American reality TV star Dog the Bounty Hunter - real name Duane Chapman - has been rushed to hospital with a 'heart emergency', TMZ has reported. The news comes just three months after he lost his wife and on-screen partner Beth Chapman, at the age of 51 to throat cancer.

Per the Daily Mail, the TV star, 66, was rushed to a Colorado hospital after experiencing chest pains. A source close to Dog told TMZ that doctors haven't pinpointed exactly what happened, but they believe it was a possible heart attack.

Doctors are now performing tests to determine the precise nature of the problem, while simultaneously trying to figure out whether or not he will need to undergo corrective surgery.

Per the Mirror, a representative for Dog The Bounty Hunter told the UK publication: "I can confirm Dog is under doctor's care and is resting comfortably. Thank you for all of your well wishes - keep 'em coming."

Since news of Dog's hospitalization came out, his daughter Bonnie has posted a heartfelt message of support on Instagram. Posting an old photograph showing a young Bonnie sitting on her dad's lap alongside late mom Beth and big sister Cecily, the 20-year-old wrote: "Love you, pops."

Comments from fans and wellwishers quickly flooded in, extending their support to the family:

Last month, TMZ reported how Dog's Colorado store was burglarized, as crooks made off with late wife Beth's personal bounty hunting gear. A rep for the family said that "priceless personal belongings of our beloved Beth, including tributes to her kindly left by our amazing fans" were taken from the property.

Dog has also been making several promotional this past week in preparation for the premiere of his new show Dog's Most Wanted. Speaking again to TMZ earlier this month, Dog revealed how he has not yet seen a final edit for the show as it is too difficult for him to see footage of late wife Beth.
