It all started when she heard her three dogs barking, but thought they were just chasing a squirrel or bird, as dogs do.

After her calls for them to settle down didn't quiet them, Hailey darted outside to calm the commotion – only to see a bear pawing away at her fur babies, and eventually snag one in its mouth.

Without thinking, the teen ran over to the bear and pushed it off the fence while managing to snatch her beloved pup from its grip.
