What Causes Wounds on Dogs' Ears?

📅 October 07, 2026⏱ 2 min read

Have you noticed your dog scratching its ears or seen a wound on its ear? Don't panic; ears can get irritated for several reasons, but with the right knowledge, you can address the issue. Let's explore the common causes and how to handle them.

Why Do Dogs Get Wounds on Their Ears?

1. Fleas and Ticks

Fleas and ticks are notorious for causing ear infections and irritation. These tiny pests can introduce bacteria into the ear, leading to swelling and pain. You might notice your dog shaking its head or tilting its head to one side, which is a sign of ear irritation.

#### How to Handle It

Regularly check your dog for fleas and ticks, especially during warmer months. Use a flea and tick preventative product, such as Seresto Flea & Tick Collar, which provides up to 8 months of protection. Keep your dog's environment clean and consider using a natural flea repellent, like Flea & Tick Repellent Spray for Dogs.

2. Ear Infections

Ear infections are common and can be caused by bacteria or yeast. Dogs with floppy ears are more prone to ear infections because air doesn't circulate well in their ear canals. Signs include redness, odor, or a dark, waxy substance in the ear.

#### How to Handle It

If you suspect an ear infection, take your dog to the vet. They may prescribe ear drops or tablets to clear up the infection. In the meantime, clean the ear gently with a vet-recommended ear cleaning solution, like Ear Cleanser for Dogs.

3. Allergies

Allergies can cause skin reactions, including ear irritation. Common triggers include food allergies, environmental allergens, and even flea bites. You might see redness, itching, or even hair loss around the ear.

#### How to Handle It

Identify and remove any known allergens from your dog's environment. Switch to a hypoallergenic dog food, like Hill's Science Diet Adult Sensitive Skin & Stomach, and use a flea control product to minimize the chances of flea bites.

4. Foreign Objects

Sometimes, dogs can get grass, dirt, or other small objects stuck in their ears. This can cause discomfort and potentially an infection if left untreated.

#### How to Handle It

Use a soft cloth or cotton swab to gently clean the outer ear, but avoid inserting anything into the ear canal. If you can't remove the object or if your dog is in pain, seek veterinary help immediately.

5. Ear Mites

Ear mites are tiny parasites that live in the ear canal. They can cause intense itching and lead to ear infections. Your dog might scratch its ear, shake its head, or produce a dark, waxy discharge.

#### How to Handle It

Your vet will diagnose ear mites with a simple ear swab test and prescribe a treatment, such as Revolution for Dogs. Follow the instructions carefully and recheck your dog's ears after treatment.

Preventative Measures

To keep your dog's ears healthy, practice regular ear cleaning. Use a solution suitable for dogs, such as Ear Cleaner for Dogs, and clean the outer ear canal weekly. This can help prevent the buildup of wax and reduce the risk of infections.

Additionally, keep your dog away from areas where ticks and fleas are common, such as grassy fields and dense underbrush. Regular vet check-ups can also help catch any potential issues early.

By understanding the common causes of ear wounds and taking proactive steps, you can ensure your dog stays healthy and comfortable.
