This is an anthology special that suffers severely from a lack of any unifying through-line other than the fact that each segment features dogs. Most of the segments are intended to be comedic but the humor uniformly fails to land. The longest segment is a melodramatic story centered on early onset Alzheimer's which, if you're interested in a J-drama on that topic, go watch Beautiful Rain rather than this barely adequate short film. Ashida Mana does appear in the final story and has maybe three lines, including one which is meant to summarize the whole mess, but, sadly, even her usual delightful performance cannot salvage the film. Not even avid dog people will find much here of interest.
