What Causes Ear Infections in Dogs?
Ear infections in dogs, also known as otitis, typically result from a buildup of bacteria, yeast, or ear mites. The structure of a dog’s ear canal makes them more prone to trapping moisture, debris, and allergens. Common causes include:
- Excess moisture (from swimming or bathing)
- Food or environmental allergies
- Ear mites (common in puppies or outdoor dogs)
- Foreign objects or wax buildup
- Hormonal imbalances or autoimmune diseases
Note: Dogs with floppy ears (like Cocker Spaniels or Basset Hounds) are particularly prone due to limited airflow.
For a trusted veterinary perspective, check out the AKC guide on ear infections in dogs, which outlines symptoms, diagnosis, and treatment options from certified professionals.
Early Warning Signs of Canine Ear Infections
Recognizing early signs of ear infections in dogs can prevent pain and expensive vet visits. Look for:
- Head shaking or tilting
- Scratching at the ear or side of the face
- Redness or swelling in or around the ear
- Unusual odor coming from the ear canal
- Excess ear wax or discharge (yellow, brown, or bloody)
Pro Tip: Gently lifting the ear flap and checking weekly can help you detect changes early.
Advanced or Chronic Symptoms
If an ear infection goes untreated, symptoms can worsen and may include:
- Loss of balance or coordination
- Hearing loss or unresponsiveness to sound
- Thickened skin or crusting around the ear
- Behavioral changes such as irritability or withdrawal
In severe cases, infections may travel deeper into the inner ear, affecting neurological functions.
Types of Ear Infections in Dogs
- Otitis externa: Involves the outer ear canal (most common)
- Otitis media: Affects the middle ear, usually from untreated outer infections
- Otitis interna: Inner ear infection, can impact hearing and balance
Which Dogs Are More at Risk?
Some dogs are genetically or behaviorally predisposed to ear infections. Risk factors include:
- Breeds with floppy or hairy ears (e.g., Golden Retrievers, Poodles)
- Dogs who swim frequently
- Allergy-prone dogs (both food and environmental)
- Dogs with hypothyroidism or autoimmune issues

Diagnosis and Treatment Options
Veterinarians diagnose ear infections through physical exams, swab tests, and sometimes cytology. Treatment depends on the cause but may include:
- Topical ear drops (antibiotic, antifungal, or anti-inflammatory)
- Oral medications for systemic infections
- Ear cleaning with vet-approved solutions
- Addressing underlying conditions like allergies
Never use cotton swabs or alcohol-based products without veterinary guidance.
How to Prevent Ear Infections in Dogs
- Clean ears weekly with a vet-recommended cleaner
- Thoroughly dry ears after swimming or bathing
- Monitor for allergy symptoms and manage them proactively
- Trim hair around the ears (especially in long-haired breeds)
- Feed a high-quality, balanced diet to support immunity

FAQ: Signs of Ear Infections in Dogs
Can a dog ear infection heal on its own?
No. Most infections require treatment to avoid complications or spreading deeper into the ear.
How can I tell if it’s an infection or just wax buildup?
Wax buildup may be mild and odorless. Infections usually involve redness, odor, and behavioral signs like scratching or head shaking.
Can I use human ear drops on my dog?
No. Many human medications are toxic to dogs. Always consult your vet before applying any treatment.
Final Word: Being alert to the signs of ear infections in dogs allows you to act fast and protect your pet from discomfort. Regular checks, gentle cleaning, and prompt veterinary care go a long way in preventing painful complications.
