As it turns out, there's a big demand for puppies with tails growing from their heads. After photos of a dog named Narwhal went viral on Wednesday, workers at the Mac's Mission animal rescue in Missouri have been swamped with adoption requests. But Mac's Mission owner Rochelle Steffen says the shelter's employees have decided to keep the little pooch, who's been nicknamed "the unicorn dog" by online news agencies. Steffen also says the shelter has received complaints from people who think Narwhal's extra tail should be removed. However, since vets determined the "tail" is really just a fur-covered piece of cartilage, there's no need to perform unnecessary surgery on the puppy. "Since sharing this story they’ve come at us and said, ‘This is terrible. Take it off,'" Steffen says of the extra tail. "But there’s no reason to take it off. He’s 100 percent normal with just a bit of flair on his face." Do you find the head-tail cute or disturbing? If you were adopting a dog from a pound, would you pick one with a tail growing from its head?
