Ear Hematomas in Dogs and Cats

What They Are, Why They Happen, and Why Home Remedies Can Do More Harm Than Good

If your dog or cat suddenly has a swollen, squishy ear flap that feels like a water balloon, they may have an ear hematoma. This condition occurs when blood vessels inside the ear burst—usually from intense scratching or head shaking—causing blood to collect between the layers of the ear flap (also called the pinna).

While it may look alarming, ear hematomas are treatable. However, how they’re treated makes all the difference in healing, comfort, and preventing future problems.

What Causes an Ear Hematoma?

  • Excessive scratching from ear infections, mites, or allergies
  • Frequent head shaking due to irritation or discomfort
  • Trauma to the ear (e.g., from rough play or scratching against objects)
  • Underlying ear issues, like yeast or bacterial infections

The pressure causes blood vessels in the ear to rupture, leading to swelling and discomfort. If left untreated, it can harden and cause permanent ear deformity (often called “cauliflower ear”).

Why You Shouldn’t Try to Treat It at Home

  • Do NOT try to drain the ear yourself – Puncturing the ear at home can lead to severe infection, uncontrolled bleeding, and further damage. It won’t solve the underlying issue and may make things worse.
  • Avoid internet “DIY fixes” – Wrapping the ear, using over-the-counter creams, or waiting it out may lead to scarring, long-term pain, or repeat hematomas.
  • Don't ignore the cause – The hematoma is a symptom. If you don’t treat the underlying infection, mites, or allergies, it will likely come back.

Veterinary Treatment Options

At Whittington Veterinary Clinic, we treat ear hematomas with your pet’s comfort and long-term ear health in mind. Depending on the severity and cause, treatment may include:

  • Surgical drainage and repair – To remove blood, prevent recurrence, and preserve the shape of the ear
  • Needle aspiration – In mild cases or when surgery isn’t ideal (may require multiple visits)
  • Treatment of the underlying cause – Including ear cleaning, infection control, allergy management, or parasite treatment
  • Pain relief and anti-inflammatories – To keep your pet comfortable and reduce swelling
