Toffee pouts too! When I pull my bags out to leave, I swear she frowns. It's all for show, because according to my parents, she's playing with her squeaky soccer ball approximately 3 seconds after I pull out of the driveway, but she sure makes me feel guilty!
She also lets out big sighs if she is disgusted with you for some reason (like making her move when she doesn't want to).
Last weekend at the horse show, we met a little boxer puppy (SO cute!!) that was 3.5 months old. She went over to her and sniffed and then turned around and sat with her back to the pup, LOL! Whenever I went to pet little Lexie, Tof was right there, though. It was funny to see--she consistently reacted that way to the puppy over the weekend.
