The big directorial choice Anderson made was to linguistically divide the dogs from the humans. The humans speak Japanese and are not subtitled. We, like the dogs, do not understand them. We rely on interpreters to give translation sometimes. Sometimes, we are just left in the dark. The dogs speak English, or rather their barks are voice-translated in real-time. There is a language disclaimer right in the beginning. I understand the separation he tries to make, putting the audience firmly in the dog world. That being said, I was not crazy about the bilingual foreign exchange student saving the day. A student movement rightfully has its place in the movie, but it doesn't have to be led by a white student. She serves as a convenient means of translation, but Anderson is clever enough to have figured that out. They could've diagrammed their plans, for example.
