In 1954 Vladimir Demikhov shocked the world by unveiling a surgically created monstrosity: A two-headed dog. He created the creature in a lab on the outskirts of Moscow by grafting the head, shoulders, and front legs of a puppy onto the neck of a mature German shepherd.
Demikhov paraded the dog before reporters from around the world. Journalists gasped as both heads simultaneously lapped at bowls ofmilk, and then cringed as the milk from the puppy's head dribbled out the unconnected stump of its esophageal tube. The Soviet Union proudly boasted that the dog was proof of their nation's medical preeminence.
Over the course of the next fifteen years, Demikhov created a total of twenty of his two-headed dogs. None of them lived very long, as they inevitably succumbed to problems of tissue rejection. The record was a month.
Demikhov explained that the dogs were part of a continuing series of experiments in surgical techniques, with his ultimate goal being to learn how to perform a human heartand lung transplant. Another surgeon beat him to this goal — Dr. Christian Baarnard in 1967 — but Demikhov is widely credited withpaving the way for it.

I got goose bumps just looking at the pictures. That was bizarre! Im not surprised that someone else with a sane method beat him to his goal.
