I have volunteered to routinely drive a blind friend to our church on Sundays. This most recent trip to church included the seeing-eye dog resisting the instruction to lay on the floor and instead was sitting tall to see out the van window. The problem with sitting tall is the awkward location of the center of gravity combined with the dog's inability to anticipate the motion of the vehicle. When I accelerated and turned the dog lost her balance. As she tipped over backwards with her front legs stiff, she fell past the middle row of seats, then fell to the left as we turned. This resulted in the dog laying on her back, wedged between the seats, with all four legs sticking straight up flailing in an attempt to right herself. My friend and I laughed so hard, it took us a while to get around to helping the poor dog.
