The sentence you deleted says"dog is NOT AS WIDELY consumed as beef, chicken, and pork" Although the fact that dog meat comes 4th after beef, pork, chicken (In the "meat" section, the author claims their popularity has been in this order in Korea.) in the original quotation shows the importance of dog meat. (Wild animals are mentioned after dog meat).
And what about the other two Petitt citations which you deleted, but which were proved as correct sources? Seems to me that you just want to blank all contents on dog meat consumption from this article.
Oh, and another quotation from Petitt that puts dog meat along with beef, pork, and chicken: "When you see a fat cow, dog, pig, or chicken, do not immediately speak of slaughtering, cooking, and eating it." (p.158, explaining traditional dining etiquettes).
