Ear infections are one of the most common reasons dogs visit the veterinarian, especially in Northern Kentucky where irritants run wild. At PetWow, we help multiple pet-parents address their dog’s allergies every month – especially in the Spring and Fall months. While some ear irritation may begin mildly, untreated ear infections can become painful and lead to worsening inflammation, odor, discharge, and chronic discomfort. Understanding the signs of ear infections and knowing when to call your veterinarian can help keep your dog comfortable and prevent complications.

Quick Answer:
Dogs with ear infections may show symptoms such as head shaking, scratching at the ears, redness, odor, discharge, pain, or sensitivity around the ears. Ear infections may be caused by allergies, moisture, bacteria, yeast, or other underlying conditions. Veterinary evaluation is often recommended because untreated ear infections can worsen over time, and perscription medication can often clear up the issue quickly.
Common Causes of Ear Infections in Dogs
Allergies are one of the most common underlying causes of recurring ear infections in dogs. Environmental allergies and food sensitivities can both contribute to chronic inflammation inside the ears.
Dogs who swim frequently or have moisture trapped in the ear canal may be more prone to developing ear infections.
Yeast naturally exists on the skin and inside the ears, but overgrowth can occur when the ear environment becomes inflamed or imbalanced.
Bacteria may contribute to painful ear infections, particularly when inflammation or allergies are already present.
Dogs with floppy ears, narrow ear canals, or excessive hair inside the ears may be at increased risk for ear infections due to reduced airflow and trapped moisture.
Parasites can irritate the ear canal and contribute to inflammation, itching, and infection—particularly in younger pets.
Common Signs of Ear Infections in Dogs
Dogs with ear infections may experience:
• Frequent head shaking
• Scratching at the ears
• Redness or swelling
• Odor coming from the ears
• Ear discharge
• Sensitivity when touched around the ears
• Crusting or debris inside the ear
• Tilting the head
• Whining or discomfort
Symptoms may affect one ear or both ears.
When Is an Ear Infection Serious?
Veterinary evaluation is recommended if your dog:
• Has ongoing ear irritation
• Seems painful or uncomfortable
• Develops discharge or odor
• Has recurring ear infections
• Cries when the ears are touched

How Veterinarians Diagnose Ear Infections
Because multiple conditions can contribute to ear problems, veterinarians may perform an ear examination and additional testing to determine the underlying cause.
Evaluation may include:
• Physical examination
• Otoscopic ear exam
• Ear cytology
• Evaluation for allergies or parasites
• Additional diagnostics in chronic cases
Treatment Depends on the Underlying Cause
Treatment recommendations vary depending on the severity and cause of the infection.
Possible treatments may include:
• Ear cleaning
• Prescription ear medications
• Oral medications
• Allergy management
• Parasite treatment
• Ongoing monitoring for chronic cases
Proper diagnosis is important because different infections may require different treatment approaches.
How to Help Reduce the Risk of Ear Infections
While not all ear infections can be prevented, the following may help reduce the risk:
• ✅Keeping ears clean and dry
• ✅Managing underlying allergies
• ✅Using consistent parasite prevention
• ✅Scheduling regular wellness exams
• ✅Monitoring for early signs of irritation
