This, coupled with their size and strength, makes rabid wolves perhaps the most dangerous of rabid animals. [195] Bites from rabid wolves are 15 times more dangerous than those of rabid dogs. [198] Rabid wolves usually act alone, travelling large distances and often biting large numbers of people and domestic animals.
Wolves in Slovakia, Ukraine, and Croatia may disperse into Hungary, where the lack of cover hinders the buildup of an autonomous population. Although wolves have special status in Hungary, they may be hunted with a year-round permit if they cause problems. [26] Romania has a large population of wolves, numbering 2500 animals.
Large mammals develop at an absolute slower rate compared to small mammals. Thus, the large mammal tend have longer gestation periods than small mammal as they tend to produce larger neonate. [18] Large mammals require a longer period of time to attain any proportion of adult mass compared to small mammals. [19]
The egg is not retained in the body for most of the period of development of the embryo within the egg, which is the main distinction between oviparity and ovoviviparity. [1] Oviparity occurs in all birds, most reptiles, some fishes, and most arthropods. Among mammals, monotremes (four species of echidna, and the platypus) are uniquely oviparous.
Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 – 135 lbs).

A number of incidents involving aggressive wolves have occurred in Alert, Nunavut, where the wolves have lived in close proximity to the local weather station for decades and became habituated to humans. One of these wolves attacked 3 people, was shot, and tested positive for rabies. [20] Arctic wolf feeding on muskox carcass in Ellesmere Island
The cranial length of the adult Arabian wolf measures on average 200.8 mm (0.659 ft), which is smaller than most wolves. [15] Along with the Indian wolf, it is probably smaller than other wolves to help it adapt to life in a hot, dry climate. [16] This is an example of Bergmann's rule, where
Since the discovery in 1963 that eastern wolves answered human imitations of their howls, Algonquin Provincial Park began its Public Wolf Howls attraction, [59] where as many as 2,500 visitors are led on expeditions into areas where eastern wolves were sighted the night before and listen to them answering the park staff's imitation howls.
