How to tell if it's Sha Pigou?

Generally speaking, Sha Pigou's "wrinkles" are deep, and portable leather dogs won't bark, while fake Sha Pigou's "wrinkles" are artificial, not only shallow, but also bark because of pain; The real Sha Pigou's hair is very smooth, so it is not appropriate to touch it with your hands, while the fake Sha Pigou's hair feels rough because it has been pushed by a razor. The lines of the fake Sha Pigou are artificial, so when it grows to a certain extent, the lines on the body will naturally disappear.

Shapigou, a folk tunnel, is called "Hulutou" in shape and "Goose Head" in posture. It has a head like a goose and is very alert. "It's not like a foreign wrinkled dog. It can only walk with its head down and dare not look up when it is hit by something." Sha Pigou's mouth is called "crock mouth" and has "shell ears", which are short and curled forward to prevent being bitten when fighting. Shape, Sha Pigou is a "five-short figure", and its length-height ratio is between 8.5 ∶/8.5∶ 10 ~ 9∶ 10-0/0, which is close to a square. Shapi's legs are described as "cart legs", and the joints of the legs look like "S" bends, with good toughness and good running. The back bone is short and the tail is close to the back, so the anus is slightly upward and relatively large.
