 The canid genus is influenced by the photoperiod and generally reproduces in the springtime.Domestic dogs are not reliant on seasonality for reproduction in contrast to the wolf, coyote, Australian dingo and African basenji that may have only one, seasonal, estrus each year.Feral dogs are influenced by the photoperiod with around half of the breeding females mating in the springtime, which is thought to indicate an ancestral reproductive trait not overcome by domestication, as can be inferred from wolves and Cape hunting dogs.
