[32] [33] Hybridization also occurs between female golden jackals and male dogs, which produces fertile offspring, [34] a jackal–dog hybrid. There was 11–13% of ancient gene flow into the golden jackal from the population that was ancestral to wolves and dogs, and an additional 3% from extant wolf populations.
Although no genetic evidence has been found of grey wolf–jackal hybridization in the Caucasus Mountains, some cases exist where apparently genetically pure golden jackals have displayed remarkably grey wolf-like phenotypes, to the point of being mistaken for wolves by trained biologists. [7]
The discovery of these specimens confirmed that hybridization between the two canids occurs in the wild, and that the two have unlimited fertility with each other. [27] Although hybridization between wolves and golden jackals has never been observed, evidence of such occurrences was discovered through mtDNA analysis on jackals in Bulgaria. [28]

Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails.
10 of the 13 extant canid genera left-to-right, top-to-bottom: Canis, Cuon, Lycaon, Cerdocyon, Chrysocyon, Speothos, Vulpes, Nyctereutes, Otocyon, and Urocyon Canidae is a family of mammals in the order Carnivora, which includes domestic dogs, wolves, coyotes, foxes, jackals, dingoes, and many other extant and extinct dog-like mammals.
Baculum of a domestic dog; The arrow points to the bottom groove where the urethra is located. The tip is to the right. Inside the corpus spongiosum lies the baculum.This allows the male dog to enter into the vagina before the erectile tissue is swollen.
