An animal rescue shelter in Missouri has taken in an abandoned puppy that has a second tail growing from the middle of its head.

Photos of the 10-week-old pooch — which the staff at Mac’s Mission has named “Narwhal” — have gone viral, amassing tens of thousands of likes on Facebook.

Just another video of our narwhal the magical fuzzy unicorn puppy because we think he is amazing. (We are not accepting applications for him right now until we are very certain his unicorn horn is not going to have a growth spurt and become an issue) (no it does not wag) (yes he is keeping it) (yes he is amazingly awesome!!)

Veterinarians have X-rayed the dog’s second tail and found it isn’t attached to anything vital. But because it doesn’t cause Narwhal any pain, they’re not going to surgically remove it.

What’s the weirdest looking pet you’ve seen?
