Arlington is a fairly rural area -where trucks are used in FS. Dogs can be a recurring issue as there are a lot of more rural properties with big dogs. It is also filled with conservatives, gun owners and good schools.
My daughter lives there not far from a KH (which is in a largely industrial area of town.) But she lives in town area. Not once was she visited by JWs and she works 2nd shift, so there is a lot of opportunity to catch her. Her neighborhood is safe for old ladies and small children.I
Dogs are greatly dependent on their humans for behavior. My mom rescues small dogs that are not people friendly and tries to love them into being social creatures. It's not terribly successful in spite of love, care and dog whisperers. Can you imagine trying to remake the personality of a more dangerous breed? Too much moral and legal liability there!
