Maned wolves are monogamous, though males and females tend to live independently except during the breeding season.
Mating System: monogamous
Little is known about the reproductive patterns of wild maned wolves. Females are monoestrous. Breeding season is probably controlled by photoperiod; captives copulate between October and February in the Northern Hemisphere and between August and October in South America. The estrous lasts for a period of one to four days. Gestation in captivity is similar to that of other canids and lasts approximately 65 days. A litter usually contains one to five young. A record number of seven has been observed. Young are born weighing 340 to 430 grams and develop quickly. Their eyes and ears open by day nine, their ears stand upright and they will take regurgitated food by week four, the pelage changes from black to red by week ten, they are weaned by 15 weeks, and their bodies have the proportions of adults at one year, at which time they reach sexual maturity. Captive individuals have lived 15 years. Non-captive maned wolves give birth in natal nests hidden by thick vegetation. Wild maned wolves are rarely seen with their pups.
