Dog Ear Infections: Symptoms, Causes, and Prevention Guide
Dog ear infections are a common concern for many dog owners. Recognizable symptoms include whining, scratching, and head shaking. These infections are especially prevalent in dogs with floppy ears, like Basset Hounds and Cocker Spaniels. An estimated 20% of dogs suffer from ear disease, which can affect one or both ears. Fortunately, there are measures you can take to reduce the severity and frequency of these infections, including using dog ear care products for prevention.
Types of Dog Ear Infections
There are three types of ear infections in dogs: otitis externa, otitis media, and otitis interna. Otitis externa is the most common, affecting the outer ear canal’s lining. Otitis media and interna affect the middle and inner ear canal, respectively, often due to the spread of an external ear infection. These more severe infections can lead to deafness, facial paralysis, and vestibular signs, making early treatment and prevention crucial.
Symptoms of Dog Ear Infections
While some dogs show no symptoms other than wax and discharge buildup, ear infections typically cause significant discomfort, with signs including:
- Head shaking
- Scratching at the affected ear
- Dark discharge
- Odor
- Redness and swelling of the ear canal
- Pain
- Itchiness
- Crusting or scabs in the ears
Causes of Ear Infections in Dogs
Dogs are more prone to ear infections due to their vertical ear canal, which forms an L-shape that retains fluid. Common causes include bacteria, yeast, and in puppies, ear mites. Factors increasing susceptibility include:
- Moisture, fostering bacterial and yeast growth
- Allergies, leading to ear disease in a significant number of dogs with allergic skin disease or food sensitivities
- Endocrine disorders, such as thyroid disease
- Autoimmune disorders
- Wax buildup
- Foreign bodies
- Ear canal injury
- Excessive cleaning
Diagnosis and Treatment of Dog Ear Infections
If your dog shows symptoms of an ear infection, consult your veterinarian promptly. Quick treatment is essential to prevent the infection from spreading to the middle and inner ear. During your visit, provide a detailed history, including the duration of symptoms, any allergies, medications, diet, ear cleaning routine, and past ear infections.
The veterinarian will conduct a physical examination, possibly sedating your dog for a thorough evaluation. The exam may include visual assessments, otoscope examinations, gentle palpation, microscopic sample examinations, cultures, biopsies, or X-rays.
Treatment involves thoroughly cleaning your dog’s ears with a medicated cleanser and possibly prescribing ear drops, oral antibiotics, and anti-inflammatory medications. Most infections resolve within 1-2 weeks with proper treatment, but severe or chronic cases may take longer. In extreme cases, surgery like a Total Ear Canal Ablation (TECA) might be necessary to prevent recurrence.
Follow your veterinarian’s instructions carefully and complete the full course of medication to avoid complications like resistant infections.
Preventing Dog Ear Infections
Prevention is key. To prevent moisture-related infections, thoroughly dry your dog’s ears after swimming and bathing. Consult your vet about using dog ear powder to keep ears dry. For dogs prone to recurrent infections, managing underlying causes like allergies is crucial.
Regular ear cleaning can also help prevent infections. BestPetPlanet recommends filling the ear canal with a dog ear cleaning solution, massaging the outside of the vertical ear canal, and wiping it out with absorbent gauze. Avoid paper towels or cotton, as they can leave fibers that cause irritation. Use cotton swabs for the external ear flaps only, and consider dog ear cleaning wipes for removing external dirt and debris.
Ear infections are a recurrent issue for many dogs, but with proper care and your veterinarian’s guidance, you can keep your dog’s ears healthy and comfortable. Always seek veterinary advice at the first sign of an ear infection to prevent serious complications.
