Piper says she agrees with Cooper: don’t lick a child’s hands; you don’t know what icky stuff they’ve touched. That said, there’s nothing wrong with burying one’s nose in their own nether regions. Or another dog’s, if you want to say “Howdy-do” while out for a walk. Or my mom’s, when she’s noshing on her BarcaLounger while watching TV, and dropping bits of hotdog bun and relish and slurps of ketchup in her crotch.
