Understanding Ear Hematomas in Dogs: A Comprehensive Guide
Ear hematomas in dogs can cause significant pain and discomfort, and if left untreated, may lead to permanent ear deformity. At the Veterinary Medical Center of Indian River County, we specialize in diagnosing and treating ear hematomas to relieve your pet’s discomfort and prevent future complications.
This guide explains what ear hematomas are, why they occur, treatment options, and how to prevent them from developing in the future.
What is an Ear Hematoma?
An ear hematoma is a pocket of blood that forms between the skin and cartilage of a dog’s ear flap (pinna). It typically results from blood vessel rupture, leading to swelling, warmth, and discomfort. The ear may appear swollen, soft, or fluid-filled, and without treatment, it can harden into a “cauliflower ear” deformity.
In severe cases, the built-up pressure may cause the hematoma to rupture, resulting in a sudden, messy burst of blood—something no pet owner wants to experience.
Common Causes of Ear Hematomas in Dogs
Hematomas do not just appear randomly—they are usually a result of an underlying condition that leads to excessive ear scratching or head shaking.
Primary Causes:
- Ear Infections – Bacterial or yeast infections cause intense itching, leading to head shaking and scratching, which increases the risk of hematomas.
- Allergies – Allergic reactions to food, pollen, or environmental irritants cause ear inflammation and itching, leading to excessive scratching.
- Physical Trauma – Dog fights, rough play, or accidents can directly damage the ear, causing blood vessels to rupture.
- Parasites – Ear mites, fleas, or ticks cause irritation, making dogs scratch aggressively.
Addressing these underlying conditions is key to preventing recurring hematomas.

Signs That Your Dog May Have an Ear Hematoma
Recognizing an ear hematoma early can prevent further complications. Watch for:
- Swelling – A fluid-filled bump or large swollen area on the ear flap
- Discomfort – Frequent head shaking, scratching, or pawing at the ear
- Pain and Sensitivity – Dogs may yelp or pull away when the ear is touched
- Changes in Behavior – A typically playful dog may become lethargic or irritable due to pain

When to See a Veterinarian
You should seek veterinary care immediately if you notice:
- A large or rapidly growing swelling
- Signs of infection (redness, warmth, or foul-smelling discharge)
- Your dog avoiding food or activity due to discomfort
- A previously treated hematoma returning
Early treatment reduces pain, prevents complications, and may avoid the need for surgery.
How Are Ear Hematomas Diagnosed?
Your veterinarian will:
- Perform a physical exam to assess the swelling and check for pain
- Use an otoscope to examine the ear canal for infections or foreign objects
- Run diagnostic tests (ear cultures, skin scrapings, or allergy tests) to identify underlying conditions
Treatment Options for Ear Hematomas
Surgical Treatment
The preferred treatment for moderate to severe hematomas is surgery, which:
- Drains the fluid and prevents it from re-accumulating
- Sutures the ear flap to promote healing and maintain the natural shape
- Reduces recurrence risk compared to non-surgical methods
After surgery, drains may be placed to prevent fluid buildup. Stitches are typically removed after two to three weeks.
Non-Surgical Treatment
- Needle Aspiration – Extracting the fluid with a syringe (may refill within days)
- Corticosteroid Injections – Help reduce swelling but do not prevent reoccurrence
- Medical Management – Treating the underlying cause (ear infections, allergies, etc.)
Hematomas often return quickly after aspiration unless the underlying issue is treated.

Home Care and Post-Treatment Recovery
After treatment, proper home care is essential to promote healing and prevent infection.
Post-Treatment Tips:
- Administer all prescribed medications (antibiotics, pain relievers, anti-inflammatories)
- Prevent scratching with an Elizabethan collar (E-collar)
- Clean the ears regularly using vet-recommended solutions
- Monitor for swelling or infection (report any concerns to your vet)
Recovery time varies between two to four weeks depending on the treatment method.
Preventing Ear Hematomas in Dogs
The best way to prevent hematomas is to reduce ear irritation.
- Regular ear cleaning – Prevents infections that cause head shaking
- Allergy management – Controls inflammation and reduces ear scratching
- Routine vet visits – Early detection of infections, mites, or allergies
- Avoid rough play – Especially for dogs prone to ear trauma

FAQs About Ear Hematomas in Dogs
Can ear hematomas heal on their own?
Most hematomas persist and worsen without treatment.
Is surgery always necessary?
Surgery is recommended for large or recurring hematomas. Smaller hematomas may respond to aspiration and steroids, but recurrence is common.
How long does it take for a dog to recover after ear hematoma treatment?
Two to four weeks, depending on the treatment method and underlying cause.
