A sad episode! Maybe even more so since the other dog seems so very content with life, with fetching sticks while his owner obliviously speaks on the cell, gives a strange impression of a happy life that seems to serve no purpose, and though the lost puppy reminisces in his lonesome lair, the other life isn't given the appeal it seems to need to make pinpoint his purpose: what he wants, regardless of what he remembers. Well I'm probably overthinking this thing, was nicely animated though, simple; atmospheric!
