when i got buster he was a free to good home and was scared of various things like if i rustled a plastic carrybag near him he would shithimself and run off i taught him that good things come out of carry bags like his dinner lol i put his dinner bowl in the carry bag and he learned to deal with it
as for him protecting his territory thats his own doing when we moved to this new house he started getting all territorial so i just taught him how to deal with tresspasers if the situation ever arose
my dog always alerts me to people outside the house and if anyone ever tried to get in they would have to deal with me befour i let my dog onto them
trust me i can be as scary as my dog if i felt the need to
i love my dog to bits and if i felt like me or the dog couldent deal with the situation i would let them take the weed my dog is more important to me than any of that
cheers all
