A Pooch-oop

What is it with dogs when they poop? Both front legs stiffen up straight, back arched, hips dropped, and a silent "hooo-raaaaaah" followed by a thump that is quiet enough so that only the pooches can hear. Some will try to take back that small piece of pride that was taken during their subdued stance of shame by kicking some grass or dust on top of the fresh pile as if it were an arguing coach kicking dirt on the shoes of an umpire. Others will turn around and take a bite out of it. I guess both ways can be an ancient, in your face, "I WIN" to the food chain that still has yet to be evolutionized with bagged food.
