Otters are mysteriously attacking people and dogs in Alaska's largest city: "Unusual behaviors"

Residents of Alaska's largest city often contend with bears and moose, but state officials are warning of another wild animal that has been causing problems: river otters. The Alaska Department of Fish and Game says river otters have attacked people and pets in some of the city's most popular outdoor areas.

Officials are asking people to be extra careful when they are around rivers, creeks and lakes along the city's greenbelt.

Earlier this month, a 9-year-old boy was taken to an emergency room for a rabies shot after being bitten several times near a duck pond, the Anchorage Daily News reported.
