More: This is Charlie’s way of letting you know that she is ready to play frisbee. If this doesn’t work, she’ll pick up the frisbee and walk behind you tapping the back of your leg with the frisbee or she’ll carry it behind you and drop it loudly to get your attention. If that doesn’t work, she’ll flop on the floor with a big sigh/grunt indicating her utter disappointment. Her success rate in getting someone to play frisbee is quite high.
