My dog has this big squishy lump on his ear, looks like it's full of fluid. Should I be worried about that?

Yesterday, I noticed that my dog has developed a big, squishy lump on his ear that feels like it's full of fluid. I’m not sure how or when it appeared, but it doesn't seem to be causing him any pain. Should I be worried about this lump, or is it something that can wait before seeing a vet?

Answer

Your dog may have developed aural hematoma, a common condition where fluid collects in the ear flap, possibly due to trauma or excessive scratching. While it might not be painful now, it usually requires veterinary attention to prevent complications.

  • Aural hematoma: a fluid-filled swelling in the ear flap
  • Not usually emergency but needs evaluation
  • Commonly requires treatment to avoid discomfort and infection

An aural hematoma occurs when blood vessels in the ear flap rupture and leak fluid, causing the soft swelling you’re observing. Although it’s not typically painful at first, if left untreated, it can become uncomfortable and lead to ear infections or permanent changes to the ear’s structure. A veterinarian will likely evaluate the cause of the hematoma and recommend an appropriate treatment plan, which may include draining the fluid or surgically correcting the issue to prevent recurrence.
