I was out in the garden over the weekend throwing balls for the dogs - have to make the most of it while the garden isn't a mudbath. Was throwing balls for the two Shepherds and Willow was at one side of the garden. She looked left, looked right, then crossed - she knows her green cross code. I suppose when you might get flattened by two charging German Shepherd you learn pretty quickly. It was so funny to watch - my smart cookie.
