I enjoy figuring out mixes, too. My best guess on Jenny is so




Grey and Grey___________ lab and whippet

Momma Grey_________Papa mix

Jenny & friends

.

I see lab whippet and grey in her

If I were to put BC in there, it would be mixed with the whippet, probably. I don't see any BC in her, though. . HOWEVER, I must add, I've never seen any BC grey/whippet mixes, so with mixes anythings possible I guess!
