Because it was way too small to be a real planet.

Some may be annoyed by my nit-picking. It is not that Pluto was singled out and redefined as a dwarf planet (and by the way it is not Pluto's size that is at issue). A definition of planet was decided upon, and according to the definition Pluto does not meet criteria to be considered a major planet. Pluto has not cleared its neighborhood (the Kuiper Belt) of debris. It may well be that Pluto's then-disputed place among the major planets fueled the need for a definition, but the definition was needed and the current one seems reasonable to most.
