What kind of dog is suitable for protecting its owner and looks good?

Samoyed and huskies are not suitable. Their obedience to their masters is poor, their physical strength is too strong and their destructive power is too great. If you like older dogs, you can choose sheepdog or Du Binquan (the dog that needs ear surgery, which is the kind of zombie in Resident Evil), but black shellfish should be the best choice.
