What in the world is Leo ???

I'm a sucker for technology, so when my curiosity gets the better of me (this is the 4th time) I send off a cheek cell sample for a doggy DNA test. Leo definitely has me baffled....the only idea I had was Teacup Tibetan Mastiff, but I don't think that they exist (ok, I know they don't exist). Below you can see the similarity between Leo (50lbs) and a Tibetan Mastiff (150lbs).
Any guesses? Results are due in 2 weeks.
