Had a pure bred as a kid, one blue eye one brown, we would build snow forts in the winter and it would sleep all day inside the snow fort. It loved the snow. It would pull me all day on my skateboard. Wonderful dog, downside it is very hard to train and loved to run, need a large yard, will wonder for miles and not come home. Someone actually stole ours off its chain in the front yard. What a cool dog.
