I've found bandaging an ear after an ear hematoma repair to be a challenge. I've been using stretch net sleeves to allow air to get into the canal of the ear that we bandage over the head. However, the sleeve has been difficult to tape in place. Taping the cranial edge to the dog's head has not been a problem, but securing the caudal edge with tape is not ideal since the sleeve tends to creep forward with the loose skin on the neck. Cutting small slits through the stretch net sleeve and feeding the collar through it solves this problem.
