Poor Arwen. She got seconded into posing on the dock. Her Preciousssss was pried from her jaws and used as bait to capture her attention. 

Sit, Arwen.

Stay, Arwen.

Good Arwen.

Soleil (who was supposed to be on the dock with Arwen, but who had blown me off spectacularly) goes in for the kill.

It's too much for the little Labrador's brain to handle.

Gauntlet. Thrown.

Game on.
