Your dog loves the snow—and it looks like evolution at play.
You learn from a DNA test that your dog is a mix of several breeds, but her most abundant ancestry appears to be Great Pyrenees. This knowledge biases you, of course, but you can’t help but notice her conspicuous qualities: a need to herd and protect the members of your family. A desire to run (for very short distances). And a particularly alpine love for rolling in snow.
