I'd say Shiba Inu mix! Many people were convinced my little Tobi was what people think is a "Mini Siberian Husky" [which don't exist] also known to the educated as the Alaskan Klee Kai! (He's in my avatar)
He's really a Shiba Pomeranian cross.
Maybe He's a Shiba mixed with something like a JRT, or some other sort of terrier, maybe even an Italian Greyhound or a Whippet considering the shape of his muzzle...
And Shibas aren't rare, they're just not as common as a Labrador.
