I've got my Yorkie for 2 wks now. He's 10 wks old-his ears are down. What exactly do you shave off? Both sides of the ears? Only the tips? Doesn't it look odd if I shave off the hair on the outside of his ears? I'm just soooo confused and don't want to mess up his looks. Once he hair is gone...well, it's gone! Any suggestions???
