We used to squirt some solution (store brand) into Bambi ears but she hated it and the outside of her ears would get soaked. I don't like a lot of moisture because that can contribute to the yeast problem. Now, I microwave the bottle for like 6 seconds (make sure to test it on your hand before using it!). Nobody likes cold solution in their ears. I halve a cotton ball and then wet it and put it in her ear (holding on to the end), and get it as far in as it will go and then move it around as much as possible. I do that 3-4 times each ear. It works great and she doesn't mind whatsoever, plus the outside of her ears stay nice and dry. To finish, I do the same thing with a little white vinegar, hydrogen perox. and water, and then use a couple of dry cotton ball strips to get as much of the moisture out as possible. You may have to do it 2-3 times a week, depending on whether or not she scratches her ears. Good luck.
