Pets often will 'act out' to tell us they are having health problems.
Keep her ear clean by gently wiping her ear with a water-dampened washcloth - do not dribble anything in into the ear canal. Never use a Q-Tips, but use cotton balls to wipe out the inside the ear.
If she has long fur, it should be trimmed away from the raw areas to prevent it from matting into the wound. Using topical oils should be avoided, this can further irritate the skin and contribute to fur matting.
If she is shaking her head, watch for any swelling of the ear flap - this could be a sign a hematoma is forming. This is is a blood blister forming between layers of the ear tissue and needs to be treated by a vet to decompress it and prevent deformation of the ear.
Good luck with her and keep us updated on her progress :)
