LOL !! From the picture - that's about the age Cheri was when mine started making out - now they're Makeout QUEENS
They kiss each other everywhere we go - people can't believe how much they make out - they had my DIL totally melting a few weeks ago - she'd never seen dogs kiss like like that
Then you can teach them little phrases - Like - "Give smoochies"....or "MOVIE Kisses" and they'll wiggle their little heads lol
