My Thor had ear mites last year. I too got the drops, but it did not seem to help. I suspect this was because it was such a pain in the butt to administer and I got more on the floor than in the guys ears (no one to help me). We then proceed on a course of Ivermec injectable (trade name Ivormectin), which I presume is what you mean by shots. In a nutshell we had great success. I also did a bit of research on this and got the impression that this is quite a common form of treatment for ear mites. Hope that helps. And yes it is the same stuff they give to sheep and cattle! -David, Thor, Grover, Lady Penelope and foster Snuff. [Posted in FML issue 2970]
