One kid sold him out, but another of Duane "Dog" Chapman's pups tells TMZ that the bounty hunter is not a racist.
TMZ got an exclusive interview with Dog's oldest son, Christopher -- one of Duane's litter of 11 -- who defends his dad regardless of the hate-filled rant. Dog Chapman came under fire last week after an N-word tirade was leaked to the National Enquirer by another son, Tucker -- who probably has a new first letter for his name.
For more of the interview with Christopher, watch TMZ TV tonight. Check local listings.
