Boxer Pal
I think it likely is mostly dependant on the dog him/herself. My first boxer, Tiger, he was aggressive to ALL dogs, but never once even barked at another human. My second Boxer, Spike (Spikey is what we called him), he was always on edge when new people came around. Wouldnt bark but would occasionally growl and was almost ALWAYS watching any new person, on guard so to speak. Scarlet, my newest boxer, she doesnt seem to like new people around. Not aggressive, just indifferent. She loves other dogs though, but kind of avoids other people. Im not sure she would bite any burglar.
Depends on how the dog was raised and the personality it develops on its own I think.

. But I noticed in few occasions that no matter what we are doing if he heard a strange noise he will stop and sit in front of me while looking at the direction where the noise came from and he would walk besides me while im checking it out (is he trying to protect me or is he trying to tell me to protect him
