I read it simply as a jokey ending .
On serious note ,recently when out caching , we were told by a dog owner that
some peoples habit of nicely fussing dogs that jump up at them ,as strangers ,is rewarding the dog for bad behaviour .
Big Taf had had just made a nice fuss of their 16 week puppy that had jumped up at him.
The puppy has just started training sessions with owner .
Fear it is too late to retrain Big Taf .
