{{Short description|Genus of fishes}}

””’Inu””’ is a genus of [[goby]] in the [[subfamily]] of Oxudercidae<ref>Snyder, J.O. (1909) Descriptions of new genera and species of f ishes from Japan and the Riu Kiu Islands. Proceedings of the United States National Museum, 36(1688): 597–610.</ref>. It is distributed along the coast of [[Korea]] and [[Japan]]. <ref name=Shibukawa>{{cite journal|author=Shibukawa, N.|display-authors= et al. |year=2020|url=https://www.fujimu100.jp/app/files/uploads/2020/03/Tokai-shizenshi13-07.pdf |title=Comparative morphology, validity, and limits of the genus Inu Snyder, 1909 (Gobiiformes, Oxudercidae), with comments on the diversification of the related interstice-dwelling goby genera in Japan|journal=Bull.

Alike those in ”Luciogobius”, the species in ”Inu” dwell in [[pebble beach]] or [[rocky shore]], which provide a plenty of gravel-interstitial spaces.<ref name=Shibukawa></ref> However, it is often pointed out that species of ”Inu” avoid exposing to the air compared to ”Luciogobius”.<ref name=Shibukawa></ref>
