The color is the result of a pigment in the bile that surrounded the animal when it was just an embryo.
Surprise on a farm in Sardinia, the large italian island in the Mediterranean Sea. A labrador gave birth to four puppies and one was born greenish.
“When I went to check on the dog, I noticed that she had given birth, but one of the dogs had an unusual color: it was green,” says farmer Cristian Mallocci, from Palu 'e Carru, in the province of Oschiri.
“He looked like an alien dog”, he commented with a laugh.

According to him, the first assumption was that the dog had given birth on the lawn. “As soon as we held the puppy in our hands we understood that it was the color of its fur, it was really green. We couldn’t believe our eyes.” At that point, they decided to call it pistachio.
The two looked for explanations on the internet. The animal's strange color is given by biliverdin, a substance that mixes with the mother's amniotic fluid during birth and is usually ingested by the weaker puppy.
The greenish tone will soon disappear, but pistachio He's already famous.
