Presently we have a lab cross. It will protect my wife with it's life. When me and the dog are by our self, Ii's every man for himself. No body gets to stick their hand in the truck window though.
Been the same with the three previous dogs before that. A blue heeler, full blooded wolf, and Samoyed. I am not a fan of all this wolf reintroduction and think they out to be shot on sight, but ours was 1/2 arctic and 1/2 an canadian female. Best pet we ever had.
