How is the puppy doing now? He should be in the adult stage by 2015. However, my comments are on this particular video. What your puppy is doing may look funny and cute at the moment, but it kind of shows your dog is losing and opportunity to learn an important lesson about ownership. You have an opportunity to demonstrate to the dog proper "rules, boundaries, and limitations." The rule should be that he has his own toys but that if it's a human's possession then it's off limits to take. Also he wouldn't be doing that so much if you gave him a lot of exercise and basic obedience training. I hope he's doing much better now.
