If you could add any breed, what would it be?

What Breed Would You Add To Nintendogs?

I would like to ask everyone here what breed they would add to Nintendogs or Nintendogs + Cats if they could somehow. I believe I might add a Border Collie even though there is already a Shetland Sheepdog, haha. I bet there are a lot of breeds that could have been added but only very popular ones were since they could only squeeze a few in. Too many could have caused the game to mess up or lag a lot or it might have just taken a lot of programming time. Anyway, which one would you add if Nintendo allowed you to choose a new breed to add?
