Puppy with green fur

 On the Italian island of Sardinia, a litter of puppies was born four were white like their mother and one was green, the owner called him pistachio, the owner put the four white dogs up for adoption and kept pistachio.

The rare phenomenon is thought to happen when a light coloured dog comes in contact with biliverdin, 

biliverdin is a green pigment and the same pigment that turns bruises green.

It dyes its fur in the womb and fades over time, although green dogs are rare they are not unheard of in January this year a white german shepherd gave birth to a green german shepherd and in 2017 in Scotland, a golden retriever gave birth to a green puppy.

According to the owners' vet, he got told that “ during the gestation period, biliverdin, a substance from bile, mixes with amniotic fluid from the placenta, staining the weaker puppy.”
