Etiquetteer observed both of these lawn signs this morning. One is Perfectly Proper; the other is not. Etiquetteer suspects you will recognize which is which.
While signs have, unfortunately, always been necessary to guide careless dog owners, Etiquetteer does not think it necessary, or helpful, to spell out the situation so, ahem, graphically.
Indeed, one reader, Dan Hochman, suggested a new sign: "Dogs, Curb Your Owners."
