I've met a few dogs out there that look exactly like Frosty. One however, was substantially taller and much goofier, and zero herding tendencies. He was pointer x something.
Frosty herds like a cattle dog herds.
Her coat is a bit funny, the white part of her is a pretty soft, shorter single coat while the darker area down her back is exactly like the typical cattle dog double coat... and her tail is very 'thick' at the base like the a cattle dog too
