Ah, I figured your room mate may have had a role in that method. It’s okay though. I started out by learning that old-fashioned way of spanking/popping/etc. luckily, my very first dog was rather forgiving, and now I have a strong bond w him.
I love positive reinforcement, but I also execute sharp corrections when needed, and always try to have a job for my boys.
I agree with Tabitha, boredom or other lack of motivation may play a part in it (I doubt it’s nutrition, as you take good care of his diet!). Try to figure out a mind-stimulating activity (agility, obedience work, Treiball, flyball, or make up a game with a goal) and set aside at least 10m a day to work on it. Shasta loves his agility, and Loki benefits greatly from distraction-training via obedience work.
