Its habits are similar to those of other grey wolf subspecies, though the Indian wolf generally lives in smaller packs rarely exceeding 6-8 individuals, and is relatively less vocal, having rarely been known to howl. Indian wolf vocalization includes howls, howl-barks, whimper, social squeals, and whines with howls an average fundamental frequency of 422 Hz and whines 906 Hz. There is at least one record of a lone wolf associating with a pair of dholes in Debrigarh Wildlife Sanctuary. It tends to breed from mid-October to late December, and whelp in holes or ravines. It typically preys on antelopes, rodents, and hares. It usually hunts in pairs when targeting antelopes, with one wolf acting as a decoy while the other attacks from behind. The range of the Indian wolf overlaps with the golden jackal, sloth bear, leopard, brown bear, Asiatic lion and tiger.

Beringian wolf
A 2007 study of Canis dentition shows that in comparison with the modern gray wolf and the Pleistocene La Brea wolf, the Beringian wolf possessed large carnassial teeth and a short, broad palate relative to the size of its skull. The row length of the Beringian wolf’s premolars was longer, the P4 premolar (the upper carnassial) longer and wider, and the M1, M2, and m1 (the lower carnassial) molars longer than those found in the other two types of wolves. The Beringian wolf’s short, broad rostrum increased the force of a bite made with the canine teeth while strengthening the skull against the stresses caused by struggling prey. Today, the relatively deep jaws similar to those of the Beringian wolf can be found in the bone-cracking spotted hyena and in those canids that are adapted for taking large prey. Beringian wolves possessed a craniodental morphology that was more specialized than modern gray wolves and Rancho La Brea wolves for capturing, dismembering, and consuming the bones of very large megaherbivores, having evolved this way due to the presence of megafauna. Their stronger jaws and teeth indicate a hypercarnivorous lifestyle.

An accepted sign of domestication is the presence of tooth crowding, in which the orientation and alignment of the teeth are described as touching, overlapping or being rotated. A 2017 study found that 18% of Beringian wolf specimens exhibit tooth crowding compared with 9% for modern wolves and 5% for domestic dogs. These specimens predate the arrival of humans and therefore there is no possibility of cross-breeding with dogs. The study indicates that tooth crowding can be a natural occurrence in some wolf ecomorphs and cannot be used to differentiate ancient wolves from early dogs.

In 2016, a whole-genome DNA study proposed, based on the assumptions made, that all of the North American wolves and coyotes diverged from a common ancestor less than 6,000–117,000 years ago, including the coyote diverging from Eurasian wolf about 51,000 years ago (which matches other studies indicating that the extant wolf came into being around this time), the red wolf diverging from the coyote between 55,000–117,000 years ago, and the eastern wolf (Great Lakes region and Algonquin) wolf diverging from the coyote 27,000-32,000 years ago, and asserts that these do not qualify as an ancient divergences that justify them being considered unique species. The study also indicated that all North America wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly admixed with different proportions of gray wolf and coyote ancestry. The study found that coyote ancestry was highest in red wolves from th...

By late 2012, it was estimated that there were at least 75 wolves and four breeding pairs living in the recovery areas, with 27% of the population consisting of pups. Since 1998, 92 wolf deaths were recorded, with four occurring in 2012; these four were all due to illegal shootings. Releases have also been conducted in Mexico, and the first birth of a wild wolf litter in Mexico was reported in 2014. A study released by the U.S. Fish and Wildlife Service in February 2015 shows a minimum population of 109 wolves in 2014 in southwest New Mexico and southeast Arizona, a 31 percent increase from 2013. According to a survey done on the population of the Mexican wolf in Alpine, Arizona, the recovery of the species is being negatively impacted due to poaching. In an effort to fight the slowing recovery, GPS monitoring devices are being used to monitor the wolves. In 2016, 14 Mexican wolves were killed, making it the highest death count of any year since they were reintroduced into the w...

In Italy, the earliest remains of a wolf (Canis lupus) have been found in 1984 at the Middle Pleistocene site of La Polledrara di Cecanibbio, 20 km north-west of Rome in deposits dated 340-320 thousand years ago. The genetic analysis of Apennine wolves indicates that they went through a population decline of 100–1,000 fold between the past 4,700–23,800 years, which indicates genetic isolation south of the alps from other wolf populations for many thousands of years. In 1992, an examination of the mitochondrial DNA (mDNA) of 26 grey wolf populations worldwide revealed that the Italian wolf has a unique mitochondrial haplotype (a mutation) not shared by any other grey wolf population. Further tests on grey wolf mDNA revealed that, unlike several European grey wolf populations, Italian wolves do not share haplotypes with either other grey wolves or domestic dogs. In 2010, a study compared the mDNA haplotypes of 24 ancient wolf specimens from Western Europe dated between 44,000 and 1,2...
