Dog was officially diagnosed with a pulmonary embolism after experiencing severe chest pains (which was initially thought to be a heart attack) that landed him in the hospital.
The condition, which occurs when arteries in the heart fill up with blood, is dangerous and could result in an early death if not treated properly by doctors.
Dog the Bounty Hunter shared the news of his “life-threatening” condition on the Dr. Oz Show in an episode that will air this Monday, September 30.
