I think every dog has their purpose (Job to do). I work a shift schedule, I am gone for 3 weeks then home for 3 weeks. My Shepherd knows when I am leaving, he gets depressed and starts moping around the day before. My wife tells me that as soon as I am gone he is on High Alert. He is always at her side, barks at anyone coming to the house, and roams the house at night while she sleeps. She gets kind of annoyed with it, because when I am home he is calm and melow. I told her he is doing his "JOB". As soon as I leave, he is the man of the house protecting his female. It is awesome and amazes me how they just pick up on things.
Goergous looking pup. Sounds like you have a new member of the familly. All you have to do every once in a while is pop of the shotgun and throw the duck and he will be happy.
