A door stopper in the form of a (outside?) running dog.

To save Material the wedge has cutouts in form of bones.

Easy to print sideways.

I added an outer Brim to ensure it sticks on the print bed as it was the first print.

Printed also a 50% smaller version - the white one in the fotos, this might work depending how wide the gap is under the door.
It shows that this model scales well.
