Found a really good source including a picture of the first edition. It looks like that they were mentioned indeed in the 2nd edition to be more dog like in a sense of voice “yappin like a dog” and smelling like damp dog. Their visuals however were not really dog like. So I assume it was maybe both a mistranlation and an over interpretation of some texts from 2nd edition or just pure free choice from the author of this anime. belloflostsouls.net/…/dd-monster-spotlight-kobold…
