Our dog's ears filled with blood from head shaking or scratching at different times. Two surgeries were used to repair the hematomas. The first used standard stitches and the 2nd used buttons. The buttons were more comfortable during the healing. See below for more information on ear hematoma cause and repair.

Floppy-Eared Dogs Need Extra Help to Avoid Ear Hematomas
By Dr. Becker

Ear or aural hematomas are fluid-filled pockets on the inside of the earflap.
There are tiny blood vessels in the pinna or the floppy part of your pet's ears.
When something causes these little vessels to rupture, they bleed under the skin and form a fluid-filled pocket.
Ear hematomas are most commonly seen in floppy-eared dogs, but they can occur in any breed of dog – whether their ears are floppy or not – and even occur in cats.
How Ear Hematomas Develop
Most dogs develop ear hematomas from shaking their heads or chronically scratching at their ears.
Dogs shake their heads a lot.
They shake after baths. Sometimes they try to shake themselves dry.
Other times the ear is bothering them, which could be an allergic response that is causing intense itching in the ears, or it could be an ear infection.
Shaking the head alone can cause those tiny blood vessels to burst, but so can smacking the ear against something while shaking.
Trauma to the ear can cause bleeding as well.
Other causes of ear hematomas are injury to the earflap (usually from a dogfight), infection or inflammation of the ear, presence of a foreign body, or even a parasite in the ear.
Once bleeding under the skin begins, it creates irritation, which will make your dog shake his head even more. If the problem isn't addressed and blood and other fluids continue to accumulate in the skin, the hematoma can become quite large, even to the point of blocking off the opening of the ear canal.
It's not uncommon for ear hematomas to rupture while the dog is shaking his head, spraying blood all over the place. Hopefully, pet owners don't let ear hematomas get to this point.
