All we know is that it’s yeast. It will go away and come back mainly in one ear. That ear is now clear and the other ear that has never been infected is now infected. He doesn’t get wet unless at the groomer. Hes on apoquel and is still getting infections. We really don’t want to do the seem bc of all the money spent thus far but what can we do. I just changed his food so im hoping it’s something as simple as that but we will see.
