I'd go with Border Collie/Lab. I've always thought she looked like a Swiss Mountain Dog. The insurance company is one of the reasons, years ago, we didn't get a GSD, as we wanted. We had a Shepherd/Collie when we moved here and the insurnace company hasn't asked since. I told them he was a Collie mix. But look what we ended up with! Lacey, maybe Shepherd/Rottie?, Layla, Shepherd/Lab, looks more like Shepherd/Wolf. At least Jake is smaller.
