Notice how I made the ribs as discs rather than as struts. This approximates the shape of the dog’s ribcage and offers flexibility, with relative ease.

I added airplane cable for strength and to join the head to the spine to the pelvis. The cable passes in through the actual spinal cord opening, loops through two holes, which must be for blood vessels or nerves and then is ziptied to the foam spine.

The pelvis and legs are made out of wood, much as I would with a standard puppet, but without the need to have crisp movement. This puppet needs to flop.

You can see that I used a simplified pattern that mimics how muscles attach to the body.

Neat, huh?

And here I am with the completed skeleton of the dead dog. It flops well.
