The Raccoon Dog (Nyctereutes procyonoides, from the Greek words nukt-, "night" + ereutēs, "wanderer" + prokuōn, "before-dog" [but in New Latin used to mean "raccoon"] + -oidēs, "-oid") is a member of the canid family (which includes dogs, wolves, and foxes) and is indigenous to east Asia. It is the only extant species in its genus Nyctereutes. It is considered a basal canid species, resembling ancestral forms of the family. The Raccoon Dog is named for its resemblance to the raccoon (Procyon lotor), to which it is not closely related.
The Raccoon Dog is native to China, Korea, Japan, and Northeastern Russia. Average adult head and body length is about 65 cm (2 ft) and weight ranges from 4 to 10 kg (9 to 22 lb). Average litters are large, 15 or more pups. Longevity is 3–4 years in the wild and up to 11 years in captivity. The species is found in both plains and mountainous regions and is especially common in woodlands. The Raccoon Dog is commonly seen near villages and in rural areas.
Native East Asian Raccoon Dog populations have declined in recent years due to hunting, fur trade and fur trapping, urbanization, an increase of animals associated with human civilization such as pets and abandoned animals, and diseases that may be transmitted between them.[citation needed] Following its introduction into central and western Europe, however, it has been treated as a potentially hazardous invasive species.[3]

[edit] Subspecies
The six recognized subspecies of Raccoon Dog are:[1]
- Nyctereutes procyonoides koreensis (Mori, 1922) found in Korea
- Nyctereutes procyonoides orestes (Thomas, 1923) found in Yunnan (China)
- Nyctereutes procyonoides ussuriensis (Matschie, 1907) found in South Siberia (Russia)
- Nyctereutes procyonoides albus (Hokkaido Raccoon Dog) (Beard, 1904) found in Hokkaido, Japan
- Nyctereutes procyonoides viverrinus (Japanese Raccoon Dog) (Temminck, 1838) found in the rest of Japan
- Nyctereutes procyonoides procyonoides (Temminck, 1838) found in the rest of Asia
There is some debate in the scientific community regarding speciation between the Siberian (N. p. ussuriensis), Chinese (N. p. procyonoides), and Japanese (N. p. viverrinus) subspecies. Chromosome, behavioral, and weight differences, suggest the Japanese Raccoon Dog be considered a separate from the other subspecies.[4][5]
[edit] Behavior
Like many other canids, the Raccoon Dog is omnivorous. However, its diet is atypically diverse, consisting of invertebrates, frogs, lizards, rodents, and birds, along with seeds and berries. Those living near the ocean will also eat crabs and scavenged marine life.[6]
The Raccoon Dog is secretive and not aggressive; it prefers to hide or scream rather than fight, and plays dead to avoid predators. It is monogamous; some fights occur between males for females. Mating season begins when the Raccoon Dog emerges from its winter den. The female is in heat for about six days. The baculum tie in coitus lasts about 6 minutes, less than in other canids.[citation needed] When the cubs are born, after a gestation of about 60 days, the male will assist in rearing, first by providing food to his mate and by caring for the cubs when they are weaned, about 50 days after birth, while the mother gathers food. Raccoon Dog pups continue to nurse even after they begin eating solid food. They are not weaned until eight weeks of age, later than any other canid. They become physically and sexually mature after one year.[6]
The Raccoon Dog is the only canid to hibernate during the cold months, but only those in the northern part of the range do so.[7] It is also unusual in that its curved claws enable it to climb trees; the only other canid with this ability is the gray fox. It does not bark and it turns its tail into an inverted U to express dominance. The Raccoon Dog's teeth are small for a canid.
[edit] Introduction in Europe
Between 1931 and 1955, the N. p. ussuriensis subspecies was introduced to the European Soviet Union as potential fur or game animals and have spread rapidly since. In 1948, 35 Raccoon Dog were introduced in Latvia. The population increased rapidly. In 1960 Latvia officially reported a total of 4,210 Raccoon Dog were hunted.[8] However, speculation exists that the introduction of the Raccoon Dog to Europe brought with it infected ticks that introduced the Asian Tick-borne meningoencephalitis virus.[9]
The Raccoon Dog is now abundant throughout Finland, Estonia, Latvia, and Lithuania, and has been reported as far away as France, Romania, Italy,[4] Switzerland,[10] Denmark, and Sweden.[3]
[edit] Use of fur
An investigation by three animal protection groups into the Chinese fur trade in 2004 and part of 2005 asserts approximately 1.5 million raccoon dogs are raised for fur in China.[11] The raccoon dog comprises 11% of all animals hunted in Japan.[12] Twenty percent of domestically produced fur in Russia is from the Raccoon Dog.[13]
In late 2006, MSNBC reported Macy's had pulled from its shelves and its website two styles of Sean John hooded jackets, originally advertised as featuring faux fur, after an investigation by the nation's largest animal protection organization, concluded garments were actually made from raccoon dog.[14] Sean Combs, the label's founder, said he had been unaware of the material, but as soon as he knew about it, he had his clothing line stop using the material.
On 24 April 2008, The Humane Society of the United States (HSUS) filed a false advertising complaint with the US Federal Trade Commission alleging at least 20 retailers in the U.S. have been mislabeling raccoon dog fur. According to HSUS, racoon dogs are typically skinned alive.[15][16] They assert 70% of fur garments they tested were raccoon dog but were mislabeled as faux fur, coyote, rabbit, or other animals.[17]
In March 2009, following Henry Bendel and Overstock.com, retailer JCPenney became the first major retailer to ban fur products from its shelves.[18] Lord & Taylor followed suit in December 2009.[16]
