However, black bear attacks on humans are highly unusual and occur mainly when a bear feels her cubs are threatened, according to the Department of Natural Resources. People who are attacked by black bears are encouraged to stand their ground and not back away or play dead.
The Michigan Department of Natural Resources is actively searching for the black bear that attacked Abby by setting bear traps and has plans to euthanize the bear after it is caught.
In spite of the attack, Dave Wetherall told WZZM-TV his granddaughter wasn't afraid of getting back on the trail.
"She's a hunter, she likes the woods, she's just a very tough, kind person," Wetherall said.
