A five-year-old Affenpinscher is top pooch at the 137th Westminster Kennel Club Dog Show.

Tuesday night at Madison Square Garden, Banana Joe became the first of his breed to win the "Best of Show" category. He beat out six other contenders for top honor. Handler Ernesto Lara says Joe doesn't know his size or know that he has a pushed-in face, rather he just "thinks he's Mr. America." Plans are to retire him in the Netherlands, where he was born.
