How does that work for a rat? Sounds interesting.

I don't know how it works for rats, but I assume it is like with dogs. If you have already a trained dog, you make the same exercises with the trained and the untrained dog, so the untrained dog can just watch what the trained dog does and imitate it.

That's not how you would typically train a working dog.
