The chow chow is a very peculiar dog that stands out for its blue tongue. It has its origins in China and its name means ‘bloated lion dog’. In addition, although it has a very peculiar language, this animal has many curiosities.
Scientific explanation of the researchers
The explanation for the bluish color of its tongue lies in genetics, since the mucous membranes of this dog have pigment cells that other breeds do not have. These cells have pigments inside them that give them this characteristic color. The chow chow has a greater amount of these cells in its body, which is why the language of this dog is different from that of other animals.
In addition, these cells are not only found on the tongue, but are also located on the mucous membranes, which is why the chow chow is the only breed with black gums, lips and palate.
However, this animal is not the only one that presents this uniqueness. Other species such as giraffes or polar bears also have a greater amount of these pigment cells, although not in the same way as the chow chow. In addition, scientists have not been able to establish a relationship between this breed and other animals.
On the other hand, some scientists argue that this genetic mutation could have been developed by an adaptive evolution of the animal or by an accidental alteration within its genealogical tree.
Other dark-tongued dogs
The chow chow is the only animal with a completely dark tongue, gums, and lips. However, we can find other breeds that also have black lips and palate, such as the Shar Pei. The difference is that their mucous membranes are not totally dark. Likewise, there are more than 30 different races that also have black spots on their tongue.
In addition, this breed does not have to be born with a tongue of this color, but it darkens as it grows, after two or three months. And if the animal is crossed with another breed it is possible that this genetic condition is altered.
Characteristics of this breed
The chow chow has a fairly calm and reserved character. It is a magnificent watchdog, since it originally protected Buddhist temples. They are animals loyal to their family, although they are reserved with unknown people. In addition, in the past, they were also used as sheepdogs, which is why they are always on alert or watching.
As for the care of its coat, the chow chow requires frequent brushing and a specific shampoo for its coat. In addition, it is recommended that they go to the dog groomer once a month to avoid the appearance of knots or skin problems.
