Yeah that head tilt thing cracks everyone up. He's done it ever since he was a pup. In fact, it ran in several of his littermates as well. Chris Christopher's Diesel and Jason Escalara's Nitro both would cock their head a little (not to his extent), especially when they saw the marks go off good. I just whistle a little when I'm taking a pic of him, and he gives the "erra?" head tilt.
Lainee, thanks for the avatar...I need to read up on how to make it appear.
