Later during my visit to North America, someone told me where that dog poo had probably come from. A sharp businessman was making a fortune potty training pet dogs whose owners lived in city apartments.
Anyone who has had a new puppy in their house knows how troublesome it is to stop them doing their business on your expensive carpet. This businessman guaranteed to train every dog within three days to poo only outside. He used positive reinforcement.
He or his employee would take the pooch onto the street, to a tree or a small garden, and wait until the dog pood or peed. Then he would jump up and down shouting with glee, punching the air, dancing a jig, and singing a happy song. Sometimes the trainer would even do cartwheels. He would go way over the top in exuberant celebrations and extremes of ecstasy over the dog’s excretions. It worked! That dog sensed that it had made someone very, very happy. Within three days, the dog would only poo outside. Such is the power of positive reinforcement, even on animals.
However, the dog trainer later got into big trouble. Some of his clients would be watching a game on TV, sitting quietly on the sofa with their dog. Then their team would score a spectacular touchdown or goal, and they would jump up off the sofa in glee, punch the air, dance a jig, and sing a happy song! And guess what the dog did?
