DO run as fast as you can to the gate, skipping on three legs when required.
DO breathe hard from all the running; apparently it makes you sound happier.
DO wag your tail until it is a supersonic blur: numbness is a good sign you are doing it right.
DO stretch your mouth wide and hang your tongue out: humans like that and should respond likewise, but without the tongue.
DO dance on your back legs for each member of the family: this scores bonus points if they’re holding food.
HOWEVER, despite your best intentions, DO NOT roll in a fresh puddle of warm horse urine; humans apparently don’t understand the gesture, and unfortunately don’t appreciate it either.
