The birthplace of the thin dog is not very detailed. There are two theories so far. One is a native dog in Shandong, China. It was later divided into Mongolian thin dog, Shaanxi thin dog, Hebei thin dog and Shandong thin dog. Regardless of whether it is correct or not, at present, the best thin dogs are mainly found in Shandong, China. One type originated from Egypt, because this kind of slender dog appeared in many ancient Egyptian murals. Later, it was not until the Western Han Dynasty that slender dogs were introduced to our country, because the earliest record of slender dogs in China was in the Western Han Dynasty. , but this statement has not been confirmed, but it is undeniable that thin dogs have existed in our country for a long time.
