Duane Chapman under doctor's care after medical incident

(CNN) — Duane "Dog" Chapman, star of WGN America's Dog's Most Wanted, is being monitored after a medical incident over the weekend, a representative for the TV star tells CNN.

"I can confirm Dog is under doctor's care and is resting comfortably," a representative for Chapman said in a statement, following reports he'd experienced a heart-related emergency. "Thank you for all of your well wishes — keep 'em coming."

When asked to clarify the nature of Chapman's medical issue, the representative did not immediately respond.

Chapman became known to television audiences via Dog the Bounty Hunter, a reality TV series that aired from 2004-2012. His late wife, Beth Chapman, starred alongside him on both his current and former series until her death in June.
