Anyway, I called my groomer and she said not to bring them till then and to get a moustach/beard trimmer (got mine at walmart) and shave the ears my self, since I needed to get some hair off before we finished up the shots. It was very easy - and then I had to use the trimmer again, when we got the hairy plugged up poop butt syndrome
