Seen via english sub genre: this is scifi but more art/music video. Anime shows are very powerful. Although i personally watch happy films. Sadly, this one is a sad one. A mutt's travel through life with no friends. It really was heart breaking. The beginning and ending is never really explained. I will assume that for what ever reason human life could not function in that town and had to go. Animals like the dog and birds could so stayed. But that ending... was the robot their to help? was he or she there to monitor? i think the idea of a bomb threat was what the directorhad in mind for this.
