"The male and female pair were part of a litter of five puppies, and were much smaller and weaker than their siblings. The female puppy, however, died shortly after birth. The male puppy is still alive, but is weak and gradually losing its green hue.
This isn’t the first case of a green puppy being born, according to The Huffington Post. A Labrador puppy was born green in England two years ago, but lost its hue after 10 days. The cause of the green coloring was believed to be the result of exposure to a substance in the placenta."
