Sign - Dog here

You can print the signs as a logo in the prusaslicer, or set the color change manually. It depends on how high the layer you are printing. Other files are modified as templates and you can try to use them and spray some board.

I downloaded pictures of dogs here: https://www.printables.com/model/132506-dog-silhouettes-meeple-for-dog-lover-board-game/files

You can freely edit and combine signs. Ben V has a choice of different breeds of dogs.
