There is little fighting among males for mates. ( Kauhala, et al., 1993 Sheldon, 1992)ĭuring mating, females are courted by 3 to 4 males. Polygamy has been reported in captive individuals. In regions of home-range overlap, pairs do not interact. Studies have shown that raccoon dogs form mating pairs from year to year, and monogamy among pairs has been reported in raccoon dogs found in Finland. Not much is known about the mating behavior of N. Raccoon dogs also have a spring molt that begins in April when the underfur is shed. The winter pelage grows in during September, October, and November. Nyctereutes procyonoides goes through a molt in the summer between July and October. ( Sheldon, 1992 Ward and Wurster-Hill, 1990) Winter pelage is thicker and darker than summer pelage. Raccoon dogs have thick, bushy tails that are black dorsally and light-yellow ventrally with a black tip. On the belly, the fur is lighter brown or tan. Long guard hairs, found throughout the dorsal side, are tipped black. Body color is dusky brown to yellow-brown dorsally but varies greatly. Ears are rounded and short black hair one the ears trims the white hair inside. A black marking runs across both shoulders and down the back, forming the shape of a cross. Markings on the head include a white muzzle, white face, and black fur surrounding the eyes. ( Sheldon, 1992 Ward and Wurster-Hill, 1990 Sheldon, 1992 Ward and Wurster-Hill, 1990) Mass of adult females in China and Japan is 0.5kg greater than males. procyonoides may account for this discrepancy. The existence of several subspecies of N. On average, individuals in Europe tend to be larger than those in China and Japan. Body weight ranges from 4 to 6 kg in the summer to 6 to 10 kg in the winter before hibernation. Legs are short, and overall the body is stocky. Length from head to rump is 50 to 68 cm with a tail length of 13 to 25 cm. Raccoon dogs have reduced carnassials and relatively large molars. The dental formula is i 3/3, c 1/1, p 4/4, m 2 or 3/3, total 42 or 44. They have small heads (greatest length 133 mm) with pointed, low-profile rostra. Nyctereutes procyonoides has the appearance of a small fox-like canid with the fur markings similar to those of raccoons ( Procyon lotor). ( Sheldon, 1992 Ward and Wurster-Hill, 1989 Ward and Wurster-Hill, 1990) Nyctereutes procyonoides also has been known to encroach upon human habitats while scavenging for food. Raccoon dogs are found from near sea level to greater than 3,000 m. Regions bordering water are also favored. It prefers forest, forest borders, or dense vegetation- areas of thick underbrush, marshes, and reedbeds- for dense cover. Nyctereutes procyonoides is found in subarctic and subtropical climates. procyonoides is widespread throughout northern and western Europe in countries including Finland, Sweden, Norway, Poland, Romania, Czech Republic, Slovakia, Germany, France, Austria, and Hungary. Between 19, the fur-farming industry introduced from 4,000 to 9,000 raccoon dogs to the European and Asian U.S.S.R. Nyctereutes procyonoides is native to eastern Siberia, northern China, North Vietnam, Korea, and Japan.
