We had a dusting of snow overnight and the lane was covered with black ice which confused Luna with her slipping and sliding, fortunately I didn't.    She was trying to eat the ice and the frozen grass is a new tasting experience for her. 
I bought her a retractable lead and we've been using it for a couple of days.   She loves the little bit of freedom it gives her and on part of the walk this morning she choose to walk on the field headland whilst I walked on the lane.   I liked this picture of her towering above me
