The reason that Pluto is a dwarf planet rather than a planet is mainly due to it's size, specifically, the fact that it has not cleared it's orbit of enough matter.
One key piece of evidence is that Pluto does not clear its orbit of debris, a criterion used to define a planet. Additionally, Pluto is much smaller and less massive than the other planets in our solar system, more closely resembling other icy bodies in the Kuiper Belt. These factors led to its reclassification as a dwarf planet by the International Astronomical Union in 2006.
The fact that Pluto has hydrostatic equilibrium (a roughly spherical shape caused by gravitational influence) as attested to via the Hubble images. One could argue that it is a double planet with Charon which also maintains hydrostatic equilibrium and is bigger than the dwarf planet Ceres. This reviewer happens to believe that the idea of a planet completely clearing it's orbit of debris as a prerequisite to be a planet is silly and in many cases involving lagrange points is impossible.
That's a difficult question to answer, just because of how it's phrased. It is a common misconception that Pluto is no longer considered a planet. This idea is silly, though. Pluto is very obviously a planet. It is, however, considered a minor planet, rather than a major one, because it does not match defining qualifications to be a major planet. The reason it was not originally classified as a minor planet is that technology simply wasn't sharp enough to give us a good look at it. Pluto remained something of an enigma, with its highly elliptical orbit and elusive features. We just didn't know how to classify Pluto. As technology has progressed, we have been able to identify that Pluto is just too small to be considered a major planet. It is instead considered to be a dwarf planet, a category not even recognized at the time of Pluto's discovery. If we were to consider Pluto a major planet, we would also have to consider Ceres, Eris, and Makemake major planets. To synopsize your answer, no, there is not enough evidence to support the idea that Pluto is not a planet. Mainstream science doesn't consider Pluto to not be a planet. Popular culture captured Pluto's changed classification and incorporated it into mythology.
The International Astronomical Union (IAU) agreed that Pluto should be classified as a dwarf planet on August 24, 2006, during their General Assembly in Prague. This decision was based on new definitions of what constitutes a planet, which led to Pluto being reclassified from a full-fledged planet to a dwarf planet.
Pluto the planet was named after the Roman god of the underworld, not the Disney dog. The name was proposed by Venetia Burney, an 11-year-old schoolgirl from England, in 1930. Pluto the Disney dog was named after the planet, not the other way around.

Pluto, it is now a dwarf planet or planetoid.
