Yes he's a Brussel(s?) Griffon. In Dog Fancy there was an article about the breed shorlty after the movie came out. I called a few breeders to see what they had to say about the breed because the breed was so adorable. The breed is not for me, but boy are they cute!

My next door neighbor at the time got a black one shortly after the movie came out. He was cute, but he was not quite as cute as Virdel in the movie
