Pug!!! PUUUUUUUUUG!!!
It's already my screensaver, as it happens.
And Pugs will do that, almost without prompting. My Pug responds to the word "kisses." The Girl taught her that. She doesn't kiss on the cheek, though. She goes straight for the mouth. It's great to get somebody to get their face in nice and close to say hello, and then get snogged by the curly-tailed snort machine.
