Sammy the Snake

Well, playing tug of war with your dog can be more enlightening than you would think.

Sammy and I were tugging away and I found that he would (on carpet no less), drop down low to the ground, and rather than dig in, he'd hang on for dear life, continue growling and tuck his front legs behind him like a high-diver going for maximum aerodynamics.

Here's some video footage of him doing this in the kitchen. Enjoy!
