When a dog owner in Canton, North Carolina, first saw her new puppy, she knew exactly what to name him. Hulk the infant pup is much smaller than his namesake, but like the comic book character, he's green from head to toe.
As WLOS reports, Hulk was born with a coat of fur the color of avocado toast. He is one of eight puppies in a litter a white German Shepherd named Gypsy delivered the morning of January 10. Even though one came out lime-green, it was healthy, normal birth, according to Gypsy's owner Shana Stamey.
Hulk's unique coloration isn't a sign of any health issues. Meconium—or the matter in the intestines of a fetus—is mostly made of water, but it can also contain something called biliverdin. This chemical makes bile, and when it gets into the amniotic fluid of a birth sac, it can stain a puppy's fur green. This is especially noticeable when the newborn's fur is white, as in Hulk's case. You can see the rare phenomenon in the video below.
After a few weeks of baths and licks from mom, the meconium stains will eventually fade to reveal his natural white coat. But while he won't be green forever, Hulk gets to keep his colorful name for life.
