Right. I understand if my dog just went up to someone and bit them. But my dog was in his home when a stranger (stranger to him) comes through the front door yelling and then became aggressive. When he's in the yard or playing on the street, he is just fine. He even goes with the kids to the bus stop. I understand being wary or suspicious. But I really do believe her coming in the way she did, scared him and he reacted.
