Weirdly enough, she reminds me of my dad's four month old chow mix puppy. I wasn't too certain until I saw the picture of her siblings and saw the longer haired puppy. We believe Dooley, my dad's puppy, is a chow and retriever cross.
If I had some recent pictures I'd post them, but Dooley looks eerily similar to the longer haired puppy in the group picture. It looks like the puppy has the same sort of coat as well: darker tail tip, with what looks sort of like sabling on the rest of his/her coat. The tail looks spitzy as well, like Dooley's. Dooley's fur is relatively coarse, although the fur on his face is unbelievably soft.
Adorable puppy, nonetheless!
