What is the history of the Manchu taboo against eating dog meat?

Originated from the customs of Manchu ancestors. Zhao Hong, "a brief discussion of the dietary practices of the Manchu culture" that: "examining the historical records, because the ancestors of the Manchu people in ancient times in a long period of fishing and hunting life, the dog played an important role in people's economic life, and then the people could not bear to kill and eat their meat, and gradually formed a taboo on eating dog meat customs." This statement seems to make sense, because the custom is formed in the practice of long-term production and life. According to this statement, the ancestors of the Manchu people have not eaten dog meat.

We know that the ancestors of the Manchu people are female real people. If the female Zhenren do not eat dog meat, this statement is established, however, the fact is not so. The Southern Song Dynasty Ma Guo "Ma Zhai since the narrative" book wrote about the "Jin early female customs", the book said: "meet the Bone and the sheikhs **** food, then in the kang with a short table or a wooden plate connected to the people set taoliang rice bowl, plus dagger on it, columns of finely chopped leeks, wild garlic, long claws, are salted, not to wooden dishes containing pigs, goats. ...... dog ...... toad and other meat, or burnt, or cooked, or raw sliced meat ...... "Bone beat is the Wanyan Department of female real people, is the founder of the great Jin State. In their feast table with dog meat, in the eating method that can be burnt and roasted, and can be cooked, can also be eaten raw. This clearly negates the ancestors of the Manchu - the female Zhen people already have the custom of not eating dog meat.
