What would you do?

i have 3 female dogs. 2 of which have/had this. the temporary solution was those drops, it works, for one of my dogs it worked very well. consult with your vet about a possible infection or parasite, both are possible, both should not be much of a problem if treated timely. i really hope my two cents helps you, and im sorry for your dog's discomfort, i hate when my pets aren't at their best :(

Awww, your poor dog. There are different types of earmites, and one the vet would have to take a scraping of her ear to find. They are called scabies and if he didn't take a sample, he wouldn't know if they were there or not. It causes intense itching and needs to be treated quickly, as these mites lay eggs, and then they re-hatch. The medicine will kill the mites that are seen through a microscope but not the eggs, this is why it takes so long to clear up, and the medicine needs to be put in their ears for quite some time. Sometimes they will dip the dogs in a solution for a quick kill. It's miserable.

Has the vet checked your dog for allergies? Allergies can make dogs' ears itchy. The problem is that dogs can be allergic to many of the same things humans are and it can be expensive to nail it down to a particular substance (there may be more than one, also). Try switching her to a low-allergy dog food and see if that helps. If she does have allergies, here is a link that will help you: http://www.mahalo.com/how-to-care-for-a-dog-with-allergies
