Kermit the Frog once said it's not easy being green. Now, a dog knows how it feels!
A Golden Retriever in the UK just had a litter of nine puppies, and one of them came out green.
Vets believe a pigment in the mom's reproductive system stained the pup's fur.
The phenomenon is extremely rare.
The dogs' owner has named the green puppy "Forrest" and plans to keep him.
