Pillow licking

[Nat]

We have two min schnauzers who like to lick our pillows leaving them uncomfortably wet to sleep on. They do sleep with us, so banning them from the bed is not an option. It's not separation anxiety since they typically do it in the evening when we are in the room (not on the bed) watching TV. Any idea why they are doing this?

We have three Paps and two of them do the same thing. I am guessing it has something to do with body oils or persperation, even though they seem to do it with fresh pillow cases too. Yes, it does make the pillows soggy......
