An Italian farmer welcomed a litter of five dogs earlier this month — and one of the pups stood out among the rest. Cristian Mallocci couldn't believe his eyes when one of them was born with green fur.

Mallocci's dog, Spelacchia, gave birth to four other dogs with white fur, the same color as hers. Spelacchia is mixed-breed, but that doesn't explain why one of her pups came out with green fur, CBS News reported.
The strange pigmentation is believed to occur when pale puppies come in contact with biliverdin in their mother's womb, according to Reuters. Biliverdin is also the pigment that makes bruises sometimes appear green.
