A puppy in Missouri captured the internet's heart for a special reason: Narwhal has an additional tail on his head.
Founder of Mac's Mission rescue Rochelle Steffen, who specializes in special needs dogs with cleft palettes, deformaties, etc., is currently caring for the precious pup.
"We’ve seen some dogs with extra things but not like this," Steffen told BuzzFeed News.
Vets examined Narwhal and found the bonus tail, which has no bones and doesn't move, isn't causing him any problems. Narwhal is otherwise healthy.
"It makes him super special though," she said.
