It's a simple potion: 3 parts each water and white vinegar and 1/2 part hydrogen peroxide. Put it in a squeeze bottle. Gently squeeze it into the ears while playing with them and praising the dog. Massage the base of each ear.Let the dog shake his head,then wipe out the excess with a cotton ball. Never use cotton swabs, only cotton balls.

Repeat as needed.

You might want to do this in the bathroom or outside because it can get messy.
