Unfur-gettable: Puppy with green fur born in Sardinia

Pistachio is part of a five-dog litter and all his siblings have white fur, the same color as their mixed breed mom. The very rare fur color is believed to occur when pale-colored puppies have contact in their mother's womb with a green pigment called biliverdin, which is what causes the green color in bruises.
