Happy dog in the waiting room.

Moose is the happiest dog. Even when shaking with tremors, unable to eat, unwilling to move and in unknown pain, he smiles. Even when laying on the tiled floor of the puppy ER, he smiles. He makes himself get off the floor to give a friendly welcome to visitors who sat a few seats away. Then he smiles. Awaiting tests, x-rays, ultrasounds, poking and prodding in the room, he smiles. 

There's nothing Moose doesn't do without happiness.
