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.
In Germanic folklore, kobolds just look like small people that are often also depicted as being green and having large ears. They are spirits of the home and sometimes benevolent and sometimes mischievous.
also the spirits of mines that are sometimes benevolent and sometimes malevolent
cobalt is named after them because it was a toxic ore seen as a contaminant that caused injury and death to miners
