Last night I took Zack round the large park near where I live for his walk. The only trouble is there were lots of rollerbladers and skateboarders about. Zack has been really good for months now with the rollerbladers but after about 10 whizzing by last night Zack had had enough. The unlucky 11th person got a full fledged Zack attack!!!! He was zoned in to kill that wheeled beast. Now the rollerblader knows how it feels to get the shock of your life from behind without warning.
