Gonzo does the barking and initiating play thing when he hasn't been exercised enough. If this bothers you, ignore the behavior and wait until it stops, THEN take her out to play ball/frisbee/tug/etc. I just worry about zealously knocking over your little girl, it happens, and that is a clear sign that she needs more stimulation, play, and full-out exercise. Make sure you provide that for her and let her know that it's good to be playful where it's appropriate (outside). One thing for sure, you should be the one initiating play and saying when it ends, not Zoe.
