In this article, our experienced veterinarian Dr. Chyrle Bonk walks you through common causes of scabs on a dog’s ears, what they look like, and how to treat them.
Common causes of scabs on a dog’s ears
Scabs on a dog’s ears can appear differently depending on what is causing them. So, let’s take a look at the most common (with pictures) and what you can do about them.
1. Allergies causing excessive ear scratching
Dogs can develop allergies to things in their environment as well as to ingredients in their food. Both types of allergies can lead to skin that is dry, itchy, and inflamed. Dogs may also develop chronic ear infections with allergies. The combination of an ear infection and itchy skin can leave some dogs scratching or rubbing their ears, creating scabs on the ear flaps as well as under the flap near the ear canal. See picture below for an example:
Signs that your dog has allergies: Dogs may also be itchy or have a rash in their ears or on other areas of their body, have a smelly discharge from their ears, or frequently shake their head.
How it is treated: Allergies are best treated by removing the allergen from a dog’s environment or diet, if possible. Since this can’t always happen, the next best treatment is antihistamines and anti-inflammatories, as well as treating any ear infections or scabs with topical antibiotics, antifungals, or anti-inflammatories.

2. Ear Infections
This was covered a bit in the allergies section, but not all ear infections stem from allergies. Ear infections may be common in pups with floppy or heavy ears. Think Basset Hounds, Golden Retrievers and Cocker Spaniels. Bacteria and yeast love to grow where it’s dark, warm, and moist, some things that these floppy ear flaps provide in the ear canal.
Signs that your dog has an ear infection: When bacteria or yeast reproduction goes into overdrive in these ideal conditions, they create an itchy, smelly mess in the ear that your dog wants nothing more than to scratch. It’s the scratching that creates scabs on their ear flaps or on the base of the ear. You may also notice a smelly discharge, head tilt, and lots of head shaking (even when their ears are clean).
How it is treated: Veterinarians will treat ear infections by cleaning and the application of antibiotics or antifungal ointments. View pictures of common ear infections, with veterinarian advice, or home remedies for ear infections.
3. Parasites (Mites and Fleas)
Our poor pups are subject to many types of external parasites, including fleas, scabies (mange), and ear mites. All of these are capable of creating scabs on the ears.
Mites/Mange: Sarcoptic mange is a mite infestation that is contagious and acquired through contact with the mites in the environment or from another animal (e.g., fox, coyote, other dog). These infestations are very itchy, and excessive scabbing of the skin is common. The most common areas affected are the ear flaps (margin), elbows and hocks (ankles), as pictured below.
Fleas: Fleas cause irritation to the skin when they bite. Some dogs are especially sensitive and even allergic to flea saliva, causing an itchy mess that can lead to scabs when they scratch, as shown on the images below:
Mites and mange can also invade the skin, causing itching, skin inflammation, and hair loss. Ear mites like to target the ear canal, similar to an ear infection, and some types of mange prefer to live on the face. The ears may not be the only areas affected. Hair loss and scabs may occur anywhere on the body.
How it is treated: Your veterinarian will be able to diagnose external parasites with skin scraping. Most are treated with an antiparasiticide in the form of a bath, topical, or oral medication.
4. Injury
Injuries to ear flaps are common, especially if you have a puppy in your home. Ears can make the perfect chew toys, catch on things, or be affected by frost bite. With skin-breaking injuries come scabs. There may also be bleeding, swelling, redness, or bruising. Plus, injured ears are going to hurt. Dogs may shake their head, whine or cry when their ears are touched, or develop a secondary infection with a smelly, yellow discharge.
How it is treated: Gently cleaning an ear injury is the first step. From there, depending on the severity, you may need to have the wound stitched, wrapped, antibiotics, or other ointments to promote healing.
5. Seborrhea
Seborrhea is a disorder of the keratinization process where the outer layer of skin continuously renews itself. It can lead to scaly, greasy skin, often at the margins of the ears. Along with this excessive buildup of greasy scales, the skin can also become inflamed and infected, potentially leading to scabs on the ears and other areas of the body.
How it is treated: There is no cure for seborrhea, but it can be managed with shampoos and medications to help remove the scales and reduce inflammation.
6. Other causes of ear scabs
Some other causes of scabs on a dog’s ears include the autoimmune disease pemphigus foliaceus, which can cause hair loss, scabs, and other sores on the face, neck, and ears. Treatment requires immune suppression with medications.

Sunburn can also cause scabs on the ears, especially if the skin is damaged enough to blister. Sunburns happen more often in dogs with lighter-colored hair, and it may affect other lightly-haired parts of the body, including the nose and belly.
Lumps and bumps on the ear flap may also appear as scabs. Pictured below are benign warts on a dog’s ear flap:

Most ear scabs do not heal on their own.
Most of the time, scabs on your dog’s ears aren’t going to go away on their own. They will need some form of treatment to clear them up. In order to get the right treatment, you’ll need the right diagnosis, which most often will require veterinary care.
At-home care (if your dog is not showing other signs of illness)
If your dog is experiencing any other issues, such as not eating, weight loss, extreme itchiness, a smelly discharge, or severe discomfort, see your veterinarian immediately. If they are only having mild discomfort without other signs, you may try some at-home treatments first, as discussed below.
You’ll want to get a proper diagnosis before proceeding with any treatment; As with any other dog health issue, the treatment for scabs on a dog’s ears will be directly related to the cause.
– Make sure your pup is up to date on their flea treatment. Steer clear of over-the-counter products as most aren’t as effective or safe as those you get from your veterinarian. This will help to rid your pup of any external parasites that could be causing scabs on their ears.
– Check their ear canals for discharge. You can also clean the ears with a veterinary ear cleaner to help remove any excess gunk that could be causing itchiness. Of course, if the ear is red and inflamed, see your veterinarian.
– Gently clean any bite wounds or lacerations with mild soap and warm water. Apply a triple antibiotic ointment if the wound is minor. More severe wounds will need veterinary treatment.
Veterinary diagnosis and treatment
If your best at-home efforts aren’t showing some positive results within a day or two, or your pup is showing any signs, see your veterinarian. They may do some skin scrapings, ear swabs, or even bloodwork to determine the cause of your dog’s ear scabs. From there, they may prescribe antiparasiticides, antibiotics, anti-inflammatories, or a novel protein diet to help heal your dog’s ear scabs.
