But the world would not be the same. Let me give you a somewhat silly example. In the TV series UFO, a moon to earth shuttle crashed. Sabotage was suspected. A pilot said he'd fly the same route to see if anything was there to sabotage a flight. Well, that's just impossible. The earth is in a different position in relation the the sun, the moon is in a different spot in relation to both the earth and sun, and the entire solar system has moved in relation to the galaxy and the universe. To paraphrase a saying, it's never the same river twice. The entire environment the clone would be in would be drastically different than the one the original was in, so it'd really be impossible to get a truly identical experience. And a dog's senses are different than a human's. What you would never notice as a significant change the dog probably would -- and that too would have an effect.
