I suspect one of two (or both) things happen when you call your pup.
1) "Pumpkin!" Pup looks at you, but doesn't move. It waits. It knows one of two things are going to happen. You will either be frustrated and use a squeaky whinny voice (GAME ON!!!) and chase down your pup!! WHOO HOO!!! Pup LOVES that game!!!
2) "Pumpkin!" Pup looks at you, but doesn't move. It waits. Now you're ticked. You're tired. It's past bed time and the dang dog won't move!! ARGH!!!! What comes out of your mouth next would scare the smirk off a scarecrow. Puppy says, "Oh hec no!" and runs for cover.
Am I close?
