This is a two-headed dog that was created in 1959 by Soviet scientist Vladimir Demikhov.. He carried out 23 experiments to develop an anomaly but failed because the dogs kept dying. Finally, in his 24th experiment, he was able to create this two-headed dog.
First, he grafted one dog’s head onto another’s body. He then stitched their circulatory systems together, and connected their backbones with plastic strings. After the procedure was done, both the dog heads could see, hear, swallow and smell.
Unfortunately, or maybe, fortunately, his techniques were still comparatively undeveloped, and the dog died after four days. While there is no doubt that his research was a pioneering venture into head transplantation, experts still debate the ethics of such procedures
