Mr Pavlovian Conditioning himself, Ivan Pavlov, was provably very cruel to dogs in his experiments, see the photo (not for the squeamish) even putting a tube in to the dog's stomachs to measure their gastric juices. How truely barbaric and sickening and what a waste of time. Everyone knows when its dinner time, they don't need Pavlov to tell them with his vile, waste of time, stating the obvious, experiments.
