Our older dog was in the other room doing this bark/howl thing he does when he either wants out or wants your food. He was doing this about every 20 seconds for a few minutes. husband and difficult child are just sitting there in front of the tv. I finally get up to do something and husband says "I tried to let him out...he won't go" Uh huh. I asked him if he wanted to go out and walked to the back door. He went right out.
