Explore Blue-Tongued Dogs: Breeds & Unique Traits
Have you ever seen a dog stick out its tongue, only to reveal a surprising blue hue? If so, you’ve encountered one of nature’s most fascinating canine features. In this post, we’ll explore the world of blue-tongued dogs, uncovering which breeds exhibit this unique trait, the science behind it, and what it means for our furry friends’ health.
What Causes a Blue Tongue in Dogs?
The blue tongue phenomenon in dogs is primarily attributed to genetics and pigmentation. Just as some dogs have black, brown, or pink skin, a select few are born with blue-black pigmentation in their mouths. This is caused by a higher concentration of melanin, the same pigment responsible for skin and hair color.
Interestingly, dogs aren’t the only animals with blue tongues. Giraffes, for instance, also sport this unique feature, though for different evolutionary reasons.
Blue Tongued Dog Breeds
Chow Chow: The Blue Tongue Poster Child
When most people think of blue-tongued dogs, the Chow Chow immediately comes to mind. This ancient Chinese breed is famous for its blue-black tongue, which is present in nearly 100% of purebred Chow Chows.
Fun Fact: In ancient China, Chow Chows with the darkest tongues were considered the most valuable.
Shar Pei: Another Blue Tongue Beauty
While not as well-known for this trait, the Shar Pei is another breed that frequently sports a blue tongue. Like the Chow Chow, this wrinkly wonder hails from China and shares many genetic similarities with its fluffy cousin.
Other Breeds with Partial Blue Tongues
Several other breeds may exhibit partial blue tongues or blue-black spots on their tongues:
- German Shepherd
- Eurasier
- Thai Ridgeback
- Tibetan Mastiff
It’s important to note that in these breeds, a fully blue tongue is not a standard trait and may indicate mixed ancestry.
Blue Tongues in Popular Culture and Dog Shows
The distinctive blue-black tongue of certain dog breeds has left its mark not only in the world of canine enthusiasts but also in popular culture and history. Let’s explore the fascinating role these unique tongues have played in various aspects of society.
Historical Significance in Certain Cultures
In ancient Chinese culture, blue-tongued dogs, particularly Chow Chows, held a special place of reverence. These dogs were often associated with royalty and nobility, with some legends suggesting that the Buddha himself gifted blue-tongued dogs to his followers.
In some Native American tribes, blue-tongued dogs were considered sacred and thought to possess spiritual powers. These animals were sometimes used in healing rituals and were believed to have the ability to ward off evil spirits.
How Blue Tongues are Judged in Dog Shows
In the world of competitive dog shows, a blue-black tongue is an essential breed standard for Chow Chows and Shar Peis. Judges pay close attention to the color and consistency of the tongue:
- For Chow Chows, the ideal tongue color is a solid blue-black, extending to the lips and mouth.
- Shar Peis are expected to have a solid blue-black tongue, although some diluted lavender color is acceptable.
- Spotted tongues or pink areas can be considered faults in these breeds, potentially affecting the dog’s score.
It’s worth noting that for other breeds where blue tongues occasionally occur, such as German Shepherds or Thai Ridgebacks, the tongue color is not typically part of the judging criteria.
Famous Blue-Tongued Dogs in Media or History
While individual blue-tongued dogs haven’t achieved widespread fame, the trait itself has made appearances in popular media:
- Martha Stewart’s Chow Chows: The lifestyle guru has owned several Chow Chows over the years, often featuring them in her shows and magazines, bringing attention to their distinctive blue tongues.
- “Tongue of Blue” in Literature: In the children’s book “Tongue of Blue” by Marian Hertz, a Chow Chow’s blue tongue plays a central role in the story, teaching children about accepting differences.
- The Hangover Movie: While not a major plot point, the Chow Chow featured in “The Hangover” film series drew attention to the breed and its unique tongue coloration.
- Imperial Guard Dogs: Historically, Chow Chows with their blue tongues served as guard dogs for Chinese emperors, adding to their mystique and prestige.
While blue-tongued dogs may not be Hollywood stars in their own right, their unique feature continues to captivate dog lovers and the general public alike, ensuring their place in both canine history and popular culture.
The Genetics Behind Blue Tongues
The blue tongue trait is inherited and believed to be caused by a dominant gene. This means that if a dog inherits the blue tongue gene from either parent, it will likely display the trait. However, the exact genetic mechanisms are still being studied by canine researchers.
Health Implications of Blue Tongues
A blue tongue itself is not a health concern for dogs. It’s simply a unique physical characteristic, much like blue eyes in humans. However, it’s crucial to distinguish between a naturally blue tongue and one that has changed color due to health issues.
When to Be Concerned
If your dog’s tongue suddenly changes color or appears blue when it wasn’t before, it could indicate:
- Cyanosis (lack of oxygen)
- Circulation problems
- Respiratory issues
In these cases, seek veterinary attention immediately.
Caring for Dogs with Blue Tongues
Caring for a blue-tongued dog doesn’t require any special considerations beyond regular oral hygiene. However, the unique coloration can make it harder to spot dental issues, so regular check-ups with your vet are essential.
Appreciating Canine Diversity
Blue-tongued dogs remind us of the wonderful diversity in the canine world. Whether your dog’s tongue is pink, spotted, or blue, each pup is unique and deserving of love.
