Dog Ear Hematoma

A swollen, blood-filled ear flap can be alarming to see. If your dog’s ear suddenly looks puffy, soft, thick, or balloon-like, an aural hematoma may be the cause.

An aural hematoma forms when blood collects between the layers of the ear flap. This often happens after repeated head shaking or scratching damages small blood vessels inside the ear. The swelling may involve part of the ear flap or nearly the entire ear.



For families in Akron, Fairlawn, and Copley, a dog ear hematoma is a common reason for urgent veterinary visits. At Copley Fairlawn Veterinary Clinic, we evaluate the swelling itself and also look for the underlying reason your dog is shaking or scratching.

What an Ear Hematoma Looks Like  

An ear hematoma usually causes visible swelling of the ear flap. The affected ear may look thick, rounded, or filled with fluid. It may feel soft, warm, or firm depending on how much blood has collected and how long the swelling has been present.

Many dogs also show signs of ear discomfort. They may shake their head, scratch at the ear, hold the ear differently, or resist having the area touched.



A dog swollen ear flap should be evaluated because the swelling can be painful and may worsen if the underlying ear problem continues.

Why Aural Hematomas Happen  

Aural hematomas often develop after repeated head shaking or scratching. The movement causes small blood vessels in the ear flap to rupture, allowing blood to pool under the skin.

Common triggers include ear infections, allergies, ear mites, foreign material in the ear canal, skin irritation, or trauma. Some dogs with floppy ears may be more noticeable when swelling develops because the ear flap changes shape quickly.



The hematoma is usually not the original problem. It is often a result of irritation deeper in or around the ear.

Why the Underlying Ear Problem Matters  

Treating only the swelling without identifying the cause may lead to recurrence.

If an ear infection is present, your dog may continue shaking the head after the hematoma is drained or repaired. If allergies are driving chronic ear inflammation, the ear may remain itchy unless the allergy component is managed.



During the exam, your veterinarian will inspect the ear canal when possible and check for discharge, odor, redness, debris, or pain. Testing may be recommended to identify bacteria, yeast, mites, or inflammation.

Routine Wellness Exams can also help identify recurring ear inflammation before it progresses into more painful problems.

Is a Dog Ear Hematoma an Emergency?  

An ear hematoma is usually not life threatening, but it should not be ignored. The swelling can be painful, and untreated hematomas may heal with scarring or permanent thickening of the ear flap.



Same-day or prompt care is recommended if the swelling appears suddenly, your dog is very painful, there is heavy head shaking, the ear canal has discharge or odor, or your dog seems unable to settle.

If the ear is bleeding, severely painful, or associated with trauma, urgent care is appropriate.

Our Emergency Vet services can help when ear swelling, pain, or injury develops suddenly.

What Treatment May Include  

At the visit, your veterinarian will examine the ear flap and ear canal. If infection or inflammation is present, ear medication may be prescribed. Pain control may also be recommended because hematomas can be uncomfortable.



If surgery is needed, your dog may require anesthesia or sedation. The ear is treated to remove the trapped blood and reduce the pocket where fluid has collected. Sutures or a protective bandage may be used depending on the technique.

The treatment plan is based on your dog’s comfort, ear health, and recurrence risk.

Recovery After Ear Hematoma Treatment  

Recovery usually includes keeping your dog from scratching or shaking excessively while the ear heals. An e-collar may be needed to protect the ear.

If sutures or a bandage are placed, follow-up visits are important. Your veterinary team will check healing, monitor swelling, and confirm the underlying ear condition is improving.



Some dogs need continued ear medication if infection or allergies contributed to the hematoma. Treating the root cause helps reduce recurrence.

Can an Ear Hematoma Come Back?  

Yes. A hematoma can recur, especially if the underlying ear irritation is not controlled.

Dogs with chronic allergies, repeated ear infections, or frequent head shaking may be more likely to develop another hematoma. Long-term ear care may include allergy management, routine ear checks, and prompt treatment when itching or infection returns.



Early care for ear irritation is often the best prevention.
