Dog ear hematoma is a surprisingly common but often misunderstood condition among pet owners. If your dog suddenly has a swollen, puffy ear flap that feels like a water balloon, you’re likely dealing with an ear hematoma. This condition can be painful, and if left untreated, it may lead to permanent ear deformity. In this expert 2025 guide, we’ll walk you through the causes, symptoms, treatment options, and how to prevent ear hematomas in dogs — helping you act fast and keep your dog comfortable.

What Is a Dog Ear Hematoma?
A dog ear hematoma, also called an aural hematoma, is a swelling caused by blood pooling between the skin and cartilage of your dog’s ear flap (pinna). It usually occurs suddenly and is most often seen in floppy-eared breeds, though it can affect any dog.
The most noticeable sign is a soft or firm lump on the ear, often warm and tender to the touch. The ear may hang differently or appear misshapen. If left untreated, scar tissue can form, leading to a permanent “cauliflower ear” appearance.
Common Causes of Ear Hematomas in Dogs
The underlying cause of a dog ear hematoma is usually self-inflicted trauma. When dogs shake their head vigorously or scratch their ears excessively, small blood vessels inside the ear flap can rupture, leading to a hematoma. But what triggers that behavior?
- Ear infections: One of the most common triggers; irritation causes scratching and head-shaking
- Ear mites or parasites: Especially common in puppies and outdoor dogs
- Allergies: Can lead to itchy ears and repeated trauma
- Foreign objects in the ear: Grass seeds, dirt, or debris can cause discomfort
- Injury or rough play: Direct trauma from bumping or roughhousing may also cause vessel rupture
To effectively treat an ear hematoma, it’s critical to identify and resolve the underlying issue — otherwise, the problem is likely to return.
Symptoms to Watch For
Early recognition of a hematoma can save your dog discomfort and prevent costly complications. Here’s what to look for:
- Swelling on one ear flap (soft or firm)
- Ear feels warm and slightly squishy
- Dog shaking head more than usual
- Visible discomfort or pawing at the ear
- Ear may droop or look asymmetrical
If you notice these signs, contact your veterinarian promptly. Delaying treatment can result in permanent disfigurement and chronic pain.
Treatment Options for Dog Ear Hematomas
The best treatment for a dog ear hematoma depends on the severity of the swelling, the dog’s health, and the underlying cause. Most cases require veterinary attention, especially to prevent recurrence or scarring. Here are common options:
- Surgical drainage: A small incision is made to remove the blood; sutures may be placed to prevent refilling
- Needle aspiration: Less invasive but often temporary; fluid is drawn out with a syringe
- Cannula placement: A small drain left in place to allow continuous fluid release
- Treating the root cause: Antibiotics, antiparasitic meds, or anti-inflammatory drugs may be prescribed
According to PetMD, surgery remains the most effective solution, especially for large or chronic hematomas.
Healing and Recovery Timeline
Recovery from a dog ear hematoma depends on treatment type and whether complications arise. Here’s what to expect:
| Treatment | Recovery Time | Notes |
|---|---|---|
| Surgical drainage | 2–3 weeks | Sutures may stay in for 10–14 days |
| Needle aspiration | Few days | Often needs multiple sessions |
| Drain with cannula | 1–2 weeks | Daily cleaning required |
Be sure to follow your vet’s instructions and use an Elizabethan collar if needed to prevent scratching. You may also want to explore our natural remedies for itchy ears to help with underlying issues. Dogs prone to ear hematomas may also experience chronic skin irritation.
How to Prevent Dog Ear Hematomas
While not all ear hematomas are preventable, you can reduce the risk by managing the root causes. Dogs prone to ear problems benefit most from consistent ear hygiene and parasite control.
- 🧼 Clean ears regularly: Use vet-approved solutions to avoid buildup of wax and debris
- 🦟 Prevent parasites: Use monthly flea and mite treatments
- 🚫 Address allergies promptly: Work with your vet to control skin and food allergies
- 🩺 Check ears weekly: Look for redness, odor, or excessive head shaking
- 🎾 Limit rough play: Especially if your dog has a history of ear trauma
FAQ
Can a dog ear hematoma heal on its own?
In some mild cases, yes — but most will worsen without treatment and can cause permanent damage.
Is surgery the only option?
No. Aspiration and drains are alternatives, but surgery is usually the most reliable and long-lasting treatment.
How can I tell if it’s a hematoma or infection?
Hematomas cause swelling in the ear flap, while infections are deeper in the ear canal and often smell bad. Sometimes both occur together.
Will my dog be in pain?
Yes, hematomas can be uncomfortable. Immediate veterinary care helps relieve pain and speed up healing.
Final Thoughts
A dog ear hematoma can look alarming, but with fast action and proper care, your dog can recover fully and comfortably. If you notice swelling, don’t wait — contact your vet, treat the underlying issue, and follow up with at-home care to prevent recurrence.
