Some dog owners in Italy were pleasantly surprised when their dog had a litter of puppies, all of which were a vibrant white color, except one.

Pistachio, who was born with green fur is the most special good boy of the litter.

Don’t worry though, there is nothing wrong with Pistachio. He was just exposed to a pigment, biliverdin, in the womb.

He will be a happy, healthy and green puppy!
