There are a number of conditions that cause scabs on the ears. These can include allergies, parasites, skin conditions, and a number of other things.
If a dog is allergic to something, it will get an inflammatory reaction in the ear and the edges of the ear flap will appear as scabs. This is often seen in specific breeds, like Labradors and Boxers, as well as with a type of dermatitis called atopic dermatitis.
Fleas, worms and mites can cause the skin in your ear to become inflamed. They can also spread bacteria, which can infect the ear canal and create an infection.
Ear mites can also invade the ear canal and cause inflammation, irritation, itching, and scabs. These may be itchy, red, or scaly and can sometimes lead to hair loss on the ears.
Atopic dermatitis is one of the most common forms of eczema, and it can affect both the outside and inside of your ear. The ear becomes red, itchy, flaky and dry.
Fungal ear infections can also cause itchy, red and dry ears. They can also cause an itch that's worse at night.
Psoriasis is a chronic skin condition that can also affect the ears, causing itching and inflammation. There are a number of treatments to help with this condition, but it's important to see your doctor if you notice any new scabs.
A cholesteatoma is an abnormal collection of skin cells deep inside your ear, and they can block out light and sound. If they get infected, they can damage the inner ear and brain and lead to meningitis or other serious problems. They're rare but can be easily treated if they're found early.
