BAKERSFIELD, Calif. (WGNO) – A four year old boy, playing in his driveway is viciously and seemly randomly attacked by a neighbor’s dog.

What happened next was truly amazing.  And thanks to a home security system the whole thing is now on video.

The boy from Southwest Bakersfield was riding his bike when the dog sneaked around the back of an SUV, and began biting the boy.

Seconds later the family’s cat charged the dog, tackling it and chasing it off.

According to the boy’s father and Youtube poster, Roger Triantafilo,  his cat saved his son’s life. “My son is fine!”
