Ear hematomas in dogs usually take about half a month to a month to heal on their own, but the risk of recurrence is high because the inflammation is likely to persist even though the blood in their ears is slowly absorbed by the body. If your dog’s ear hematoma does not heal on its own, you need to take your dog to the doctor promptly. Persistent inflammation can cause ongoing damage to the dog’s ear, and even if it heals in the short term, it can recur frequently and even cause a variety of systemic complications. So dogs with ear hematomas are advised to go to the hospital for prompt treatment.
