The Mystery of the Chow Chow tongue color

Chow Chow tongue color seems blue-black. The scientific community has been trying to answer this issue for quite some time. Still, they have been unable to find any advantages or benefits associated with having a Chow Chow tongue color blue-black. For humans, this excess melanin shows up as freckles and birthmarks. When dogs of the Chow Chow and other breeds thrust out their tongues, the dots on the tongue or the complete blue-black Chow Chow tongue color reveal this trait.


The Chow Chows originate in East Asia and are said to be related to the Simocyon of northern Mongolia through China. Historically, this creature has been compared to foxes and little bears today. The fact that it possessed 44 teeth was one of its most defining features. Like humans, Chow Chows are born with 44 teeth. However, unlike humans, they lose the additional pair as they mature. On average, 42 teeth are present at birth in all other dog breeds. The Chow Chow bear’s distinctively blue-black tongue is shared only by a few other tiny bears native to the same area.

Fetal Pinkness

In contrast to popular belief, Chow Chow pups do not automatically get their bright tongues at birth. Like the tongues of most other dog breeds, theirs is pink when they’re first born. The first signs of blue-black pigmentation appear between 8 and 10 weeks. The Chinese Shar-Pei is the only other breed that often develops a similar color. While blue-black tongues are common in both of these breeds, they are by no means universal. Some people get a few colorful spots on their tongue, and their natural pink hue remains unaffected.

Is It a Purebred or a Mutt?

Since the Chow Chow is such a long-standing breed, we can tell purebreds from mixes by looking at their tongues. Between 8 and 10, a purebred Chow Chow’s tongue becomes a distinctive blue-black shade. A Chow mix can acquire blue-black patches or cannot change color.

The Chow Chow is the only dog breed for whom this way of distinguishing between purebreds and hybrids exists. When determining a dog’s lineage, the tongue color is used in a way that has never been done before.

Nature of a deep blue-black

This unusual tongue coloring is more frequent in animals than is often believed. There are a lot of kinds of animals that look like this. Some are well-known, and the logic behind them has been shown. The blue-black tongue continues to baffle some people. Giraffes, Okapis (of the same family as giraffes), and Polar Bears all have dark blue or black tongues. Some are lighter in the shade, while others have tongues that are almost as dark as their skin.

Blue-tongued dog breeds

According to the American Kennel Club, only two dog breeds, the Chinese shar-pei, and the chow, are known to have blue-black tongue. A chow to meet breed standards; its tongue must be completely blue-black, with the darker, the better. Given the importance of the blue-black tongue to the identification of this breed, the American Kennel Club disqualifies dogs if their tongues have any red or pink coloring on the top surface or margins or if they have any patches of color on the tongue.


Numerous hypotheses have been put out to illuminate this riddle, but we may never find the truth. Since this breed existed before the Han Dynasty in 202 BC, we may never know the explanation behind this intriguing genetic anomaly.
