One puppy really stands out from the litter. Farmers in Sardinia, Italy were pleasantly surprised when they saw this little guy with his coat of green fur, while his siblings all had glowing white fur like their mom. They appropriately named him Pistachio. Puppies with green fur are extremely rare, but they're not sick. It is believed that while they are in the womb, they come into contact with a pigment called biliverdin.
