LOL LOL It sure does look funny, doesn't it??! Our dog used to do that too. That behavior is actually left over wild canid behavior. I've noticed in my experience with wolves anyway, that if they go potty in their 'living space' or den, they will scratch at the ground and cover it up. Wolves even have a tendency to roll it up into a ball and move it to the far corner of the den!! However, the domesticated cousins...our dogs, aren't quite as effective in the whole burying process...LOL LOL
