Doctors are baffled after a dog saved its owner from a heart attack with a hearth shaped patch on her flanks.
Piotr Wagner, 50, from Kazimierza Biskupiego, Poland, fell to the floor with severe chest pains while watching TV at home.
However, all the agony just disappeared when his two-year-old Jack Russell cross, Pearl, showed him her heart-shaped patch.
According to the Austrian Times, medics are now trying to find out the reasons of the pooch's healing powers.
"He certainly had a heart attack but it seems to have suddenly stopped and he is now healthy and back to normal," the Daily Express quoted a medic, as saying.
And Piotr is certainly proud of his beloved pet.
He said: "I want everyone to know about my big-hearted dog."
