Ever trained a Chow or Akita? Somewhere in between.
They do care about their family more than these breeds, but as far as obed. and listening when something happens, good luck.
They are quite a bit of work to raise in an urban setting; socializing btoh human and dog, training with distraction, environmental, etc...
If you blow off the formative year training and imprinting, you will have a beast on your hands.
