Zeus is a bit of a loner, and is very attached to me and seems to just like the rest of the humans in the family lol. He is best described as an old soul. Although the "middle child" of our three dogs he is the most calm and responsible when it comes to leaving him out around tempting objects. He has growled and nipped at our youngest son before but that was on us and our son for not heeding/recognizing warning signs. Zeus has had/needed the least amount of training, it seems like he just knows how to behave. However, Zeus is very shy and cautious of other people which I'm afraid could lead to a dangerous situation if someone were to invade his space or corner him.
