By:  Dr. Katherine Backel | DVM, DACVD

Dog ear infections are a common concern for many pet owners. Being aware of the symptoms, treatment options, and preventive measures can significantly contribute to maintaining your furry friend’s health and happiness. Ear infections in dogs can cause considerable discomfort and, if not treated, can result in more serious health problems. We aim to provide a detailed overview of dog ear infections, equipping you with the knowledge to recognize, treat, and prevent these infections effectively.

Symptoms

Recognizing the signs of an ear infection early can make a significant difference in your dog’s comfort and recovery time. Here are some common symptoms to watch for:

  • Frequent scratching or pawing at the ear: Dogs with ear infections often scratch their ears due to itching and discomfort.
  • Head shaking or tilting: If your dog is persistently shaking their head or tilting it to one side, it could indicate an ear issue.
  • Redness and swelling: Infected ears often appear red and swollen. *Be sure to check under the ear flap.
  • Unusual odor: A strong, unpleasant smell from the ear is usually a sign of infection.
  • Discharge: You may notice a white, yellow, brown, or bloody discharge from the ear.
  • Behavioral changes: Dogs in pain may become irritable, lethargic, or less interested in playing and eating.
  • Balance problems: Severe infections can affect your dog’s balance, causing them to tilt their head to one side, stumble or seem disoriented. Some dogs may be less willing to jump or walk up/down stairs.

Treatment

Treating ear infections promptly is crucial to prevent complications. Here are some home care tips and veterinary treatments to consider:

Home Care Tips

  • Cleaning the ears: Use a vet-recommended ear cleaner to gently flush your dog’s ears. Excess cleaner can be wiped away with a cotton ball. Avoid using cotton swabs as they can push debris further into the ear canal.
  • Monitoring and prevention: Keep an eye on your dog’s ears and clean them regularly, especially after swimming or bathing.
  • Avoiding irritants: Keep your dog away from potential allergens and irritants that could trigger an infection.

Veterinary Treatments

If home care does not improve the condition, it’s essential to seek veterinary assistance. Treatments your vet might recommend include:

  • Thorough examination: Your vet will inspect the ear canal using an otoscope to assess the extent of the infection. Your vet will also take a swab sample from your dog’s ear to determine the type and severity of infection.
  • Ear cleaning: A professional cleaning may be necessary to remove debris and discharge.
  • Medications: Typically topical antibiotics, antifungals, and/or anti-inflammatory medications are prescribed, depending on the cause.
  • Follow-up care: Length of treatment will depend on the severity and chronicity of infection. Regular check-ups may be required to ensure the infection is fully resolved and to prevent recurrence.

Medicine

Understanding the medications used to treat ear infections can help you better care for your pet.

Over-the-Counter Options

  • Ear cleaners: Available at pet stores, these can help maintain ear hygiene and prevent infections.
  • Medicated ear drops: Some OTC ear drops can provide relief for mild infections, but it’s crucial to consult your vet before using them.

Prescription Medications

  • Antibiotics: If the infection is bacterial, your vet may prescribe antibiotic ear drops or oral antibiotics.
  • Antifungals: Fungal infections require specific antifungal treatments.
  • Anti-inflammatories: These can help reduce swelling and pain, improving your dog’s comfort.
  • Pain relievers: In some cases, pain relief medication may be necessary to help your dog cope with discomfort.

Contagiousness

One common concern among pet owners is whether dog ear infections can spread to other pets or humans. Typically, ear infections in dogs are not contagious. They are usually caused by factors such as allergies, moisture, foreign bodies, or ear mites. However, if the underlying cause is an infectious agent like mites, it could potentially spread to other pets. Always practice good hygiene and consult your vet if you have multiple pets showing similar symptoms.

Prevention

Preventing ear infections is often easier than treating them. Here are some tips to help keep your dog’s ears healthy:

  • Regular ear cleaning: Clean your dog’s ears weekly with a vet-approved cleaner, especially if they are prone to infections.
  • Drying ears thoroughly: After swimming or bathing, make sure to dry your dog’s ears to prevent moisture buildup.
  • Monitoring for allergies: If your dog has allergies, work with your veterinarian to manage them. In many dogs, recurrent ear infections may be the only sign of allergies.
  • Routine check-ups: Regular veterinary visits can help catch and address potential ear problems early.
  • Proper grooming: Keeping the hair around your dog’s ears trimmed can improve air circulation and reduce the risk of infection. Avoid plucking ear hair unless deemed necessary by your veterinarian.

Conclusion

Dog ear infections are a common but manageable issue. By recognizing the symptoms, seeking appropriate treatment, and taking preventive measures, you can help ensure your dog stays comfortable and healthy. If you suspect your dog has an ear infection, don’t hesitate to consult your veterinarian for professional advice and treatment. Your vet can provide personalized care tailored to your dog’s specific needs, ensuring the best possible outcome.
