I went looking for some custom dog meeples for David Short's Dog Lover game https://boardgamegeek.com/boardgame/344839/dog-lover but I couldn't find any. So I took silhouettes of various dog breeds, vectorized, and extruded them. These all are sized approximately for the game, but can be scaled. They are typically about 50-55mm on the long side and all are 9mm thick. Printing in different colors allows for you to have a chocolate lab and a golden lab, for example.
These could also be used as children's toys, as they are sturdy and solid.
There are also mk3-sized plates by color, should you want to print a bunch of a certain color.
Note there is one dog, Daisy, who has an additional layer to print in two colors. This is the game designer's dog, and I took the art from the game to make this print for him. I've included it if you want to print as well.
