The Donggyeong, a poorly known dog from Korea

Native dogs of Korea

The Cultural Heritage Administration (Korea) registered the Donggyeong breed on its list of natural monuments in 2012. This is a state-designated heritage classification for animals, plants and biological and geological features carrying exceptional historical, cultural, scientific, aesthetic or academic value. The Jindo and the Sapsal dogs had been previously given this designation (see photos to the left).

The oldest reference to the Donggyeong is in The Chronicles of the Three Kingdoms, a book about Korea’s Three Kingdoms era, a period between the fourth and seventh centuries, and written during the Goryeo period (918-1392). One of the chapters of the book, “Assorted Information on the Donggyeong,” is dedicated to the dog. The Donggyeong was also a model for dogs appearing on earthenware made by during the Silla Dynasty (B.C. 57-935).

At first glance, the Donggyeong looks very similar to the Jindo. However, the key distinction is in the tail: While the Jindo’s tail is long and curved, the Donggyeong has a bobtail or completely lacks a tail.

In 2007 locals initiated a project to preserve the breed, forming an organization called the Korea Preservation Association for Gyeongju Dog Donggyeong and started breeding the dog in Gyeongju. Today, there are some 306 Donggyeong dogs which are officially recognized by the CHA.

In a forthcoming paper in the Journal of Veterinary Medical Science (Japan) Gil-jae Cho and colleagues analyze 10 microsatellite markers in the Donggyeong dog and compare it to 12 other dog breeds (369 individual dogs). The number of alleles per locus varied from 5 to 10 with a mean value of 7.6 in the Donggyeong dog. This study found specific alleles in the Donggyeong dog when compared with other dog breeds. Also, the results showed two Korean native dogs cluster together while other dog breeds form a distinctly different cluster. The closest distance (0.1184) was observed between the Donggyeong and Jindo suggesting a common ancestor.

This Blog

This blog is about dogs, dog-human relationships, and my thoughts on the origins and the domestication of dogs. When I say my thoughts, it needs qualification because much of the writing is not the result of my original thinking, but of reading research and anecdotes about dogs and humans, studies of fossils and archeological remains, anatomy, DNA, and behavior. The posts will be documented in standard fashion with author and date, and the literature cited and references are listed on a reference page or at the bottom of the post. The title comes from William Youatts’ 1846 [1857 edition] book, The Dog. On page 14 he wrote, "The dog is the only animal that is capable of disinterested affection. He is the only one that regards the human being as his companion, and follows him as his friend; the only one that seems to possess a natural desire to be useful to him, or from a spontaneous impulse attaches himself to man." Youatt’s book is remarkably insightful for the mid-19th century; he opens Chapter 1 with a comment about dogs being the most intelligent animal other than humans; notes the emotional attachments dogs and humans form, including the sense of loss when dogs loose the humans they have bonded with; and supports the idea that dogs were descended from wolves. This is an idea that was rejected and re-accepted numerous times in the 19th and 20th centuries, and one that will be discussed here.
