Dog Ear Infection Treatment Options & Prevention

Dog ear infections are a common and frustrating issue for many pet parents. If your dog is constantly scratching their ears, shaking their head, or if you notice a strong odor coming from their ears, they may have an infection. Ear infections can be painful and, if left untreated, may lead to more serious health problems.

Understanding the causes, symptoms, and best treatment options can help you take quick action to relieve your dog’s discomfort. In this guide, we’ll cover how to treat a dog ear infection and how to prevent future infections—including how a fresh, balanced diet like Ollie Fresh Dog Food can support ear health.

What Are Ear Infections in Dogs?

A dog ear infection (also called otitis) is an inflammation of the ear canal caused by bacteria, yeast, or parasites. Infections can occur in three different parts of the ear:

• Otitis externa – Infection of the outer ear canal (most common).
• Otitis media – Infection of the middle ear, often caused by untreated outer ear infections.
• Otitis interna – Infection of the inner ear, which can affect balance and hearing.

Most dogs will experience an outer ear infection at some point in their lives. However, if left untreated, the infection can spread deeper into the ear, leading to more serious complications such as hearing loss or balance issues.

Symptoms of a Dog Ear Infection

If your dog has an ear infection, you may notice:

• Frequent head shaking or ear scratching
• Redness, swelling, or discharge in the ear
• A strong, unpleasant odor from the ear
• Whimpering or sensitivity when touched
• Loss of balance (if the infection spreads to the inner ear)

Catching an ear infection early is key to preventing serious pain and complications. If your dog shows any of these symptoms, it’s important to take action right away.

Causes of Dog Ear Infections

A dog ear infection (also known as otitis) happens when bacteria, yeast, or parasites multiply inside the ear canal. Several factors can make your dog more likely to develop an ear infection.

1. Bacteria and Yeast Overgrowth

Dogs naturally have bacteria and yeast in their ears, but when these microorganisms multiply too quickly, they cause an infection. This overgrowth can happen due to moisture buildup, allergies, or a weakened immune system.

2. Allergies (Food or Environmental)

Allergies are one of the most common reasons for chronic ear infections in dogs. Dogs with food allergies or sensitivities often experience itchy ears, leading to inflammation and infection. Environmental allergens like pollen, dust mites, and mold can also trigger infections.

How Ollie Helps: Feeding Ollie Fresh Dog Food eliminates many common allergens found in low-quality kibble, like fillers, artificial additives, and certain grains. A fresh, balanced diet can help reduce inflammation and lower the risk of recurring ear infections.

3. Moisture Buildup (Swimming & Baths)

Dogs who swim frequently or get their ears wet during baths are more prone to infections. Moisture creates the perfect environment for bacteria and yeast to thrive, especially in dogs with floppy ears (like Cocker Spaniels or Basset Hounds).

4. Ear Mites (Especially in Puppies)

Ear mites are tiny parasites that live inside the ear canal, causing intense itching and irritation. They are more common in puppies and can lead to secondary bacterial infections if left untreated.

5. Excessive Earwax or Foreign Objects

Some dogs naturally produce more earwax than others, which can trap dirt and debris, leading to infections. Small foreign objects (like grass seeds) can also get stuck inside the ear canal and cause irritation.

How to Treat a Dog Ear Infection

If your dog has an ear infection, quick treatment is key to preventing pain and complications. Treatment will depend on the severity of the infection, but in most cases, a combination of veterinary care, medication, and proper ear cleaning is needed.

1. Veterinary Diagnosis

A veterinarian should examine your dog’s ears to determine the cause of the infection. Vets use an otoscope to look inside the ear and may take a swab to check for bacteria, yeast, or parasites. Identifying the exact cause helps ensure the right treatment.

Your vet may recommend:

• Antibiotics (for bacterial infections).
• Antifungal medications (for yeast infections).
• Anti-inflammatory medications (to reduce pain and swelling).
• Ear drops that contain a combination of medication and soothing ingredients.

When to See a Vet Immediately:

• If your dog is in pain, tilting their head, or has trouble walking.
• If there’s a large amount of discharge or a foul odor.
• If home remedies haven’t improved symptoms after a couple of days.

2. Prescription Medications

Veterinary-prescribed medications are the most effective dog ear infection treatment and work quickly to relieve symptoms. Your vet may prescribe:

• Antibiotic ear drops (if bacteria are the cause).
• Antifungal ear drops or oral medication (for yeast infections).
• Steroids (to reduce severe inflammation and pain).
• Oral antibiotics (for deep or recurring infections).

These treatments typically clear up an infection within 7 to 14 days, but it’s important to follow your vet’s instructions exactly and complete the full course of medication—even if symptoms improve early.

Cleaning the Ears Properly

Keeping your dog’s ears clean is essential for both treating and preventing infections. However, cleaning must be done gently and correctly to avoid making the infection worse.

Step-by-Step Guide to Cleaning Your Dog’s Ears

1. Gather Your Supplies: Use a vet-approved ear cleaner, cotton pads or gauze (not cotton swabs), and treats to keep your dog calm.
2. Hold Your Dog’s Ear Flap Up: This helps expose the ear canal and allows the cleaner to reach deep inside.
3. Apply the Ear Cleaner: Squeeze a small amount into the ear canal, following the product instructions.
4. Massage the Base of the Ear: Gently rub the base of the ear for about 30 seconds to help break up debris.
5. Let Your Dog Shake Their Head: This helps loosen wax and dirt inside the ear.
6. Wipe Away Debris: Use a cotton pad or gauze to wipe the outer ear and remove any loosened debris.
7. Reward Your Dog! Give them a treat to make the process positive.

What NOT to Do:

• Don’t use Q-tips. They can push debris deeper and damage the ear canal.
• Don’t clean too often. Over-cleaning can remove healthy bacteria and irritate the ear.
• Don’t use hydrogen peroxide or alcohol. These can dry out and damage the ear tissue.

How Ollie Can Help

Dogs with food sensitivities are more prone to ear infections, and a fresh, balanced diet can help reduce inflammation. Our Fresh Dog Food is free from artificial fillers and common allergens, making it a great choice for dogs prone to ear infections.

Home Remedies for Mild Dog Ear Infections

If your dog has a mild ear infection or ear irritation, you may be able to manage it at home with gentle cleaning and natural remedies. However, home treatments should never replace veterinary care for severe infections, chronic issues, or infections that aren’t improving.

1. Warm Saline Solution (For Gentle Cleaning)

A warm saline rinse can help flush out mild debris and soothe irritation. To make a simple solution:

• Mix 1 cup of warm water with ½ teaspoon of salt.
• Soak a cotton pad in the solution and gently wipe the outer ear.
• Avoid pouring liquid directly into the ear, as it may trap moisture.

2. Apple Cider Vinegar (Diluted for Yeast Infections)

Apple cider vinegar has natural antibacterial and antifungal properties, making it useful for mild yeast infections. However, do not use this remedy if your dog’s ear is red, swollen, or has open sores, as it can sting.

How to use it:

• Mix equal parts apple cider vinegar and water.
• Dip a cotton pad into the mixture and gently wipe the ear flap.
• Do not pour vinegar directly into the ear canal.

3. Coconut Oil or Aloe Vera (For Soothing Irritation)

Both coconut oil and aloe vera have anti-inflammatory properties that can help relieve itching and minor irritation. To use:

• Warm a small amount of coconut oil until it becomes liquid.
• Apply a tiny amount to a cotton pad and gently wipe the outer ear.
• You can also use pure aloe vera gel in the same way.

When to Avoid Home Remedies

• If the infection is severe, painful, or has a bad smell.
• If your dog’s symptoms aren’t improving within 48 hours.
• If your dog has chronic or recurring ear infections.

How To Prevent Future Ear Infections For Your Dog

Once your dog has had an ear infection, you’ll want to take steps to prevent it from happening again. Regular ear care, proper grooming, and a healthy diet can make a big difference in reducing the risk of infections.

1. Regular Ear Cleaning

Cleaning your dog’s ears once a week or as needed helps remove dirt, wax, and bacteria before they cause an infection.

• Use a vet-approved ear cleaner (avoid homemade solutions unless advised).
• Wipe the outer ear gently with a soft cotton pad (never use Q-tips).
• Avoid over-cleaning, as it can strip away healthy bacteria and cause irritation.

2. Keep Ears Dry After Swimming & Baths

Moisture buildup is one of the biggest triggers for ear infections, especially in dogs with floppy ears.

How to Prevent Moisture Buildup:

• Dry your dog’s ears thoroughly with a soft towel after swimming or bathing.
• Use a dog-safe ear drying solution if your pup swims often.
• Avoid getting shampoo or water inside the ears during baths.

3. Manage Allergies with a Fresh, Balanced Diet

Food allergies are a major cause of chronic ear infections in dogs. Many commercial dog foods contain fillers, artificial additives, and common allergens (like wheat, corn, or soy) that can trigger inflammation.

How Ollie Helps:

• Ollie Fresh Dog Food is made with real, human-grade ingredients and avoids common allergens.
• A high-protein, low-filler diet helps support a strong immune system.
• Ingredients like omega-3s from fish oil help reduce inflammation that can contribute to ear infections.

4. Use Supplements That Support Ear & Skin Health

Adding skin-boosting supplements to your dog’s routine can help prevent recurring ear infections.

Ollie Skin & Coat Chews contain:

• Omega-3 fatty acids – Reduce inflammation and promote healthy skin.
• Biotin & vitamin E – Support skin barrier function and ear health.
• Zinc – Helps maintain a strong immune system.

5. Regular Vet Checkups

Even with proper care, some dogs are prone to ear infections due to genetics or allergies. Regular vet visits help catch early signs of infection before they become serious.

Ask Your Vet About:

• How often to clean your dog’s ears based on breed and ear shape.
• Allergy testing if your dog has frequent ear infections.
• Medications or diet changes to help prevent recurring issues.

When to See a Vet Immediately

While some mild ear infections can be treated at home, certain symptoms indicate that your dog needs veterinary care as soon as possible. Delaying treatment could lead to severe pain, deeper infections, or even hearing loss.

Signs Your Dog Needs a Vet Right Away

• Persistent Symptoms – If your dog’s infection doesn’t improve within 48 hours of home care or worsens.
• Swelling or Extreme Redness – Inflamed, swollen ears may indicate a severe bacterial infection.
• Strong Odor or Thick Discharge – Yellow, green, or bloody discharge with a foul smell means an advanced infection.
• Loss of Balance or Walking in Circles – This could be a sign that the infection has spread to the inner ear and is affecting your dog’s equilibrium.
• Excessive Pain – If your dog whimpers, yelps, or resists touching near their ears, the infection may be severe.

What to Expect at the Vet

• Ear Examination – Your vet will check for redness, swelling, discharge, and deep infections using an otoscope.
• Ear Swab Test – A swab may be taken to identify bacteria, yeast, or mites, ensuring the right treatment.
• Medication Prescription – The vet may prescribe antibiotic drops, antifungal treatments, or steroids for pain and swelling.
• Ear Cleaning or Flushing – For severe infections, your vet may perform a deep ear cleaning to remove debris.

Frequently Asked Questions About Dog Ear Infections

1. What is the fastest way to treat a dog ear infection?

The fastest way to treat a dog ear infection is to visit a veterinarian for a proper diagnosis. Your vet may prescribe antibiotic ear drops, antifungal medication, or anti-inflammatory treatments. If treated early, most infections improve within 7 to 14 days.

2. Can I treat my dog’s ear infection at home?

For mild cases, you can try home remedies like saline solution or diluted apple cider vinegar to clean the ears. However, if the infection is severe, persistent, or causing pain, a vet visit is necessary. Never use hydrogen peroxide or alcohol, as they can irritate the ear.

3. How do I know if my dog has an ear infection or just dirty ears?

Dirty ears may have a little wax or mild odor, but an ear infection typically causes redness, swelling, itching, excessive scratching, and a strong odor. If you notice discharge or your dog is in pain, it’s likely an infection.

4. What happens if a dog ear infection goes untreated?

Untreated dog ear infections can spread to the middle or inner ear, leading to hearing loss, balance issues, and chronic pain. In severe cases, an untreated infection can cause ruptured eardrums or permanent ear damage.

5. Are certain dog breeds more prone to ear infections?

Yes! Dogs with floppy ears (like Cocker Spaniels, Basset Hounds, and Golden Retrievers) are more likely to develop ear infections because their ear canals trap moisture and bacteria. Breeds with allergy-prone skin (like Bulldogs and French Bulldogs) are also at higher risk.

6. Can diet affect dog ear infections?

Yes! Food allergies are a common cause of recurring ear infections in dogs. Many commercial dog foods contain fillers, artificial additives, and grains that trigger inflammation. Feeding a fresh, balanced diet like Fresh Dog Food can help reduce allergy-related ear infections.
