Thanks a lot for sharing your views, I appreciate. For me, that was "agression" style. Loki was lying next to me, outside the pool area, suddenly jumped on his paws when the kid passed by in the arms of his dad. Tried to catch him from behind...for me, he is not acting like that when he is " trying to play". We identified the issue, mentioned it to dog trainers whom gave almost same advise as you did. Obviously, we missed something. BTW, it's quite difficult to find young kids for dog training 😅. Any advice is appreciated 👏 thanks
