I posted a picture of Zoey when we first got her, now she's just over a year old. She loves the snow and loves chasing discs. So put them both together, along with some frozen fingers, and you get a pic like this.
Here she is chasing one down thrown by our son as I sit in the neighbors yard to get the picture. This is from about 60 feet or so out. Told our son to aim at me and he pretty much put it right over my head, which brought Zoey right to me running full-on.
