I was reading about Dungeon Meshi and Kuro, the “kobold”.
Kobolds are usually depicted as canine humanoids in Japanese media compared to the more reptilian humanoids that kobolds are depicted as in western media[4] such as Dungeons and Dragons. The reason for this is credited as either a mistranslation of the first Dungeons and Dragons Monster Manual[5] or because of the lack of reference art in said Monster Manual, but a picture of a jackalwere being present on the opposite page[6], which was then used as reference art for the anime, The Record of the Lodoss War. That anime is credited for solidifying the trope of canine kobolds in Japanese media.

And the supporting youtube video https://m.youtube.com/shorts/rUntTZ6spOc
Bonus fact: piglike orcs.
https://ja.wikipedia.org/wiki/コボルト seems to have a bit of a different approach stating that D&D 3rd ed. changed them to be more reptilian. https://en.wikipedia.org/wiki/Kobold actually seems to corroborate this. I played D&D since the end of the 1st ed. days and I think of them as kinda dog-like heads that were also scaly. I have a 2nd ed. Monstrous Manual, but it’s on the other side of the world at the moment so I can’t check.

I’m not buying the OP here.
My only real experience with them is from Pool of Radiance, the first “gold box” CRPG. They were pretty dog-like in that.
