However, dogs are also limited in that they’re not allowed to go into certain places. We see this several times in the movie, like when Enzo isn’t permitted at the hospital, at the funeral, and in the courtroom. Dogs also can’t speak, so they can be misunderstood and sometimes feel helpless, as shown when Enzo can’t warn the family about Eve (Amanda Seyfried)’s illness.
The Art of Racing in the Rain taking the point-of-view of Enzo allows the audience to explore and learn about human behavior along with the dog. It allows the viewers to take a more simplistic approach, to just observe and watch, without the complications that come with human observation--like overanalyzing.
