Q. My dog has a fluid sack on the outside of right ear

Answered By
ANGEL ALVARADO

A. If the ear flap itself looks like a small pillow, it is likely an aural hematoma. A blood vessel in the ear flap has ruptured causing the flap to fill with blood and give the pillow appearance. These are most commonly caused by head shaking which in turn is caused by an ear infection. Treatment is surgical. Your vet will open the flap and drain the blood then suture the ear flap together to prevent further hemorrhage. Afterwards, treating any underlying infection should prevent head shaking. The ear can be drained with a syringe but it usually refills requiring repeated draining and leading to a potentially deformed ear flap
