Why Do So Many Breeds Have Chow Chow Ancestry?

By

A Chow Chow dog runs through a field with their blue-black tongue sticking out.

People are often surprised to learn their dog has some Chow Chow ancestry. Why are Chows common in mixed-breed dogs, but uncommon as purebreds? Learn more about this surprisingly common breed result with Embark’s Chief Science Officer, Dr. Adam Boyko.

Chow Chows were popular in the 1980s

Although we don’t see as many purebred Chows today, Chow Chows used to be very common. This ancient breed soared in popularity in America, becoming one of the most popular breeds in the 1980s.

They may be less popular today, but Chow Chows used to be prevalent in pop culture. Celebrity Martha Stewart famously has had multiple dogs in her family, including Chows named Genghis Khan, Chin Chin, Paw Paw, Max, and Zu Zu. 

Even as recently as 2022, these celebrity Chows were in the news. Buddakan, the offspring of Stewart’s dog Genghis Khan, won Best in Breed for the Chow Chow at the 2022 Westminster Kennel Club Dog Show.

Chow Chow ancestry is more common than you think

As a result of the breed’s popularity decades ago, we see small amounts of Chow Chow ancestry in many mixed-breed dogs today.

“Your dog’s smile can clue you in,” says Dr. Adam Boyko. “Chow mixes often have black spots on their tongues.”
