But, it's a new issue, and that coupled with the fact if you stick something in the ear and the ear drum is not intact you can permanently damage the inner ear, the vet needs to make the diagnosis and check the inner ear to make sure the ear drum is there before putting anything into it.
Our vet told us ages ago, if we get a dog that has a gunky ear, to make sure the eardrum was intact first - if we couldn't ascertain that and they were closed at the time, we were only to use saline solution to clean the ear, because it's one of the few things that won't damage the inner ear permanently.
-so if one of mine were to start it would go to the vet. I think this is Kira's first one....
Libby, after a lifetime of good ears, recently developed itching, scratching and holding her ear wonky, indicating pain at the least or pain/itching.
I brought her right in, now that we have the medication, if she starts acting like that again, we administer the medication right away and see if it clears in a few days.
Going to the vet is never a bad idea
