I think Mr. N looks mostly Yorkie and that’s the most common guess from people. Some people guess other small fluffy dog breeds (Shih Tzu, Lhasa Apso, Silky Terrier) which is understandable. And even other dog bloggers seem to confuse Mr. N (Yorkie/Maltese) with Oz (Cairn Terrier) periodically.
There have been some totally off-the-wall guesses though. I think my favorite is the guy who asked if Mr. N is a Corgi.
This is a Corgi:
This is a purebred(?) Yorkie in a puppy cut:
