Ohh!! This challenge topic is perfect for us. I can't tell you how many different looks I've caught on camera... so here are just a few I've found this morning.
The "RAWR!! If you don't get off my head RIGHT NOW...!"
The killer kitty look. I think I'd better sleep with the lights on.
The "Give me the treats!" look with lots of barking. It doesn't stop until you shove cookies in his mouth. Then it starts up once he's swallowed. Noisy boy when he wants his cookies.
