lol my dogs bark like crazy and get VERY protective if they see someone on our property, when they know who it is they calm down however iff not watch out. shadow has held intruders in one spot before, oh no, she wont attack them, she just growls, snarles, and circles the intuder holding then in place until you call her off. now she is very good with people she trusts, one creepy person was staring and hanging around the car while I was alone(exept for shadow) in it, I locked the doors and shadow cimbed on my lap, and litterally gaurded me, she would show her teeth at the guy, and bark if he got to close. while in general if people are walking around she could not care less. she is an exellent judge of character. recently since she is staying with my friend, the alarm went off and my freinds cousin was called he walked in the house, shadow has never seen him before, she she did not even bark. now if she had not trusted him, he would not have gotten very far in the house lol
