She Heard Her Name
Barley, a dog, sploots on a carpet with only her hindquarters in the frame of this animated GIF. After a pause, her tail begins wagging enthusiastically.
Barley is very tuned into how much attention is being paid to her, and she’ll display some provisional excitement if she’s given an encouraging (but not definitive) clue that fun times are ahead. Certain words mean it’s time to hit the gas (“walk”,”eat”, and “snack” are all turbo boosters), but if she hears her name, it’s probably a pretty good sign and she’ll get the engine turning over in case there’s more good news.
