Can you identify this breed of dog?  A PTB writes:

My girlfriend came across the image from your article about Nintendogs and absolutely must have a puppy like that.  Unfortunately, we don't know what breed of dog it is. Do you happen to know the breed of the white puppy on your article or the source of the photograph so we can figure it out?

I know nothing about dog breeds, so I'm turning this one over to you all out there.  The image is one of the promotional photos released to the press by Nintendo for the 2005's Nintendogs for the Nintendo DS.  Do you recognize this breed?  Leave a helpful comment if you do.
