The common raccoon dog (Nyctereutes procyonoides) is a canid indigenous to mainland East Asia and northern Vietnam. It is also known as the Chinese raccoon dog, Asian raccoon dog, mangut (its Evenki name), neoguri (its Korean name) or simply raccoon dog. It is one of two extant species in the genus Nyctereutes, alongside the Japanese raccoon dog (N. viverrinus).The raccoon dog is named for the resemblance of its masked face to that of the North American common raccoon (Procyon lotor). The closest relatives of the raccoon dogs are the true foxes, not the raccoon, one of the musteloids, which are not closely related. Among the Canidae, the raccoon dog shares the habit of regularly climbing trees only with the North American gray fox, which is not a true fox and to which the raccoon dogs are not closely related.Due to the fur trade, the common raccoon dog has been widely introduced in Europe, where it has been treated as a potentially hazardous invasive species. In Scandinavia, it is called "marten-dog" (Swedish: mårdhund, Norwegian and Danish: mårhund). In Europe, the raccoon dog is included since 2019 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.
