My Chihuahua loves to lick inside my ears and I kind of like it. My wife says it drives her NUTS, but it's harmless. I looked on the Internet and it said they do that because they love you. Sometimes I think she is trying to reach my brain through that little ear canal.
They actually like to lick inside the ear because they like the taste/smell of ear wax. I know that may sound gross but animals like body secretions especially the ear. Once again, I know this sound gros but that is also why they like to chew on underpants.
oldbuddy.... I am with your wife on this one. A dog licking my ear would drive me nuts!!
Tinachelune.... when the kids were little, they lost a number of panties to the dog that way. THAT drove me nuts too!!
