The dog of Christian Maloci, the farmer in Sardinia, Italy, gave birth to 5 puppies. One of the puppies is green. Reuters writes about the rare occasion.
Green puppies are a great rarity. The fur took on this color, presumably after contact with the bile's green pigment while being in the mother's abdomen.
The puppy was called pistachio because of its color.
Slowly the fur will change color and will no longer be green.
