I can't progress from the story. The mission with the discovered dog. It won't let me interact or do something about it. I think it bugged out or something. Is there any way to reset or restart the mission?

Are you talking about Transformice Adventures or Dead Maze?

If it's Dead Maze: there is actually a forum for it here: https://atelier801.com/deadmaze
Lots of people have already posted there about problems with the dog, and the general advice seems to be to complete the quests without it.

A description/walkthrough of the quests can be found on the Dead Maze Wiki: https://deadmaze.fandom.com/wiki/Quest
