Remember when I said that a character's personality tends to become set the moment other characters refer to it? This is what I mean. Charlie Brown's exaggerated reaction could be taken as cartoonish hyperbole right up until Violet and Patty remark upon it. That proves that his hysterics are intended to be hysterical, and the relief the reader feels at having any first reaction to CB's weird behavior as weird justified lends extra comedic punch to the strip.
Roasted Peanuts: dedicated to over-analyzing each strip to the point where all humor is lost!
(P.S., Again I feel compelled to remind you: don't give your own dogs chocolate creams, or indeed chocolate anything. Chocolate is toxic for dogs.)
