Ear Infections in Dogs and Cats in Copake Falls, NY
Ear infections are one of the most common reasons dogs visit the veterinarian — and one of the most frequently undertreated. Without identifying the underlying cause, infections recur. At Copake Veterinary Hospital, we don’t just treat the immediate infection; we work to understand why it happened and how to prevent it from coming back.

Otitis externa — infection of the outer ear canal — occurs when the normal environment of the ear canal is disrupted, allowing yeast or bacteria to overgrow. The ear canal in dogs is shaped like an “L,” creating a warm, moist environment that is prone to infection when the balance is off.
In dogs, the most common causes are allergies (environmental or food-related), moisture (swimming, bathing), ear anatomy (floppy ears, excessive hair in the canal), foreign bodies, and ear mites. In cats, ear mites are the most common cause of outer ear infection, though bacterial and yeast infections occur as well.
Ear infections can involve the outer ear canal (otitis externa), the middle ear (otitis media), or — in severe cases — the inner ear (otitis interna). Middle and inner ear infections are more serious and require more aggressive treatment.
Signs of an Ear Infection
- Head shaking or ear scratching
- Redness, swelling, or warmth inside the ear
- Odor — yeasty, musty, or foul-smelling discharge
- Dark brown, yellow, or black discharge
- Pain when the ear is touched
- Tilting the head to one side
- Loss of balance or walking in circles (indicates inner ear involvement — seek prompt care)
- Reduced hearing
Diagnosis and Treatment at Copake Veterinary Hospital
Accurate diagnosis is the foundation of effective treatment. When we evaluate an ear infection, we:
- Perform a thorough otoscopic examination of the ear canal and eardrum
- Collect a sample of discharge for cytology — microscopic examination to identify whether the infection is yeast, bacteria, or mixed, and what organisms are present
- Culture the ear when appropriate, particularly for chronic or recurrent infections where antibiotic resistance may be a factor
- Evaluate for foreign bodies, masses, or anatomic factors contributing to the infection
Treatment depends on the type and severity of infection and typically includes professional cleaning of the ear canal and an appropriate topical or systemic medication. We will also discuss maintenance ear care and steps to reduce recurrence.
The Allergy Connection
Recurrent ear infections — particularly in dogs who have them repeatedly, year after year — are frequently a symptom of underlying allergies. Environmental allergies (atopy) and food allergies both cause chronic inflammation in the skin and ears that sets the stage for infection. Treating the ear infection without addressing the allergy means the infection will almost certainly return.
If your dog has had multiple ear infections, our allergy testing services and dermatology program can help identify and manage the underlying cause. Our in-house laboratory allows same-day cytology so we know what we’re treating before prescribing. And for pets with recurrent infections affecting overall comfort, our pain management team can help address the discomfort while the underlying condition is addressed.

Frequently Asked Questions About Ear Infections in Dogs and Cats
Can I treat my dog’s ear infection at home without seeing a vet?
Over-the-counter ear cleaners can help with mild wax buildup and maintenance, but they do not treat infection. Using the wrong product on an infected ear — or using anything when the eardrum is ruptured — can worsen the problem significantly. Ear infections require diagnosis by cytology to identify the causative organism and prescribe the right medication.
Why does my dog keep getting ear infections?
Recurrent ear infections are almost always a sign of an underlying condition — most commonly allergies (environmental or food), but also ear anatomy, hormonal conditions like hypothyroidism, or immune system dysfunction. Treating each infection without addressing the root cause will result in continued recurrence. If your dog has had more than two ear infections in a year, an underlying cause should be investigated.
Are ear infections painful for dogs?
Yes — often significantly so. The ear canal is densely innervated, and infected, inflamed tissue is painful. Many dogs with ear infections are reluctant to have their heads touched, shake their heads constantly, and are clearly uncomfortable. Prompt treatment relieves this pain and prevents the infection from progressing deeper into the ear canal.
What’s the difference between a yeast infection and a bacterial infection in the ear?
They look and smell different, respond to different medications, and are identified by cytology (microscopic examination of ear discharge). Yeast infections typically produce dark brown, waxy discharge with a characteristic musty odor. Bacterial infections may produce yellow or cream-colored purulent discharge. Many infections are mixed (both yeast and bacteria), which affects treatment selection. This is why cytology before treatment matters.
My cat is shaking his head and scratching his ear — could it be ear mites?
Ear mites are the most common cause of ear disease in cats, particularly young cats or cats with outdoor exposure. They cause intense itching and produce dark, crumbly, coffee-ground-like discharge. Ear mites are contagious to other cats and dogs in the household. Diagnosis is made by otoscopic examination or cytology, and treatment is typically straightforward with the right product.
How do I clean my dog’s ears at home to help prevent infections?
Regular ear cleaning with a veterinarian-recommended cleanser removes excess moisture and wax that create a favorable environment for infection. We’ll show you the proper technique at your appointment. Dogs who swim frequently, have floppy ears, or have a history of ear infections often benefit from routine cleaning after water exposure.
