Breeds like Basset hounds are prone to this condition.

  • Swelling: The affected ear will appear noticeably swollen due to fluid between ear cartilage, and the swelling can vary in size depending on the severity of the hematoma.
  • Thickening: The ear flap may feel thicker or more distended compared to the unaffected ear. This is due to blood clots.
  •  Warmth and pain: Like ear infections, the ear may feel warm to the touch and be sensitive or painful for the dogs when touched.
  •  Head-Shaking and Dog Excessively Scratching: Dogs with ear hematomas blood clots often exhibit increased head shaking, tilting head sideways, or scratching at their ears due to discomfort.
  •  Ear Drooping: In some cases, the ear flap may droop or hang down due to the accumulation of fluid and underlying infections. This results in floppy ears.

Dog Ear Hematoma Treatment – How Do You Treat Ear Hematomas in Dogs?

Treating a hematoma on a dog’s ear typically involves draining the accumulated blood or fluid and addressing the cause to prevent recurrence.

It’s essential to consult with a veterinarian for a proper diagnosis and to determine the most suitable course of treatment for underlying ear infections and hematomas in dogs and your dog’s specific condition. Here’s a general overview of how an ear hematoma is treated:

Veterinary Examination

 The first step is to take your dogs to a veterinarian for a thorough examination. The vet will assess the hematoma’s severity, check for any underlying infections or other issues, and determine the best treatment option for ear hematomas in dogs.

Draining the Hematoma

 To relieve pressure and promote healing, the veterinarian will likely drain the fluid from the hematoma using a small incision. This is one of the conventional treatments.

 This procedure is usually performed under local anesthesia to ensure your dog’s comfort during the process. The vet may use a syringe or make a small incision in the localized mass to remove the accumulated fluid from the blood blister. They may also perform a needle aspiration.

Compression Bandaging

 After draining the hematoma, the vet may apply a compression bandage to the ear. This bandage helps reduce further swelling and encourages the ear to heal properly. The bandage must be properly secured around the whole ear flap but not too tight to avoid cutting off blood flow.


 Depending on the severity of the hematoma and the cause, the veterinarian may prescribe medication to manage pain and inflammation. Antibiotics might be prescribed if an ear infection is present.

E-Collar (Cone)

To prevent the dog from scratching or shaking its head, which can aggravate the hematoma, the vet may recommend that pet parents place an e-collar (also known as a cone or Elizabethan collar) over their pet’s head during the healing process until it eventually reabsorbs.

Follow-Up Care and Prevention

 Follow your veterinarian’s instructions regarding wound care, medication administration, and bandage changes. Attend any follow-up appointments to ensure the hematoma is healing properly and to address any concerns.

Addressing the cause of the hematoma (ear mites, infections, etc.) is essential to preventing its recurrence. If an ear infection, allergies, or other issues are contributing to the hematoma, your vet will devise a treatment plan to manage larger hematomas and resolve these problems to prevent blood filling it back.

It can cause chronic ear infections too or rupture of blood vessel, further injury, and other obvious trauma.

Without proper treatment, aural hematomas can take a long time to heal, result in scar tissue on the skin, and there’s a high chance that it will reoccur or lead to complications.

Home Treatments and Medication

In some cases, your vet might recommend using an e-collar (cone) to prevent the dog from excessive scratching or shaking their head excessively during the healing process.

Depending on the severity of the hematoma and the underlying cause, they may also prescribe medication or suggest topical treatments to aid in the healing process to prevent scar tissue.

How Long Can You Leave a Hematoma on a Dog’s Ear?
