Alright, here is the funny thing. Her mother was a purebred Great Swiss Mountain Dog. Accidental litter, they didn't know who the dad was. There was one pup in the litter that looked exactly like the mom, a few males that looked like longhaired GSDs, and then Juniper - with her freckles everywhere. I always thought Cattle Dog, based on her looks and behavior, but none of the other puppies seemed like they had a Cattle dog dad. Maybe multiple sires for the litter?
