WEST MILFORD: Video of the dog chasing a black bear from his backyard goes viral in social media.

Mark Stinziano tells WABC-TV his home security camera captured what happened Tuesday night when the bruin decided to snack on the bird feeder behind his West Milford home.

The video shows the bear pulling down the bird feeder when the neighbor’s dog, Riley, races into the yard. Riley slammed into the startled bear, which scrambled to escape.

Riley’s owner, Alan Tlusty, says his dog always chases the bear whenever he sees him in the yard.

Stinziano says Riley also checks on his children when they’re in the pool. (Agencies)
