A dog who has a perfect understanding of acting for some reason (even while he's still a dog) turns into a human when he desperately tries to get to his injured owner, only to find out that he's already dead.

So since he has nowhere to return to (especially since nobody would understand that he used to be the dog), he acts like an amnesiac from a drama in order to get taken in, and starts a new life.

A story written from the perspective of a dog is something different, but... more>> not exactly entirely convincing.

Spoiler

In particular it's strange to me how he doesn't do anything regarding revenge for a year, but then all of a sudden every action he takes is purely oriented at taking revenge and nothing else.

(Not a significant spoiler since it's technically still part of the exposition, but I hid it just in case)

The story has some potential, especially with the dog-identity humour, but it also has some flaws. <<less
