They revered and buried dogs during the Jomon period, but the practice of eating dogs began from the Yayoi period, signifying a change in regime or influx of new foreign lineages from the continent, bringing with them new customs. See Masayuki Manabe’s exerpted commentary below:
“Eating of dog meat by the Japanese
Take dogs, for example. The majority of Japanese these days feel repelled at the thought of eating dog meat, and yet it was a common food in Japan from the Yayoi period right up until the Edo period. During the Jomon period there were many examples of careful burials of canine hunting partners, but hardly any such burials took place in the Yayoi period. The spread of rice cultivation made hunting less important and so dogs became less useful, coupled to which the custom of eating dog meat was introduced from the continent, and so they became a food source. Archeological excavations of the ruins of the residences of feudal lords and the like have revealed large quantities of bones of dogs that were clearly used for food, showing that the custom of eating canine meat continued into the Edo period. It is likely that this meat was not only eaten by humans but also used for feeding falcons. The custom of eating dog meat seems to have survived for some time in the Meiji period, too, as Roka Tokutomi writes in Mimizu no tawagoto [Gibberish of an Earthworm] about his grief for his pet dog Obuchi who was eaten by Satsuma troops during the Satsuma Rebellion. On the other hand, numerous woodblock prints and other paintings clearly show that many dogs were cared for as pets from the Edo period. The shogun Tsunayoshi Tokugawa’s Edicts on Compassion for Living Things hardly needs to be mentioned, and during the time of the eighth shogun Yoshimune Tokugawa people were executed for eating dog stew. At the sites of residences of feudal lords, the bones of dogs probably used for food have been found as well as the bones of dogs that have been buried with care.

There appears to be a divide between Indo-European/Caucasian dog-beliefs and East Asian regarding their respective ritual practices. Indo-European/Caucasian dog beliefs relate to their role as companions or guides to dead humans in the Underworld.
Dog bones at Russian site may indicate ancient warrior initiation
Researchers say the bones of dogs and wolves at the Bronze Age site of Krasnosamarskoe in Russia’s Volga region reveal a rite of animal sacrifice. Archaeologists from Hartwick College in Oneonta, N.Y., speculate that young boys were initiated as warriors by killing the dogs, who had most likely been their pets for years. The sacrifice would make sense, said researcher Dorcas Brown, because “you have to train people to kill.” National Geographic News (5/14)

Buried Dogs Were Divine “Escorts” for Ancient Americans by Anne Casselman (National Geographic News April 23, 2008)
Hundreds of prehistoric dogs found buried throughout the southwestern United States show that canines played a key role in the spiritual beliefs of ancient Americans, new research suggests.
Throughout the region, dogs have been found buried with jewelry, alongside adults and children, carefully stacked in groups, or in positions that relate to important structures, said Dody Fugate, an assistant curator at the Museum of Indian Arts and Culture in Santa Fe, New Mexico.
Fugate has conducted an ongoing survey of known dog burials in the area, and the findings suggest that the animals figured more prominently in their owners’ lives than simply as pets, she said.
“I’m suggesting that the dogs in the New World in the Southwest were used to escort people into the next world, and sometimes they were used in certain rituals in place of people,” Fugate said.
To conduct her research, Fugate collected data on known dog burials and urged her archaeologist colleagues to note when canine remains were found during excavations.
“I have a database now of almost 700 dog burials, and a large number of them are either buried in groups in places of ritual or they’re buried with individual human beings,” she said.
Many of the burials are concentrated in northwestern New Mexico and along the Arizona-New Mexico border, she said (seemap).
“All of that area was full of doggy people,” she said.
She reported her findings at the annual meeting of the Society for American Archaeology in Vancouver, Canada, last month.
1,900 Years of Burials
Fugate’s database indicates that dog burials were most common between 400 B.C. and A.D. 1100.
“The earlier the [human] burial, the more likely you are to have dog in it,” Fugate said.
By the 1400s and 1500s the practice of burying people with dogs had stopped. Indeed, she noted, today’s Pueblo and Navajo Indians believe it is improper to bury dogs.
What the ancient dogs looked like is an open question, she said, but their remains suggest that they were far more diverse than was previously believed.
Fugate has seen remains of ancient canines with floppy ears and pointed ears, long tails and curly tails, small builds and lanky ones.
There were even white ones, found buried on the Arizona-Utah border, whose fur was used to weave ritual garb, she noted.
“They were a motley crew,” she summed up.
Archaeologists’ Best Friend?
Susan Crockford is a zooarchaeologist at Canada’s University of Victoria who has studied dog breeds in the Pacific Northwest.
She agreed that dog remains have often been overlooked during archaeological excavations.
Archaeologists tend to examine animal bones at excavation sites with an eye to what humans were eating, rather than what their relationships with dogs were like, she said.
“Because dogs are very seldom come across in a way that suggests they were used for food, they tend to get dismissed as being not very significant … so they tend to not be reported in very much detail,” Crockford said.
Crockford suggested that dogs’ spiritual role was among their most important functions in the region, second perhaps to their value as hunting or herding companions.
“Basically [ritual dog burial] is a pattern that’s found around the world, and [Fugate]’s doing some really important work in documenting in detail the instances of that phenomena in her part of the world,” Crockford said.

For her part, Fugate said the data she is collecting will give dogs their day as key players in understanding the past.
“Not thinking that dogs might have had a religious relationship [with people] as well means that you’re leaving out a chunk of [ancient] religion,” she said.
“If [you make that assumption], you are losing enormous amounts of information about the ritual context and the mindset of these people.”

Dog burial customs may have originated in the ancient Near East where they are found to have been most prevalent practices, as a connection has been revealed via canine DNA studies.
