European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Golden jackal
In Transcaucasia, golden jackal pups are born from late March to late April, and in northeastern Italy during late April; they can be born at any time of year in Nepal. The number of pups born in a single litter varies geographically. Jackals in Transcaucasia give birth to 3–8 pups, Tajikistan 3–7 pups, Uzbekistan 2–8 pups, and Bulgaria 4–7 pups; in India the average is four pups. The pups are born with closed eyes that open after 8–11 days, with the ears erecting after 10–13 days. Their teeth erupt at 11 days after birth, and the eruption of adult dentition is completed after five months. Pups are born with soft fur that ranges in color from light gray to dark brown. At the age of one month, their fur is shed and replaced with a new reddish-colored pelt with black speckles. The pups have a fast growth rate and weigh at two days of age, at one month, and at four months. Females possess four pairs of teats, and lactation lasts for up to 8–10 weeks. The pups begin to eat meat at the age of 15–20 days.
