Indeed, but then wouldn't an animal having a soul not also be able to choose the life that it's entering into much the way a human would? Would an animal not also be choosing one of challenge at times, while at other times choose one of comparable luxury, as our dogs had chosen with us this time around?

Or is this something only we humans can do? Is an animal simply a victim of random occurrence? Is there a difference in the depth and quality of each? You open more questions than you resolve with this observation....
