At-Home Care for Dog Ear Infections
Ear infections are highly common in dogs, ranking as one of the top 10 reasons they’re seen by veterinarians. Not only are ear infections uncomfortable and painful; left untreated, they can result in permanent damage.
Here, we’ll outline some ways to provide safe at-home care for dog ear infections (as well as remedies to avoid), help you recognize when it’s time to call the veterinarian, and offer tips on preventing ear infections.
Any DIY care provided at home should be viewed as strictly complementary, not as a replacement for professional care. Please consult with a veterinarian if your dog is exhibiting any signs of an ear infection, and whether the tips described here are appropriate for your dog.
What Causes Ear Infections in Dogs?
Yeast and bacteria already inhabit the dog’s ear in small numbers without causing any issues. Dog ear infections typically occur when the ear canal's environment is disrupted, creating a hospitable environment for the microorganisms to thrive.
Here are some things that cause these microorganisms to overpopulate the ear and eventually become an ear infection:
Possible Dog Ear Infection Causes
- Allergies. Allergies are the most frequent underlying cause of ear infections. As many as 90% of recurrent ear infections are linked to food and environmental allergies. And, up to 55% of dogs with atopy (caused by environmental allergies) will develop an ear infection.
- Ear mites. Ear mites cause infections by irritating the ear canal and triggering inflammation. They are more prevalent in puppies because they have underdeveloped immune systems. Mites are contagious, so dogs in closer contact with other dogs are at higher risk.
- Moisture trapped in the ear. Because yeast and bacteria thrive in moist environments, dogs who are avid swimmers or are bathed frequently can be at increased risk of developing ear infections.
- Excessive hair in the ear canal. Excessive hair traps moisture and debris, creating an environment hospitable to yeast and bacteria. This tends to be more prevalent in breeds with long, floppy ears, like Cocker Spaniels and Basset Hounds.
- Foreign objects or debris. Foreign objects can cause trauma, while debris traps moisture.
- Underlying skin conditions. These include atopy and seborrhea. Diseases that impact skin quality, including hypothyroidism and Cushing’s disease, can also be a factor.
Product Spotlight: Grooming Tool for Excess Ear Hair
Some breeds naturally grow excessive hair inside the ear canal, which can trap moisture and debris. The Grooming Hemostat Locking Forceps are commonly used by professional groomers to assist with removing loose hair from the outer ear area in breeds prone to heavy hair growth. If you're considering ear hair removal at home, consult your veterinarian or groomer first to ensure it's appropriate for your dog's breed and ear health.
Signs and Symptoms of an Ear Infection
Learning to recognize dog ear infection symptoms and signs will allow you to proactive in seeking veterinary guidance before problems can escalate.
- Head shaking. Dogs will instinctively shake their head in an attempt to relieve the itching and pain and dislodge any gunk in the ear.
- Scratching at the ears. Similar to head shaking, dogs might scratch their ears to relieve the pain, itching, and discomfort.
- Redness or swelling. This is the immune system’s way of responding to inflammation caused by the infection.
- Odor from the ear. The odor is caused by the overgrowth of yeast or bacteria. Yeast infections carry a yeasty odor, while bacterial infections often smell like sewage.
- Discharge. Ear discharge contains a combination of byproducts, including excess ear wax, dead skin cells, and bacteria or yeast. Discharge colors vary based on whether the infection is caused by bacteria, yeast, or mites. For example, yellow generally indicates a possible early bacterial infection. Black ear wax with a coffee ground texture points to ear mites, while dark brown can mean either yeast or mites.
- Sensitivity or pain when touched. Caused by inflammation, even a gentle touch can cause pain or sensitivity.
- Crusting or scabbing around the ear. This is usually caused by a combination of scratching, inflammation, and dried discharge.
Safe At‑Home Care for Mild Ear Irritation
Ask your veterinarian if any of the following at-home evidence-based options are suitable for your dog.
- Gentle ear cleaning. A gentle dog ear cleaning using a commercial veterinary cleanser can help remove moisture and debris and break down wax. In cases of severe ear infections, at-home cleaning can do more harm to your dog’s ear, however. If in doubt, it’s best to check with your veterinarian.
- Wiping the outer ear with a soft cloth or cotton pad. Avoid placing any object into the ear canal, as this can worsen the infection, push debris further into the ear canal, and damage the ear.
- Keeping ears dry. Yeast and bacteria favor moist environments, so keeping the ears dry, like after a bath or swimming session, can help. Use a soft cloth to gently dry the outer portion of the dog’s ear.
- Note that swimming and bathing, unless the head is kept dry, are not recommend for dogs with active ear infections.
- Warm compress. In cases of mild ear infections, a warm compress can help soothe pain and ease inflammation. Never use a hot compress on a dog!
- Preventing scratching. Scratching only worsens the situation. If you’re unable to distract your dog from scratching themselves, you may want to consider purchasing a cone made of soft, comfortable material.
Product Spotlight: Simplify Routine Ear Cleaning
Keeping the outer ear clean can help remove dirt, wax, and debris before they contribute to irritation. The Pet MD Dog Ear Finger Wipes fit over your finger for gentle, controlled cleaning of the outer ear area. They're a convenient option for routine maintenance, especially for dogs prone to wax buildup or those who dislike traditional liquid ear cleaners.
Product Spotlight: Help Reduce Excess Ear Moisture
Moisture trapped inside the ear creates an environment where yeast and bacteria can thrive. The Vet's Best Ear Relief Dry Ear Cleaner is designed to help dry excess moisture after swimming or bathing while supporting overall ear health. For dogs that spend a lot of time in the water, an ear-drying solution may be a helpful addition to your prevention routine.
Dog Ear Infection Home Remedies to Avoid, Per Veterinarians
- Hydrogen peroxide. Although hydrogen peroxide is a mild antiseptic, it’s still too harsh for use on sensitive dog ears. It can irritate the skin, strip away protective oils, and increase inflammation.
- Vinegar or alcohol. These can cause stinging and pain, and damage inflamed ear tissue, especially if the ear is already infected.
- Coconut oil. While coconut oil may have some topical uses for dogs, the ears aren’t one of these. Though coconut oil can help loosen debris, it can also trap moisture.
- Essential oils. Humans use products containing tea tree oil and other types of essential oils, but veterinarians warn that they’re toxic to dogs if ingested, inhaled, or absorbed through the skin.
- Cotton swabs inside the ear canal. The same rule here applies to dogs as it does to humans: inserting a cotton swab too deeply into the ear canal can cause damage and push debris deeper into the ear canal.
- Over‑the‑counter human ear drops. Due to the differences in our respective ear structures and chemistry, ear products made for humans aren’t effective for dogs. They can also irritate sensitive dog ears and worsen infections.
When to See a Vet for Ear Infection
If you notice any of these red flags or anything else out of the ordinary, we recommend contacting your veterinarian.
- Persistent odor or discharge.
- Pain when touching the ear.
- Swelling or redness.
- Head tilt or balance issues.
- Symptoms lasting more than 24–48 hours.
- Recurrent infections.
- Fever, lethargy, or loss of appetite.
Preventing Future Ear Infections
Preventing ear infections is especially important for dogs with floppy ears, prone to developing allergies, or who are frequent swimmers. Ask your veterinarian if the following are appropriate.
Regular ear checks and cleaning. Ask your veterinarian how often your dog needs to have their ears cleaned. Dog ear cleaning isn’t needed for most pups on a regular basis and, in fact, excessively cleaning the ears can lead to infections or damage if done incorrectly.
Managing allergies. Allergies are a leading underlying cause of ear infections in dogs, so addressing them can help prevent the occurrence of ear infections.
Keeping ears dry. Yeast and bacteria thrive in moist environments, so keeping the ear dry is a good way to stop them before they can proliferate. This is especially useful after baths or for dogs who are frequent swimmers. Try using a soft, but sturdy paper towel or a wad of cotton to gently dry the inside of the canal.
Using ear‑drying solutions after swimming. In some cases, using a towel may not be sufficient to remove excess moisture from the ear, so an ear-drying solution may be necessary. As with any product, check with your veterinarian before applying it to your dog’s ears.
Maintaining overall skin health. Aside from treating any skin conditions or allergies, ask your veterinarian if Omega-3 fatty acids, antioxidants, and other supplements designed to support the skin barrier are appropriate for your dog.
If you do notice signs of an ear infection, we encourage you to promptly seek veterinary care. Early intervention means symptoms don’t have an opportunity to worsen. Your veterinarian will also be able to determine the underlying cause of the infection, thus helping to prevent future flareups.
