According to The Sun U.K., one lucky green puppy was recently born to a Golden Retriever named Rio in the town of Golspie in the Scottish Highlands.
The pup was named “Forest” by her owner, Louise Sutherland, due to her uniquely colored fur. Forest is one of nine puppies, all the rest of whom have completely normal fur.
According to a 2014 article in TIME, veterinarians believe that exposure to biliverdin — a green bile pigment found in the placenta — may be the cause.
“The color has faded quite a bit already and will be gone soon, I’m told,” said Sutherland, and the TIME story backs this up. Apparently the condition tends to resolve itself within a few weeks.
In the picture below you can see that his fur is now barely tinted green.
Forest is an alright name for the pup, but if it had been up to me I would have went with "Grinch." Or maybe even "Frog." Either way, what a special puppy! This condition has only been known to happen three other times in the world.
