Pet dogs generally refer to dogs that do not have proof of ancestry or are only single-born certificates. If they apply for registration of birth medical certificates in CKU/NGKC, they must have proof of ancestry between parents and each other.

行 refers to the hybrid descendants of two or more different species of dogs. Chuanchuan can combine the high-quality characteristics of the parent and maternal body, prevent some genetic diseases caused by artificial reproduction, or improve the dog's immunity and resistance, and can also cultivate some more prominent species, such as independently shaped species. Kunma dogs, which inherit the wolf culture of Kunming dogs well, but also have the gentleness and intelligence of East German Collie. Many people feel that Chuanchuan is not a pure type, and its influence is relatively low. In fact, Chuanchuan's descendants are no less inferior to those of purebreds.
