Hi, thanks for using Petco Pet Education Center, formerly Petcoach! In my experience ears mites are more of a puppy and kitten disease. In dogs Stanleys age the number one reason or scratching the ears is an ear infection-either yeast or bacteria. Your Vet can check the ear discharge under the microscope to see if there is an overgrowth and prescribe an ear wash and drops. If there truly is no ear infection then allergies are very likely. Even ear infections can start due to allergies. Food allergies are some what easy to rule out. You can try a diet that doesn't contain chicken, something like venison, duck or fish. All treats would have to contain the new protein, so no people food. And you would have to give the diet 2-3 months. Good luck!

    Poor Maddie, ear problems can be common in dogs and it is not fun to watch them scratching and being uncomfortable. Unfortunately ear mites can only be diagnosed by visualizing the mites. Typically this is accomplished by using an instrument to look down into the ear canal and then also obtaining a sample of any discharge to see if there are mites present. Obtaining a sample also allows for assessment of things like yeast and bacteria which commonly cause itchy ears. This will also allow your vet to pick the right medication to get her feeling better as soon as possible. If chronic ear infections become an issue underlying allergies may be a cause. Your regular veterinarian or a dermatologist would be helpful in diagnosing this and providing treatment. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
