Aural haematoma in dogs

Written by Kelsey | September 17, 2026

An aural haematoma in dogs, also known as a blood-filled ear, occurs regularly, especially in dogs with floppy ears or sensitive skin. It usually looks quite noticeable: the ear is swollen, warm and feels soft, as though it is filled with fluid. Similar to a blister. Many owners wonder whether an aural haematoma in dogs is dangerous, whether you need to intervene or whether it will resolve on its own. In this blog, we tell you everything about the causes, treatment and experiences of aural haematomas in dogs.

What is an aural haematoma in dogs?

An aural haematoma develops when small blood vessels in the ear flap rupture. This often happens due to vigorous head shaking or scratching at the ear, for example because of ear inflammation, itching or a foreign object in the ear. Blood collects between the skin and cartilage, resulting in a painfully swollen ear.

This is also known as an aural haematoma.

Aural haematoma in dogs: what causes it?

The most common causes of an aural haematoma in dogs are:

Ear inflammation or ear infection
Excessive itching due to allergies or parasites (such as ear mites)
Trauma, for example from a blow or impact
Excessive head shaking

Please note: without treatment, the ear may become permanently deformed. This is also known as cauliflower ear in dogs.

What are the options for treating an aural haematoma?

Treatment depends on the severity of the aural haematoma. In some mild cases, the body can gradually break down the blood, but medical intervention is often necessary.

Can you treat an aural haematoma in dogs yourself?

Many people look for ways to treat an aural haematoma in dogs themselves, but this is usually not sufficient. Home treatment with natural remedies, such as an ointment or lotion containing arnica, may help with swelling and tenderness in mild cases, but it is not a substitute for medical treatment.

Always consult a vet if you are unsure.

Treatment by the vet

The vet assesses how the aural haematoma should be treated. There are several methods. It may be drained with a needle, flushed or treated surgically. Surgery may be necessary for a larger or recurring aural haematoma.

Aural haematoma surgery in dogs

During surgery on your dog’s aural haematoma, the accumulated blood is removed. The ear is then often secured with sutures and a special bandage to prevent it from filling up again. A head bandage is also often applied to keep the ear firmly in place. For additional protection, you can use the MPS Headcover.

Frequently asked questions

Should you massage your dog’s aural haematoma or not?

Massaging an aural haematoma in dogs is not recommended because it may worsen the injury or cause more blood vessels to rupture.

Can you cool an aural haematoma in dogs?

In the early stages, briefly cooling the aural haematoma with a cold pack or wet cloth may provide relief. Always wrap the cooling aid in a cloth to avoid direct contact with the skin.

Cost of treating an aural haematoma in dogs

The cost of treating an aural haematoma in dogs can vary depending on the chosen method (needle aspiration, drain or surgery) and aftercare. Always ask your vet for a cost estimate in advance.

Is an aural haematoma in dogs dangerous?

An aural haematoma is usually not life-threatening, but it can be very painful and often leads to permanent damage to the ear if left untreated. It is therefore important not to wait too long and to consult a vet.

Will an aural haematoma in dogs resolve on its own?

In mild cases, an aural haematoma may shrink spontaneously, but there is a high risk of recurrence or permanent deformation of the ear. Scar tissue can cause the ear to become misshapen, which is also known as “cauliflower ear”. This is not only less attractive, but may also affect hearing and ventilation of the ear. In addition, the underlying cause often remains present (such as an ear infection or allergy).

Aural haematoma in dogs, owners’ experiences

Many dog owners report that their dog recovered quickly after treatment. However, a common mistake is waiting too long in the hope that it will resolve on its own. Prompt treatment helps prevent complications.

Practical recovery tips

Prevent head shaking: use a protective collar or bandage if necessary.
Check the ear daily for new swelling or signs of inflammation.
Treat the cause: ask the vet to check for ear mites, inflammation or allergies.
Only use products recommended by your vet, even if you are considering natural remedies such as arnica.

In summary

An aural haematoma in your dog requires careful assessment and treatment by a vet. Although it may look harmless, it can cause considerable discomfort. Look out for the symptoms, seek timely treatment and prevent permanent damage to the ear.
