My Cavalier, Cooper LOVES licking feet. In the winter when I have slippers on he knows how to push them off with his nose so he can get to my feet.
Am I the only one who thinks this actually feels good????!!!!

It's like a little mini foot massage!
Both Cavaliers are also PRO ear cleaners...they clean each others' ears, the other dogs' ears, the cat's ears when we had a cat. Thankfully they don't clean human ears. Bleeecchhh!
