This is a good question. It is probably best to start with a definition of what a dwarf planet is and then discuss whether Pluto is a dwarf planet.

According to the International Astronomical Union (IAU), dwarf plants are a spherical body that orbits the sun, which has a large enough mass to have its own gravitational pull, but not  large enough gravitational of a pull that it clears its region of planetesimals.
