For some reason, this pup seems like something Fiery Gatoh would do. They always do nice, simple but unique designs that aren't anything extremely fancy and there's never really any lineart edits. It seems like they really like three tailed dogs, too, since 3 of their staff dogs have been 3 tailed, so it could be this one:

But the three tailed pup lineart hasn't existed for long and three tailed adults always grew from one-tailed pups in the past.

This one could work, too, I guess, since it's so simple at this stage.
At this point, these are the only three that really seem to fit their style from what I see. And for some reason that first one just says Fiery Gatoh to me. xD I can also see the 2nd two changing quite a bit later on because of the words around them, so maybe that's why the first one makes me think Fiery Gatoh so much. owo
