When I was in 3rd grade, the neighbor kid next door (5th grade) had a great dane and a cat. One time when ringing his doorbell, the door opened, the cat ran out with the great dane hot on his tail. The cat stopped and took a quick emergency poop (fear reaction?) and continued fleeing the great dane. The great dane, pursuing at high speed, came to a sudden stop, sniffed the poop, ate it, and continued his high speed pursuit. I lost a lot of respect for dogs that day.
