It is one of the most common reasons why small animals (especially dogs) land up at the veterinarian. It is a very bad condition which, if left untreated, can seriously compromise the animal's quality of life.
Otitis externa is the medical term for inflammation of the external ear canal. The common signs are head shaking, scratching the base of the ear, pain (reluctance to be touched on the ears or head), swelling, redness, unpleasant smells, and sticky ear wax in the ear canal. Since as a pet parent it may sometimes be hard to identify, also symptoms can vary given severity, we suggest any slight discomfort you feel your pet is having, it is better to get it checked by your vet at the earliest.
Diagnosis may be made basis history and observation by veterinarian in case of simple cases, but may require further tests such as otoscopic examination, cytology and culture.
Otitis externa is a very common condition, but its cause is very complicated.
Otitis externa is a complex disease caused by a combination of factors, including
Why is it advised to immediately contact the vet in case you identify some symptoms? To avoid further complications:
When otitis recurs, the balance of the flora in the ear canal is disrupted, so bacteria and yeasts that live there multiply abnormally, causing an infection of various severity. In the event of recurrence, the lining of the canal tends to thicken (sometimes to the point of almost complete obstruction), causing poorer ventilation, favouring the abnormal multiplication of organisms, creating a vicious circle.
The later the condition is treated or the more chronic it becomes, the greater the risk of complications such as otitis media and sometimes surgery is required to treat.
Depends on the situation of the ear. Some pets need almost no care, while some need more frequent care for example if your pet has one or more of the ‘Primary causes, Predisposing factors, or Perpetuating factors’ discussed above. General rule is that the ear canals should be kept dry and always ventilated (for example, one must prevent water from entering the ear canals during bathing). You can ask the vet for details about proper cleaning technique and frequency particularly for your pet.
There isn’t a defined fixed period perse and depends, case to case but essentially treatment must continue until the infection is resolved. For most acute cases, this takes 2-4 weeks. Chronic cases it may take longer, like a few months to resolve and in some cases, a maintenance treatment must continue indefinitely. Your vet will be able to guide you the best in this case depending on severity and nature of the case.
