A quick tip in dominance training
A very important part of puppy training is to assert your dominance as the pack leader. There are a few common exercises and one particular one I like to follow is to grasp Loki by the neck with a firm hand (much like a jaw), hold him down on his back and then relax him by massaging his underside. This is quite effective to teach him how to submit to the pack leader (you). However, there are times when he does get fiesty and fight back by thrashing back and forth. A good way to overcome this antic is to allow him to "flip" and quickly use his momentum to pin him to the other side. Usually he'll resist a few times, but he soon realizes that the only thing his efforts have accomplished is to switch which side is pinned down and thus he submits.
