Dog ear infections are the number one reason owners visit the vet — accounting for 20 percent of all veterinary visits. A single ear infection costs 80-200 dollars for the vet exam, ear cytology, and medication. But most ear infections are preventable with a weekly 2-minute ear cleaning that costs 3-5 dollars per month in supplies. And the infections that do occur can often be treated at home for under 10 dollars if you catch them early. This guide covers the 4 types of ear infections, how to clean your dog’s ears properly, home treatment for mild infections, and when a vet visit is necessary.

Why Dogs Get Ear Infections

The dog ear canal is shaped like an L — it goes down, then turns inward. This shape traps moisture, wax, and debris, creating a warm, dark, humid environment where bacteria and yeast thrive. Dogs with floppy ears (Cocker Spaniels, Golden Retrievers, Beagles, Basset Hounds) are especially prone to infections because the ear flap covers the canal, blocking airflow.

Risk factors:

• Floppy ears — Reduced airflow, trapped moisture
• Swimming — Water stays in the L-shaped canal



• Allergies — Food and environmental allergies cause inflammation in the ear canal, creating conditions for infection
• Excessive hair in the ear canal — Poodles, Schnauzers, and some terriers have hair growing inside the canal that traps wax and moisture
• Hypothyroidism — Underactive thyroid changes skin and ear canal environment
• Humid climate — High humidity promotes yeast growth
• Excessive cleaning — Over-cleaning strips protective wax and causes irritation, making infections more likely

The 4 Types of Ear Infections

1. Yeast Infection (Malassezia) — Most Common

Fungal overgrowth in the ear canal. Causes a distinctive musty or “Frito” smell, brown waxy discharge, head shaking, and scratching. Not usually painful but very itchy.

Common in: Dogs with floppy ears, dogs that swim, dogs with allergies, humid climates.

Home treatment: Clean with a dog ear cleaner containing boric acid or acetic acid (Epi-Otic, 8-12 dollars). After cleaning, apply a natural anti-yeast rinse: 1 part white vinegar to 1 part water (free). Use 2-3 times per week. If not improved in 5-7 days, see a vet for prescription antifungal drops (15-30 dollars).

2. Bacterial Infection

Bacterial overgrowth, often following a yeast infection or allergic inflammation. Causes yellow or green discharge, strong odor, redness, swelling, and pain. The ear may be warm to the touch.

Home treatment: Clean with ear cleaner, but bacterial infections usually need prescription antibiotic drops from a vet. Do not try to treat with home remedies for more than 3-4 days — bacterial infections can damage the eardrum and inner ear if untreated.

Vet treatment: Ear cytology (examining discharge under the microscope, 15-30 dollars) identifies the bacteria. Antibiotic drops (15-40 dollars) for 7-14 days. Severe infections may need oral antibiotics (20-40 dollars) and steroid drops for inflammation (15-25 dollars).

3. Ear Mites (Otodectes cynotis)

Microscopic parasites in the ear canal. More common in puppies and dogs from shelters or multi-dog households. Causes intense itching, head shaking, and a dark, crumbly discharge that looks like coffee grounds.

Treatment: Over-the-counter ear mite drops (8-15 dollars) contain pyrethrin or selamectin. Clean the ear first, then apply drops daily for 7-10 days. Treat all pets in the household (mites spread between animals). Wash bedding in hot water.

Prescription alternative: Revolution or Advantage Multi (topical monthly preventive, 15-25 dollars/month) kills ear mites and prevents recurrence.

4. Allergic Otitis (Allergy-Related Ear Inflammation)

Not an infection but inflammation caused by allergies (food or environmental). The ear canal becomes red, swollen, and produces excess wax. Often recurrent — the infection “comes back” every few weeks because the underlying allergy is not addressed.

Treatment: Address the allergy (see the allergy guide for the 8-week elimination diet). Ear cleaning helps manage symptoms but does not solve the underlying cause. For immediate relief, clean with ear cleaner and apply a hydrocortisone ear cream (over-the-counter, 5-10 dollars) to reduce inflammation. For chronic cases, see a vet for prescription steroid drops (15-25 dollars) and discuss allergy management.

The Weekly Ear Cleaning Routine (2 Minutes, 3-5 Dollars Per Month)

Supplies Needed

• Dog ear cleaner — 8-12 dollars per bottle (lasts 3-6 months). Look for cleaners containing boric acid, acetic acid, or salicylic acid (Epi-Otic, Virbac Epi-Otic Advanced, TrizEDTA). Avoid cleaners with alcohol — they sting and damage inflamed tissue.
• Cotton balls — 2 dollars
• Tissues or soft cloth — For wiping the outer ear

Monthly cost: 2-4 dollars (cleaner amortized over 3-6 months plus cotton balls).

How to Clean Your Dog’s Ears (Step by Step)

1. Have your dog sit or stand — Hold the ear flap up with one hand.
2. Squeeze ear cleaner into the ear canal — Fill the canal until the cleaner is visible at the opening. Do not let the tip of the bottle touch the ear (it contaminates the bottle).
3. Massage the base of the ear — Gently massage the area where the ear meets the head for 20-30 seconds. You will hear a “squishing” sound — this means the cleaner is flowing down the L-shaped canal and breaking up wax.
4. Let your dog shake — Step back and let your dog shake their head. This brings debris and wax up and out of the canal.
5. Wipe the outer ear — Use a cotton ball to wipe the visible part of the ear canal. Do not push cotton into the canal — only clean what you can see.
6. Repeat on the other ear
7. Reward your dog — Give a treat after each ear. This builds positive association and makes future cleanings easier.

Frequency: Once per week for most dogs. Twice per week for dogs that swim, have floppy ears, or are prone to infections. Do not clean more than twice per week — over-cleaning strips protective wax and causes irritation.

What NOT to Do

• Do not use cotton swabs (Q-tips) — They push wax deeper into the canal and can damage the eardrum.
• Do not use hydrogen peroxide — It damages healthy tissue in the ear canal.
• Do not use alcohol — It stings and dries out the ear canal, causing more problems.
• Do not flush the ear if the eardrum may be ruptured — If there is severe pain, foul odor, or your dog cries when you touch the ear, see a vet before cleaning. Flushing a ruptured eardrum pushes debris into the middle ear, causing permanent damage.
• Do not pluck ear hair unless directed by a vet — Plucking causes inflammation and micro-wounds that can become infected. Some groomers pluck routinely, but vets generally advise against it unless the hair is causing recurrent infections.

Home Treatment for Mild Ear Infections (Under 10 Dollars)

The Vinegar Rinse (For Yeast Infections)

Mix 1 part white vinegar with 1 part water. After cleaning with ear cleaner, flush 2-3 drops of the vinegar solution into the ear, massage, let your dog shake, and wipe. The acidic environment kills yeast and prevents regrowth. Use 2-3 times per week. Cost: 1 dollar for a bottle of white vinegar.

Do not use the vinegar rinse if the ear is red, swollen, or painful — the acid stings on broken skin. Only use on mild yeast infections with brown waxy discharge and no signs of pain.

The Green Tea Rinse (Soothing and Anti-Inflammatory)

Brew a cup of green tea, let it cool to room temperature, and use 2-3 drops in the ear after cleaning. Green tea contains antioxidants and has mild anti-inflammatory properties. Safe for all ear types. Cost: 1-2 dollars for tea bags.

Over-the-Counter Ear Drops

Several OTC ear drops are available at pet stores and online:

• Zymox Ear Solution (without hydrocortisone) — 12-18 dollars. Contains enzymes that break down bacterial and yeast cell walls. Effective for mild to moderate infections. Use once daily for 7 days.
• Zymox Ear Solution with Hydrocortisone — 15-20 dollars. Same as above but adds hydrocortisone for inflammation and itching. Better for allergic ears.
• Vet’s Best Ear Relief — 8-12 dollars. Natural ingredients (tea tree oil, chamomile, clove oil). Mildly effective for yeast and soothing for inflammation.

When to See the Vet

See a vet if:

• The ear is painful — your dog cries or pulls away when you touch it
• There is yellow or green discharge (bacterial infection needs prescription antibiotics)
• The ear is swollen, red, or hot to the touch
• Your dog holds the head tilted to one side (signs of inner ear involvement)
• There is a foul smell that does not improve with cleaning
• Home treatment has not improved the infection in 5-7 days
• Infections recur more than 3 times per year (underlying cause needs investigation)
• Your dog has a fever, is lethargic, or is not eating
• There is discharge from the eye on the same side as the affected ear (signs of middle ear infection)

Vet Costs for Ear Infections

Preventing Recurrent Ear Infections (Free)

• Dry ears after swimming or bathing — Use a cotton ball to gently absorb water from the outer canal. Do not push into the canal.
• Clean weekly — Once per week with a quality ear cleaner prevents wax and debris buildup.
• Address allergies — If your dog has recurrent ear infections, allergies are the likely cause. See the 8-week elimination diet guide.
• Keep ears dry — Avoid getting water in the ears during baths. Place a cotton ball in the outer ear during bathing, remove after.
• Trim ear hair (with vet approval) — For breeds with excessive ear canal hair, trimming (not plucking) improves airflow.
• Feed a high-quality diet — Poor nutrition affects skin and ear health. Omega-3 fatty acids (fish oil, 3-5 dollars/month) reduce inflammation.
• Check ears weekly during grooming — Look for redness, discharge, or odor before it becomes a full infection.

The Bottom Line

Dog ear infections cost 80-200 dollars per vet visit but are preventable with a 2-minute weekly ear cleaning using a 8-12 dollar bottle of ear cleaner (lasts 3-6 months) and cotton balls (2 dollars). Fill the ear canal with cleaner, massage the base for 30 seconds, let your dog shake, and wipe the outer ear. Do this once per week — twice for floppy-eared dogs and swimmers. Never use Q-tips, hydrogen peroxide, or alcohol. For mild yeast infections, use a 1:1 vinegar and water rinse (1 dollar) or Zymox ear drops (12-18 dollars) for 7 days. See a vet for: pain, yellow or green discharge, swelling, head tilt, foul odor, or infections that do not improve in 5-7 days. If your dog gets ear infections more than 3 times per year, the underlying cause is likely allergies — address the allergy, not just the ear. Dry ears after swimming, feed omega-3 fish oil (3-5 dollars/month) for skin and ear health, and check ears weekly during grooming. The 2-4 dollars per month you spend on ear cleaner prevents 80-200 dollar vet bills and keeps your dog comfortable and itch-free.
