treats. take on on a normal collar with LOADS if really tasty treats to grocery stores, just stand out in the parking lot and praise and reward every single time a child walks through the doors. once she is where she is not panicking on sight,the praise and reward if she so much as glances at the kids without reacting(no matter how short, so a clicker works best for this) make sure to stay outside her comfort zone, if she reacts then you are too close, so back off. you can slowly shrink her comfort zone this way.

Daisy doesnt sound near as bad as Happy was, and this method worked a miracle on Happy.
