Hi! My puppy Pax is really great in most regards. He comes to work with my every day and is friendly to all my coworkers. I work in the shipping/receiving dept. of the story, so sometimes if Pax falls asleep in the middle of the room, he needs to be moved over for the cart with boxes coming through. When I wake him, he simply gets up and moves over to his bed. However, my coworkers and I have noticed that when they wake him up, he growls. On a couple of occasions, he's even nipped at them. He's only 4.5 months old, so I want to fix this before it develops into something more. I was thinking maybe having them wake him with a treat so that he gets something positive for having to move. Any thoughts?
