I think my dog has an eating disorder

This is what I came home to the other night...Let me explain something, this jar of peanut butter was 1) FULL 2)Ontop of the kitchen table 3) Closed. This may explain my surprise when I came home to this scene.....

I had no idea she was a binge eater!!! Here is what it looked like at close range. I mean seriously how many calories is that??
