Mine aren't sulkers, certainly not enough to skip a meal. Lark took a box of tissues off an end table the other day. I found her in the living room happily destroying the box, surrounded by a cloud of ripped up tissues. I probably used some language my mother would have washed my mouth out with soap for using back in the day. Lark just looked at me as if to ask what my problem was. Did not look vaguely guilty and certainly not sulky. She just hopped up out of the mess and watched me pick everything up, looking quite happy with the thoroughness of her destruction.
Chase is a quiet boy, kind of an Eeyore thanks-for-noticing-me type, but doesn't seem especially disturbed if he gets in trouble. Barking in the yard when I've told him to stop? Not even when I go out and hustle him back into the house holding his collar. He's more like, "Oh, well, I'll be going out later anyway" and lies down on the bed closest to wherever I am sitting.
I don't remember any of our dogs being sulky. Our kids, yes, our dogs, no!
