How to build an obedience training set

I built a set of 3D models of all the animals in my home in 3 days.

The set of models was then fed to my dog who was instructed to walk on the treadmill to test his fitness.

The dogs accuracy on the test was the same every day, so he could learn to walk in the same way.

The only difference between the 3D model and the real thing was that the models were made of different materials and the dog was trained to walk the treadmill in the exact same manner.
