How to treat a hematoma on a dog's ear at home?

You can manage a dog's ear hematoma at home by preventing scratching with an E-collar, applying cold/warm compresses to reduce swelling, and keeping the area clean, but a vet visit is crucial to address the underlying cause (like an infection) and prevent permanent "cauliflower ear," as severe cases need professional drainage or surgery to properly heal the skin-cartilage separation. While small ones might resolve, home care focuses on comfort and preventing worsening until veterinary treatment can occur.
