However, dogs are also restricted in that they are not allowed to enter certain locations. We see this several times in the film, such as when Enzo is not allowed in the hospital, at the funeral and in the courtroom. Dogs also cannot speak, so they can be misunderstood and sometimes feel helpless, as shown when Enzo is unable to warn the family about Eva's (Amanda Seyfried) illness.
The art of running in the rain from Enzo's point of view enables the audience to explore and get to know human behavior together with the dog. It allows viewers to take a simpler approach, just observe and observe, without the complications that come with human observation – like over-analysis.
