In Toronto, a home invasion was thwarted when two dogs barked to alert their owners to the presence of an intruder.

Emily and Steve — who asked we only use their first names, for security reasons — were asleep at about 3 a.m. when a man in a blue sweatshirt, seen on security footage, kicked down their street-level front door.
