I had a good laugh yesterday with my friend S., when he told about his dog (a Rhodesian Ridgeback,
one of my favourite dogs!). This dog is a young one and he has an older dog as well. His family has taught the older dog that if he needs to go outside for a pee, the dog rings a bell and they let him in the garden. The younger dog picked up the bell ringing idea quickly, but... only for going outside. So the dog rings the bell, my friend lets him out. The dog stretches a bit, walks around the garden, sniffs here and there, but no pee. Then he wants to get in. And later he rings the bell again and my friend lets him out because the dog didn't do anything the first time. But no, again the dog just needs to get a bit of fresh air!
So the dog has learned one part (ringing the bell to go outside), but doesn't make the connection with the real intention of his owner (going outside only when he needs to go for a pee). I can imagine this could happen in the human world as well. If a person learns the skill but doesn't really know or understand the reason behind it, when he or she then teaches the skill to a novice the emphasis will be on the surface part and not the full intention. Teaching means not only getting into the how, but the why as well.
Of course this won't work for the dog, explaining the why of an action. I'm not a dog training expert, so I leave any recommendation to others. Meanwhile, the dog is giving my friend some exercise!
