The purpose of this guide is to provide you a wealth of information regarding ear problems in dogs so that you can better understand the complicated nature of ear diseases. This guide was written to help empower you to make informed decisions regarding the necessary treatment choices for your dog's ears. As a dog owner, this guide will help you take a positive step in caring for your dog's health and long-term ear maintenance. Your dog's ear is a complex structure that not only facilitates hearing, but also plays a major role in the control of balance and coordination. Inflammation of the ear is known as otitis. Otitis can be acute or chronic, and affect one or both ears. Canine otitis is a prevalent issue, and is one of the most common reasons for owners to seek veterinary treatment for their dogs.Otitis is usually a multifactorial problem. This means there are several underlying issues which, in combination, cause the disease. In dogs, otitis has been linked to many different underlying causes. It is a disease process which can be challenging to treat and manage successfully. Unfortunately, otitis also has a high rate of recurrence, which can be frustrating for you the owner, and painful for your dog. Chronic otitis requires an accurate workup by a veterinarian to get to the root of the problem, combined with a multi-tiered approach to treatment. Long-term follow-up is usually necessary. When chronic ear infections are inadequately treated, or treated too late, the consequence can be lifelong pain and loss of hearing for your dog. Through a proactive approach to your dog's care and treatment, such consequences can be prevented.
