Duane "Dog" Chapman was hospitalized for what appeared to be a heart-related emergency over the weekend, multiple reports confirm.

TMZ reports that Chapman, also known as "Dog the Bounty Hunter," experienced chest pains and was taken to a hospital for treatment. CNN confirmed that Chapman was being monitored after a "medical incident" over the weekend.

A representative for Chapman said Monday on Facebook, "I can confirm Dog is under doctor's care and is resting comfortably. Thank you for all of your well wishes- keep 'em coming.”

TMZ says doctors performed tests and feared it may have been a heart attack, but now say his health issue is believed to be related to stress and blood pressure.

A source reportedly told TMZ that he was released from the hospital Monday night.

In June, his wife Beth Chapman passed away at age 51 after battling cancer. The two starred in the reality TV series "Dog the Bounty Hunter" on A&E.
