Dog Barks Back -- I'd Kill Myself for Forgiveness!

The Dog has only one excuse for dropping the N-word in a leaked phone message -- "I thought I was cool enough to be able to use" it.

Duane "Dog" Chapman was on "Hannity & Colmes" last night for his first interview since his son sold tapes of an N-word littered rant to the National Enquirer, and tried his best to defend himself against and apologize for the hate-filled tirade.

Chapman will continue his tour of contrition tonight, in an interview with Larry King.
