It was a split second attack... a dog versus a young teenage boy.

The 14 year old was walking home from school when a neighborhood dog... leaped a fence and attacked him.

One of those good Samaritans..was 54 year old Wayne Markwith...who says he was leaving his mother's house when he saw the animal attacking 14 year old Emanuel Valentin on Wednesday. He stopped the car and charged the dog screaming and says that temporarily distracted him...giving the boy enough time to get into another passerby car.

Every day...14 year old Emanuel Valentin walks home from Belleview Middle school...but yesterday he was met by a terrifying surprise.

Luckily a good Samaritan...stopped to help Valentin...and someone else grabbed a nearby officer.

The dog...which took a shot to the chest then limped away...and soon died and even though..Valentin had to get stitches to his leg...he and his mother beth are just grateful it wasn't worse.

Wayne Markwith... Who initially stopped to help... says he doesn't consider himself a hero... just someone who was raised to help people in need.

According to police the owner of the dog...had recently been given the dog...and was trying to find it a new home. He won't be charged by deputies in Marion county.
