Dogs
Man's best friend is also the mammal most likely to kill him. Of the roughly 25,000 people killed by dogs each year, the majority die from rabies.
Over 90 percent of rabies infections in humans worldwide are caused by dog bites, though that number is much lower in the west where rabies has been well contained in canine populations and skunks and bats are more likely than dogs to infect people.
While it is very rare for someone in North America or Western Europe to die of rabies, an estimated 20,000 people die in India each year from the disease due primarily to the prevalence of stray dogs.
