Yeah, I'm afraid that name is most definitely made up. What you have is your garden variety mutt. They're personally my favorite. I'd love to see some pictures of your new dog, she sounds like a cutie.
I'd stay away from breeders selling these 'breeds' in the future though. If you're going to get a mutt, you might as well get one from a local shelter. You'll be helping out a pup in need and won't be supporting a backyard breeder.
