No longer called Zero, Vegas LOVES to walk.  He has learned real quickly how much fun it is to see other doggies and people who give him loving!  We are now looking into obedience classes to get him more socialization.  He seems to be adjusting very well.  Loves to run around the house and loves Kongs!  You were correct in saying he is a sweetheart.  He is a very loving dog and has learned so much already.   Thanks again for your help in getting us together!
