It's been a tough year for Duane 'Dog the Bounty Hunter' Chapman. America's favorite crime fighter suffered a 'heart emergency' over the weekend, and could require surgery in the near future. According to TMZ, Dog was taken to the hospital in Colorado after feeling pains in his chest. Doctors are doing tests, and trying to determine whether he actually had a heart attack, and if he is going to need the surgery.

The last couple of months have been a huge strain for the beloved bounty hunter. His wife Beth died from throat cancer on June 26th, and his new show 'Dog's Most Wanted' premiered on September 4th on the WGN Network. He has made hundreds of promotional appearances and interviews for the show, which no doubt added to his already stressful life. Check out the preview clip of the new show below, and keep a good thought for Dog and his family. Get well soon, DBH!
