I agree with your review. And I loved all the detail in the animation and the dogs. Just incredible and done with great humor.
But I couldn't help but see a political parallel in terms of the current US administration's antagonism towards immigrants. Mayor Kobayashi uses 'Fake News' to convince everyone that all the dogs must be banished. Hmmmm. But I only let that seep in to my enjoyment of the movie momentarily. It's a fun film and the artistry is top notch.
