Dog duty!

When our daughter and son-in-law are both at work, someone has to let the dogs out for a quick run in the yard, so two or three days a week Bob does dog duty on his lunch break. Mabel, the sheepdog can't wait for that door to open. If she's first in, she'll be first to get a treat. At least that is her theory.  Cooper's not worried though. He'll get his treat, and he knows it, so he just sits back and smiles.
