Why do aural (ear) hematomas occur?
Ear hematomas occur when a blood vessel in the ear bursts and bleeds into the space between the ear cartilage and skin. This is most commonly associated with trauma such as scratching or shaking the ears and bite wounds. Dogs with long, floppy ears are at greater risk for developing ear hematomas. Pets with clotting or bleeding disorders may also develop hematomas, with or without a history of trauma.
