Very common. Most pets will experience at least one ear infection in their lifetime. Dogs with floppy ears, like Cocker Spaniels, Basset Hounds, and Golden Retrievers, are especially prone to recurring infections due to reduced airflow in the ear canal. Puppies often develop infections from ear mites, while cats can be affected by mites, trauma, or allergic reactions

Common signs include:

• Scratching at the ears

• Frequent head shaking

• Whining or signs of discomfort

• Red, swollen ear canals

• Foul odor from the ears

• Dark, waxy, or pus-like discharge

• Sensitivity when ears are touched

If your pet shows any of these symptoms, call Eden Animal Hospital right away for an evaluation.

Ear infections can be triggered by a variety of underlying conditions, including:

• Bacteria or yeast overgrowth

• Ear mites (especially in young pets and cats)

• Allergies (food or environmental)

• Excess moisture, often from bathing or swimming

• Wax buildup or excessive hair in the ear canal

• Foreign bodies like grass seeds or debris

• Endocrine disorders, like hypothyroidism

• Over-cleaning or trauma from scratching

At Eden Animal Hospital, we use an otoscope to examine the inner ear and assess inflammation, wax buildup, or signs of mites. We may also perform cytology—collecting a sample of ear debris to check under the microscope for bacteria, yeast, or parasites. For chronic or severe cases, a digital otoscope allows a magnified view for deeper analysis.

Treatment depends on the cause but may include:

• Prescription ear drops (antibiotic, antifungal, or anti-inflammatory)

• Oral medications for severe infections

• Professional ear cleaning to remove debris and improve medication absorption

• Allergy treatment if the infection is allergy-related

• Hair removal in the ear canal if it’s contributing to blockage

​

Dr. Kerolos will also guide you on proper cleaning techniques and preventive care for future flare-ups.

Only use products specifically formulated for pets. Never use hydrogen peroxide, alcohol, or household cleaners, which can irritate the ear canal and worsen the problem. We can recommend safe, vet-approved solutions during your visit.
