Narwhal is a 10-week old puppy who lives at Mac's Mission, an animal rescue center in Cape Giradeau, Missouri. In addition to his regular, aft-mounted tail, he has a little one sticking out of his forehead. X-rays confirm that it's not connected to anything and offers only decorative function. BBC News quotes Rochelle Steffen, the operator of Mac's Mission:
Narwhal is not yet available for adoption as the staff want him to "grow a bit more and truly make sure the tail doesn't become a bother or a problem".
Ms Steffen said Narwhal was one of hundreds of dogs dumped in rural Missouri.
Those taken in by Mac's Mission, who mostly had special needs - deformities, clefts, trauma, "anything major", would otherwise be more likely to be put down, she said, so "there is a great need to give them a chance".
"We give them that chance."
