater irritation and creates an environment that attracts bacteria and fungus. Over time, the skin in the area thickens in response to inflammation, and the ear canal narrows. This worsens the inflammation and makes the pet more likely to develop bacterial and fungal infections of the ear. Otitis externa is a complex pet disease, and veterinarians must consider four types of factors when diagnosing and treating the condition. These are primary, secondary, predisposing and perpetuating factors.  Primary factors, including the following, directly cause this pet health problem: Parasites, Foreign bodies, Tumors, Autoimmune diseases, Endocrine diseases, Irritants and Allergies. Secondary factors, such as bacterial and fungal infections, complicate the disease. Predisposing factors, including the following, make pets more likely to develop otitis externa: Floppy ears, Narrow ear canals, Excessive wax secretion, Excessive hair in the ears, Immune system suppression, Systemic disease, Excessive moisture in the ear canal and Skin damage in the ear canal. Perpetuating factors, such as middle ear infection and damage to the ear canal, tend to make the disease harder to cure.

Common Symptoms of Otitis Externa

Symptoms of otitis externa include the following: Head shaking, Scratching or pawing at the ears, Discharge from one or both ears, Redness of one or both ears, Swelling of the ear canal, Scaling of the skin of the ear canal, Pain and A bad odor emanating from one or both ears.

Treatments for Otitis Externa

If the condition is caused by a tumor or a foreign body, the offending structure must be removed and the inflammation treated with topical medications. In most other cases, topical medications and ear cleaning are sufficient to alleviate the symptoms of otitis externa. However, any pet that experiences more than two ear infections in a six month period should have a full work up to look for underlying health issues.

Breeds Affected

All cats and dogs are susceptible to otitis externa, but members of some breeds are predisposed to the condition. Canine breeds prone to developing otitis externa include the following: Shar Pei, Standard Poodle, Miniature Poodle, Cocker Spaniel, German Shepherd, Old English Sheepdog, Labrador Retriever, Shih Tzu, Bloodhound and Basset Hound. Feline breeds predisposed to the condition include the following: Persian, Himalayan, Birman and Siamese.

Pet Insurance

When adding a dog or cat to your family you want to make sure your pet is happy, healthy and protected. During its lifetime your pet is exposed to many illnesses and diseases and some breeds are affected by a congenital disease which is a condition existing at birth. At these moments when your pet is ill or maybe needs surgery, you want to be protected for the unexpected and high veterinarian costs.
