Jackal–dog hybrid

• Hybridization between golden jackals and grey wolves has been detected via mtDNA analysis of golden jackals in Bulgaria. Similar matings between the two species have never been directly observed.
• Golden jackal–dog hybrids can resemble grey wolves in appearance, sometimes being mistaken for wolves by trained biologists. Some genetically pure golden jackals have displayed remarkably grey wolf-like phenotypes.
• The jackal–dog hybrid has an exceptional sense of smell and is highly trainable. It was bred for seven generations to establish the breed, resulting in the Sulimov dog.
• First-generation hybrids of jackal and dog show dominant jackal characteristics, having straight ears, hanging tails, lack of barking, and wild temperaments. These traits were noted by Marie Jean Pierre Flourens in his crossbreeding experiments.
• The hybrid female mated with a terrier and produced five pups. This occurred after initial attempts were hindered by her lack of interest in other dogs.
• The Jackal–dog hybrid can resemble either parent, with two specimens looking like jackals but having rounded ears and different coloration, while a third looked more like a dog, lacking the jackal's conjoined middle paw pads and having dewclaws and a white coat with brown patches. This last specimen was likely the pup of the female, which had backcrossed with a stray Istrian Shorthaired Hound.
• The Sulimov dog is trained from puppyhood to recognize 12 components of explosives. Unlike more common sniffing dogs, it takes the initiative in searching.
• Male jackal pups were fostered on a Lapponian Herder bitch at the start of the breeding process to imprint jackals on dogs. Female jackals accepted male dogs more easily.
