Mine do the same, but what I have especially noticed is that when the dogs play with each other, with Baxter especially there is a lot of muzzle in mouth going on. I think it has a lot to do with showing submission. When Baby puts her head in Baxter's mouth when they are nuzzling she seems to be submitting to him. It's almost an extreme showing of trust. So, I think in addition to affection it is a sign of "I'm all yours!".
