Niels Matthijs (Onderhond)’s review published on Letterboxd:
If you want something light-hearted, fun, and visually exuberant, Citizen Dog is your film. It's a lovely little comedy with a lot of heart, warmth, and plenty of interesting and original ideas. It might be a bit random and episodic at times, but if you can look past that you might be in for a very pleasant surprise. And if all else fails, you can still amuse yourself by trying to comprehend how Sasanatieng came up with all these crazy color combinations. Warmly recommended.
