Oh, i just wanted to add, I've seen bunjee do this one other time. a friend of mine babysat bunjee along with her yorkie. she said they played along really well while i was gone. but when i returned and was giving both yorkies some love and attention (petting one with each hand), bunjee went ballastic and started to lunge and growl and pick a fight with his friend.
i told him NO and to BE NICE. but he was still being very guarded for some reason.
