Chief is super sweet too! He loves other dogs and people! He just goes I into protection dog when he's not sure about something. I forgot about this, a few days ago my husband was on the couch watching a game, Chief was laying next to me sleeping (I was on the floor by the couch) and my husband yelled and threw his hands up at the game. Chief immidelty stood up, stood over me and barked at my husband. I want him to be protective but at the same time I'm thinking "your only 5 months old... this protectiveness may grow stronger and stronger..." Is this bad so young?!
