First post in a long time.
Just to update, Duke is still the devil with brown eyes.  Look behind one eye and you will find Satan. Look  behind the other and you will see the Devil.Several weeks ago he would not come so we could go home. He simply does not understand the command. I will never tell how long I waited for him to decide to get in the car. Of late, he has been doing the same thing. Usually someone else grabs his collar becomes he iis interested in everyone but me.
