is it normal to single out yorkies to hate?

A friend of mine looks forward to meeting his gf, so he can show her little Yorkie who's boss. So when his gf isn't watching, he does the following: holds the neck of the Yorkie down forcefully and pulls at the hairs on the butt end whilst gripping hard and pinching the area behind the neck region. He wraps up fine black pepper in a piece of foil and secretly dusts it over the Yorkies nostril and face. He holds the Yorkie head high then drops it on the floor just in time to deliver a short drop kick to the ribs, but not hard enough to break bones, that would just send the yorkie to the vet and, he wants to enjoy a slow torture instead of a hard kill. Next he puts the yorkie in the tumble dryer on cool setting so the yorkie can spin inside the dryer to the tune of its own whimpering whilst it pisses itself wet in the dryer. At times the yorkie is placed in a small plastic shopping bag, and the bag is hung up on a coat hanger or somewhere for half an hour. His favorite thing to do is place the yorkie in a toilet then close the toilet lid on it for an hour at least. But the thing he loves to do the most is tie atomic loud firecrackers to its tail till the yorkie goes off its rockers. I think I will show him this post because I see now that its normal and ok to do what he is doing, absolutely nothing wrong with it at all.
