Usually, there’s an underlying cause for the scratching and head shaking, such as ear mites or bacterial and/or yeast infections of the ear canal. This trauma can cause blood to leave the vessels and pool in a pocket between the skin and cartilage components that make up the outer part of the ear flap. Although both dogs and cats can suffer ear hematomas, the condition is much more common in dogs.Įar hematomas are usually caused by some kind of self-trauma - such as when a pet aggressively scratches at the ears or shakes his or her head, causing the ear flaps to slap against the skull.
