A perfect scientist starts to exchange pairs of atoms (let’s assume here that both individuals contain the same amount of atoms) so that the grandmother more and more transforms into the dog (of course there will be several weird intermediary stages).
Identity isn’t in specific atoms. The effect of swapping a carbon atom in the grandma with a carbon atom in the dog is none at all.
