No published genetic study measures the share of each founding breed.
Neighbouring Chinese breeds (often confused)#
| Breed | Difference |
|---|---|
| Kunming Dog (昆明犬) | Chinese police dog of the German Shepherd type, bred from 1953 by the Kunming police dog base (Yunnan) and declared a success in 1964. Wolf-grey or fawn coat, lighter build. The Laizhou Hong is more massive, black and red-tan, and has had no documented institutional breeding programme. |
| Chongqing Dog (重庆犬) | Red molosser-type dog from Sichuan-Chongqing, very short solid red coat, short muzzle, bamboo-shaped tail. |
| Chuandong Hound (川东猎犬) | Solid red, brachycephalic hunting dog with a very short muzzle, often mistaken for a Laizhou Hong. The Laizhou Hong has a black back and a longer muzzle. On an owners' forum in 2026, many users took a Chuandong imported from China for a Laizhou Hong. The CKU has listed it separately from the Chongqing Dog since 2017. |
| Xiasi Dog | White hunting dog from Guizhou. |
| Tang Dog / Tang Gou | Generic Chinese village dog. |
| Tibetan Mastiff | No connection, despite websites claiming otherwise. |
| Shar Pei, Chow Chow | The only thing in common: the blue/spotted tongue of Chinese breeds. |
Look-alike European breeds#
- Dobermann: the most frequent confusion, in both directions. Same silhouette and same black and tan coat, but the Laizhou Hong is taller and more massive, its ears stand up naturally (the Dobermann's are often cropped), its tail is long and thick and its skull stronger. In China, buyers have suspected that a puppy sold as a Dobermann was a Laizhou Hong (see The Laizhou Hong and the law in China).
- Beauceron: black and tan coat, size, but drop or cropped ears, and double dewclaws.
- Black and tan German Shepherd: a strong resemblance, but the Laizhou Hong has a straight back, a shorter coat, a more molosser-like head and a more intense red.
- Rottweiler: identical colours, but the Laizhou Hong is taller and more slender, with erect ears.
On forums, users also mistake the Laizhou Hong for the Dutch Shepherd or the Malinois.
The false "Soviet Red"#
"Soviet Red Dog" (苏联红) usually refers to the Laizhou Hong. The name is a marketing invention from the 1980s. There is no corresponding Soviet breed. But the name has also been used to sell other black and tan dogs: not every "Soviet Red" is a Laizhou Hong. One Chinese page even makes the "Soviet Red" an ancestor of the Laizhou Hong, crossed with the German Shepherd and good local dogs, rather than a mere nickname. This needs to be explained clearly on the site, as many English-language pages present it as a separate breed.
