What beed do you think she is?

Our pup is coming up on 12 years old this month. We adopted her from the humane society when she was about 3 months old. I've always been curious what her mix of breeds is, even though I know she's 100% good girl.

Some of her litter mates had black and white coats like a border collie. She loves the snow, is very intelligent and a little stubborn, and is great with our kids. Hates delivery drivers any anyone else that doesn't seem like they belong on the block. Others have guessed Border Collie, Newfoundland, Chow Chow because of the tail.
