Chow Chows are a unique and fascinating breed with many distinctive characteristics, but perhaps the most intriguing feature of these dogs is their blue or purplish tongues. While most dog breeds have pink tongues, the Chow Chow stands out with this unusual trait, shared only by a few other animals. This article will dive into the origins, theories, and significance of the Chow Chow’s blue tongue, ensuring that you gain a comprehensive understanding of this rare phenomenon.
The History and Origins of Chow Chows
The Chow Chow is an ancient breed that traces its roots back thousands of years to China. Revered for their loyalty, strength, and regal appearance, Chow Chows were once the companions of Chinese nobility and emperors. They were also used as guard dogs, hunting dogs, and even sled dogs. The breed’s unique physical attributes, including its thick double coat and blue tongue, have long been a subject of intrigue and fascination.
What Makes a Tongue Blue? The Science Explained
To understand why Chow Chows have blue tongues, it’s essential to look at the science behind pigmentation. Most animals, including dogs, have tongues that are pink due to blood vessels showing through the thin tissue. In Chow Chows, however, specific cells produce higher levels of melanin, a pigment that provides color to skin and hair. This melanin concentration is what gives their tongues a blue or purplish hue.
Melanin is responsible for various colors in the animal kingdom, from the dark wings of crows to the stripes on tigers. In Chow Chows, this increased presence of melanin in their tongues is an anomaly compared to other breeds, making it one of their defining traits.
Theories Behind the Blue Tongue Phenomenon
There are several theories regarding why Chow Chows developed blue tongues:
- Genetic Mutation: One of the most commonly accepted theories is that the blue tongue is the result of a genetic mutation that occurred many generations ago. Over time, this trait was passed down through selective breeding, solidifying it as a standard characteristic of the breed.
- Evolutionary Advantage: Some researchers believe that the blue tongue may have provided an evolutionary advantage. It’s thought that the darker color of the tongue might have helped with temperature regulation or protection from certain infections.
- Cultural Significance: In ancient China, the blue tongue of the Chow Chow was seen as a symbol of good luck and power. This unique feature may have made the breed more desirable and led to selective breeding practices that emphasized the trait.
Other Animals with Blue or Dark Tongues
Although the blue tongue is rare among dogs, Chow Chows aren’t the only creatures with this feature. The following animals also share this distinctive trait:
- Shar Peis: Another breed known for their wrinkled skin, Shar Peis also have blue or purplish tongues, although their tongues may not be as uniformly colored as those of Chow Chows.
- Giraffes: Known for their long necks and spotted coats, giraffes have dark, bluish tongues that help protect them from sunburn while they feed on tall trees.
- Polar Bears: Their tongues are typically blue-black, which some scientists believe helps with heat retention in their Arctic habitat.
Is a Blue Tongue in Dogs Always a Sign of a Chow Chow?
It’s a common misconception that a blue or purplish tongue is exclusive to Chow Chows. While it is a hallmark of the breed, there are cases where mixed-breed dogs can also exhibit this trait due to having some Chow ancestry. In addition, other breeds, such as the Shar Pei, can also have a bluish or partially pigmented tongue.
However, in most dogs, a blue or purple tongue can indicate health problems, such as cyanosis, which signals a lack of oxygen. If a dog that is not a Chow Chow or Shar Pei has a blue tongue, it is essential to consult a veterinarian to rule out any health concerns.

What is special about a Chow Chow?
Chow Chows are special for several reasons that set them apart from other dog breeds:
1. Unique Appearance
Chow Chows have a distinctive look, characterized by their thick double coat that resembles a lion’s mane. Their deep-set eyes and upright, rounded ears give them a regal and somewhat aloof expression. The breed’s sturdy build and proud stance contribute to their striking appearance.
2. Blue or Purple Tongue
One of the most unique traits of a Chow Chow is their blue or purplish tongue, which is rare among dogs. This feature, shared only with the Shar Pei, is one of the breed’s most recognizable characteristics.
3. Ancient Origins
Chow Chows are one of the oldest dog breeds, with roots tracing back to ancient China over 2,000 years ago. They were historically used for various purposes, including hunting, guarding, and pulling sleds. Their long history adds to their mystique and allure.
4. Independent Personality
Chow Chows are known for their independent and somewhat aloof demeanor. Unlike many other dog breeds, they often exhibit cat-like behaviors, such as being selective in their interactions and enjoying solitude. This makes them suitable for owners who appreciate a pet with a unique and dignified character.
5. Loyalty and Protective Nature
Despite their independent nature, Chow Chows are deeply loyal to their families. They can be reserved with strangers but are known to form strong bonds with their owners and act as protective companions. This loyalty makes them excellent guard dogs.
6. Grooming Needs
The thick double coat of a Chow Chow requires regular grooming to maintain its beauty and prevent matting. While this requires more maintenance compared to some breeds, it’s also one of the factors that give them their majestic appearance.
7. Intelligence
Chow Chows are intelligent and can be trained, but they require consistent and patient training methods due to their independent streak. They respond best to positive reinforcement and a confident handler.
8. Adaptable to Different Living Environments
Although they have a sturdy build, Chow Chows can adapt well to apartment living as long as they receive regular walks and exercise. They are not known for being overly energetic, which can be a benefit for those who live in smaller spaces.
Overall, Chow Chows are special for their unique combination of physical traits, ancient heritage, and distinctive personality. They are best suited for owners who appreciate their independent nature and are willing to invest time in grooming and training.
The Role of Genetics in Tongue Pigmentation
The presence of melanin in the tongues of Chow Chows is linked to specific genes responsible for pigment production. Studies suggest that these genes influence not only tongue color but also coat and skin pigmentation. Interestingly, Chow Chows often have black or dark-colored gums and noses, which is another sign of higher melanin levels.
Common Misconceptions About the Blue Tongue
Myth 1: All Purebred Dogs Have Pink Tongues
One of the most widespread myths is that only mixed-breed dogs or unhealthy dogs have non-pink tongues. However, the blue tongue in Chow Chows is an exception, representing a breed standard rather than an abnormality.
Myth 2: The Blue Tongue Indicates Illness
While it’s true that a blue tongue in most dog breeds could signal a health issue, this is not the case for Chow Chows or Shar Peis. For these breeds, a blue tongue is completely natural and poses no health risks.
How the Blue Tongue Impacts Breed Standards
In dog shows and competitions, the blue tongue is a vital aspect of the breed standard for Chow Chows. Judges often use this feature to help verify the authenticity of the breed. A purebred Chow Chow must have a completely blue or purple tongue to meet the criteria. If a Chow Chow has a partially pink tongue, it may be disqualified from certain breed competitions.
Maintaining Oral Health in Chow Chows
Just like any other dog breed, maintaining good oral hygiene is crucial for Chow Chows. Regular dental checkups and proper cleaning are necessary to ensure their mouths remain healthy. While the color of their tongue does not impact their health, poor dental hygiene can lead to gum disease and other oral issues. Owners should make sure to:
- Brush their dog’s teeth regularly with dog-friendly toothpaste.
- Provide chew toys that promote dental health.
- Visit the vet for annual dental examinations.
