Silver is going to be a protective girl. I had just finished training with her outside and was walking toward the porch to get her the rest of her dinner when my son ambushed us by jumping off the roof of the house. He landed about 15 feet away in a poof of snow. She reacted by bouncing towards him, hackles up, barking. When she realized I wasn't accompanying her and how big 'it' was, she turned and came back a couple of feet towards me, but her tail was still 3/4 up & she was watching him. And then my son laughed and she realized who it was and went running back over to him. Good pup. :)
Wish I'd been able to snap a picture. Photo is of Silver in the house.
