In 1959, Soviet scientist Vladimir Demikhov actually managed to create a two-headed dog. After 23 tries that left his canine subjects dead in short order, he was finally able to achieve a small measure of success.
He grafted one head onto the other’s body, sewed their circulatory systems together, and connected their vertebrae with plastic strings. After the procedure was completed, both heads could hear, see, smell, and swallow.
Sadly, his methods were still relatively crude and the dog only lived four days before dying. While his research was a pioneering foray into head transplantation, experts debate the ethics of such procedures to this day.
