Mo Does Calculus

In a bragging tone of voice I said to a friend, "Guess what Mo did today?!"
"Calculus??" he guessed.

Pretty much! My Mo has a very analytical mind.
A little background to the story: First, when Pat gets home before me, he lets the dogs out in the backyard. When he lets them back in, for some reason, Frankie refuses to come in. He does this instead:

Second, dinner time for the dogs is usually around 6:00-6:30 pm.

This particular day I didn't get home until 7:30 pm. When I came in, Mo and Georgie were in the house and Frankie was outside. Mo started barking all crazy-like and she ran to the back door. I figured she had to pee, so I opened up the back door. But no, as soon as I opened the door Frankie came in, but Mo ran into the kitchen. Huh? I guess she didn't have to pee after all. She ran right to her dinner spot and started up again with the crazy-like barking.

Ah...I get it. It's dinnertime! And my super smart dog knows that I feed all the dogs at once. First step: get Frankie inside. Second step: yell at me until I feed her.

Genius.
