Duane “Dog” Chapman, the star of “Dog the Bounty Hunter,” is under a doctor’s care after suffering what’s being called a heart emergency, TMZ reports. The news comes just months after the death of his wife, Beth Chapman, in June.

The report cites sources saying Chapman suffered a “possible heart attack,” adding that doctors are performing tests to determine the exact nature of the problem.

“Sources tell TMZ the reality TV star was taken to a hospital from his home in Colorado after feeling a pain in his chest,” the website reports. “They’re also trying to figure out if he will need a corrective surgery.”

The report adds: “Beth’s death has been incredibly hard on Dog — he broke down in tears at her Colorado memorial — who’s also been dealing with other forms of stress lately.

“His store was broken into last month — where crooks made off with some of Beth’s personal items — and Dog also nearly fell victim to a $430k check scam out of Dubai.”

Beth Chapman died June 26 of complications from cancer.
