Family cat saves child from stray dog attack

(KTVI) – A vicious attack by a stray dog was thwarted by an unlikely hero — a cat.

The video was posted to YouTube on Wednesday. The user Roger Triantafilo caught the incident on surveillance cameras.

The video shows Triantafilo’s son in the driveway on a bike when a stray dog grabs the small child by the leg and pulls him off the bike.

But then out of no where, the family’s cat lunges at the dog and chased him away from the child.
