The Chinese shar-pei has wrinkled skin and a hippopotamus-like snout.
The shar-pei should have a solid blue-black tongue. Skin, ear, eye, luxating patella, and hip abnormalities are all possible in this breed.
Chow chow tongues should be dark blue-black. Spotted tongues are not allowed in Chow Chow breed standards.
Because of their blue-black tongues, the chow chow and shar-pei may be linked.
The blue tongues of the Eurasier, which was developed in Germany in the 1970s from the wolf spitz, samoyed, and chow chow, are either solid or speckled.
Eurasiers are popular home pets. The laid-back breed is active outside yet calm within. They cherish their families, however. This breed responds well to positive reinforcement training.
Thai ridgebacks are rare and ancient hunting and guard dogs that originated in Thailand around 300 years ago. Black tongue marks, whether spotted or solid, are preferred.
The Thai ridgeback is a medium-sized dog with short hair and a ridge—a line of hair that grows down the back in the opposite direction as the rest of the coat.
