Folk proverb: Eat dog meat on the dog days to ward off the heat, and eat dog meat on the 39th day to ward off the cold.

In ancient times, dog meat was not only served on the banquet, but also a delicacy. Dog meat was not served on the banquet until after the Song Dynasty.

Dog meat is also called "fragrant meat" or "ground sheep" in some areas of China. It is also called "Sanliu Xiangrou" in Cantonese-speaking areas, because three plus six equals nine, and "nine" and "dog" have the same pronunciation in Cantonese. Dog meat not only has high protein content, but also has excellent protein quality, especially a large proportion of globulin, which has a significant effect on enhancing the body's disease resistance, cell vitality and organ function. Eating dog meat can strengthen human body, improve digestion, promote blood circulation and improve function. Dog meat can also be used to treat the frailty of the elderly, such as incontinence of urination, cold limbs, and lack of energy. Eating it often in winter can enhance the ability of the elderly to resist cold. According to traditional Chinese medicine, dog meat has the effect of warming and nourishing kidney yang.
