Little Jewel doesn’t stop there, chasing the bears until one of them is forced to quickly clamber over a fence and flee the property.

Owner David Hernandez said he couldn’t believe Jewel’s reaction to the bears.

“[It] blew me away. I couldn’t believe it … she turned into a wolverine,” he told WSBT-TV news.

Mr Hernandez has set up the security camera after bears started damaging his property.

Bear sightings are common in Monrovia, while coyotes and mountain lions also roam the area.
