Mother of dog Rio had just given birth to nine puppies in the Scottish Highlands town of Golspie when owner Louise Sutherland noticed something about one of the puppies.
One of nine was a very distinct shade of green.
The puppies were born July 7. Sutherland said she couldn’t believe what she was seeing. The little male puppy was named, fittingly, Forest.
The rare phenomenon is thought to happen when light-colored puppies come in contact with biliverdin, a green pigment found in bile. It’s the same pigment you can see when bruises turn green. It essentially dyes their fur in the womb, and the color fades over time.
