Chochi would, I believe. He hates strangers with a passion, but I do believe if one was attacking me he'd jump in. One time, my sisters friend burst through the door without knocking, catching us all unaware.( long story why the door was unlocked at the time) Chochi spring into action. He ran up to her, stood up on his hind legs, placed his front paws on her shoulders and barked in her face. I am so glad he didn't bite her. He guess he was warning her not to come closer to us. He is a chow mix, but thank god he didn't bite her! So do you believe your dog would protect you?
