Work with her daily by touching her ears a part of a massage routine. To clean the ears, I put my boys on the counter. They have learned to stand still for most grooming. Putting solution in the ear feels funky, so they do squirm. I immediately start massaging the base of the ear and this helps calm them down. Then I let them go and rub their faces like crazy on the couch.
When they finish, I have to comb their faces.
