I usually put him in his crate when I leave the house, so I did do that earlier. He was barking and barking for at least 1/2 hour. The crate is in my bed room, so I shut the door and came out on the couch. He must have sensed that I was still here.
I have been trying to get him to calm down since 1:00. Its now 3:30.
Thanks for greenie suggestion- I think its working. I usually only give him one at bedtime.
Maybe now I can relax!!!
