Mama Dog Gives Birth To A Green Puppy, And It's Not The First Time It's Happened

When Elaine Cooper found out her dog, Milly, was expecting puppies, I bet she never expected a green one.

Yep, you read that correctly. A green puppy.

Milly, a chocolate Labrador, gave birth to four male puppies and one female one. But it wasn't just gender that separated the pups.

The green puppy was affectionately named Fifi after the ogre Princess Fiona from Shrek.

Elaine Cooper did some research on the condition and found out that there are only two other documented cases of this. Fifi is almost one of a kind!

Cooper said she and her husband didn't think too much of it at first. But after some research, they realized what a rarity they came across.

But will her puppy be green forever?

The green color is caused by a green bile pigment found in the placenta called biliverdia. Overexposure to this while in the womb can cause the discoloration of a puppy.

"She came out in the sack so we thought that it was the placenta that made her look very dark. We thought she was a black Labrador. But when Milly started to lick the placenta off she actually had a green tinge. We were laughing and saying no, this can't be green. All the others are golden and this one's green. It's to do with the placenta, so it's a phenomenon, it's just very rare in dogs. We were a bit shocked, then laughed and thought, "Oh my, is it OK"."

But if you were hoping this puppy was going to remain a mint-chocolate Labrador forever, you're out of luck.

"The colour's faded now and she's doing well even though she was the smallest of the litter," said Cooper. "She's so sweet."
