Looks like a Shih Tzu to me - maybe not the ideal representation of the breed, but definitely a Shih Tzu. (The muzzle is the key for what I see.)
Keep in mind that not all dogs are going to look like an exact replica of their breed standard.
It's funny because I grew up with Lhasas, and now have Havs, and my mom has Shih Tzus. Though we've had a variety of breeds of dogs in between, we have stuck to the same general size and similar look (although they are very different in temperament and personality).
