The good news first: Gray Wolves prefer to steer clear of people, choosing remote areas in which to live and avoiding human contact as much as possible. The bad news? If paths should cross, fatal attacks can and do occur.
Native to North America and Eurasia, the Gray Wolf is a merciless and powerful beast that becomes aggressive during times of confrontation. In countries such as Russia, Belarus and Ukraine, encounters are not uncommon.
Gray Wolves are natural hunters that travel in large packs, their senses sharp and their skills honed. Weighing up to 45 kg, tackling larger prey — people included — holds no fears for these natural-born killers. The head and face are targeted first, with savage bites designed to debilitate and inflict maximum damage. Their victims limp and lifeless, Gray Wolves drag the kill away, ready to enjoy the spoils and consume a well-earned meal.
A worldwide 2002 study by the Norwegian Institute of Nature Research showed that 90% of victims of predatory attacks were children under the age of 18, especially under the age of 10. In the rare cases where adults were killed, the victims were almost always women (wikipedia).
Historically, children are more vulnerable to wolves as they were more likely to enter forests unattended to pick berries and mushrooms, as well as sometimes mistaking wolves for dogs. While these practices have largely died out in Europe, they are still the case in India, where numerous attacks have been recorded in recent decades.
