Yeah, yeah, yo queiro. This is Cindy, surrounded by a forest of her cups and trophies. The expression is priceless - on a human, it would indicate utter stupidity, but on this dog it looks bemused and ingratiating.
Dogs smile, but its a natural posture for their mouth when theyre relaxed. Some theorize that theyve learned to mimic the human expression, and if thats the case, this dog has learned to copy the smile of a smart, homely teenager who thinks that girl might like him. Uncertain, eager, happy to please.
