But then it wouldn't be a robot dog, it would just be a cyborg dog, so you'd lose the robot panache.
What you need to do is imprint your personality and brain wave patterns onto the mechanical dog's brain and then destroy your current biological body (so there wouldn't be two of you - which could be socially embaressing).
Disclaimer: Unless it was Forty Two's brain, as from his post we know his brain is already mechanical - which actually makes him a cyborg who wants to be a robot.
- though a non traditional cyborg, as traditionally a cyborg would have a human brain and a mechanical body
---- unless he's a flesh coated Terminator sent from the future in which case an argument could be made that he is a traditional model, as there have been several incarnations of this form.
Forty Two - how do you feel when you hear the name John Connor?
