If Muffy is more Upper East Side than down-town Meat Packing, her petiquette and manners are tantamount to her grace and style. Guarantee her “Social Register” entry when you post one of these lovely “Petiquette” cards to her friends. The Pet Set is an elegant greeting card company dedicated to promoting proper doggie “petiquette” for all occasions. All of their designs are mini works of art and are sure to impress even the most jaded play-date partner. Not to mention, they’ve just been nominated for two LOUIE International Greeting Card Association awards. A box of six 5″ x 5″ cards will set you back $21 and due to their size may require additional postage.
