Fedor Jeftichew was a Russian sideshow performer who performed as "Jo-Jo, the Dog-Faced Boy.”
"By special permit from the Czar of all the Russias, we exhibit for the first and only time in the New World. THE MOST PRODIGIOUS PARAGON OF ALL PRODIGIES SECURED BY P. T. BARNUM IN OVER 50 YEARS. THE HUMAN–SKYE TERRIER THE CROWNING MYSTERY OF NATURE’S CONTRADICTIONS. This Incarnate Paradox, before which Science stands confounded and blindly wonders, was found about thirteen years ago in company with his Dog-Faced Father, living in a remote cave in deep Kostroma Forests of Central Russia. They were first discovered by a hunter, and a party was formed who tracked them to their cave, and, after a desperate conflict, in which the savage father fought with all the fury of an enraged mastiff, their capture was effected. ..."
Jeftichew was successful, and at the high of his popularity he was performing more than twenty shows per day. He also sometimes performed as "The Human Skye Terrier" with a backstory describing him as "a bright boy with a dog's face."
