Forty years ago, an angry and rebellious Duane “Dog” Chapman dropped out of school in the seventh grade never to return. Thirty years ago this summer, Dog began a five year sentence for his involvement in a murder.

After serving nineteen months in a notorious Texas prison, Dog emerged a changed man – determined to turn his life around and to help others along the way.

Looking back on the moments that helped create the word’s most famous bounty hunter, A&E presents "A Man Called Dog," a one-hour special that travels through the past with Dog, his wife Beth and his posse, as the legendary bounty hunter makes a present day journey through his origins in Colorado and Texas to reunite with old friends and mentors to re-live significant moments from his past. The special premieres Tuesday, August 14, at 9:00PM ET/PT.

Dog’s life has always been extraordinary. From his wild outlaw-biker days to his rehabilitation in a Texas prison to his long journey to become the world’s greatest bounty hunter. This one-hour special promises to be one of the most compelling and moving hours of Dog The Bounty Hunter as Dog finally comes to make peace with his troubled past, including a trip to his father’s grave which reveals a side of Dog fans have never seen before.

"A Man Called Dog" is the cornerstone programming event of "Dog Days Of Summer," which includes a viewers’ choice marathon on Monday, August 13 from 9PM – 11PM and an all day Dog the Bounty Hunter marathon on Tuesday, August 14, from 8:00AM – 9:00PM as well as "Dog The Bounty Hunter" premieres throughout the month of August.
