Theory:

     There is a homeless man in Rio do Sul in south Brazil who often sacrifices his own food to feed the stray dogs around him. One time he suddenly required emergency treatment, his kindness came back to him like a boomerang, for the faithful dogs he had been feeding made sure he wasn’t alone.
 
     The dogs’ incredible loyalty was witnessed by nurse Cris Mamprim and her colleagues. The homeless man, known as César, arrived at the emergency room of the hospital at about 3 A.M. to seek treatment and medication for a pre-existing health condition he had been battling. It was his first time at the hospital for treatment, as he normally goes to another health facility in town. Thus, Mamprim and her colleagues did not know about César’s condition, nor his background.
Explanation:
 
This is a real incident that happened in a place called Rio do Sul, in South Brazil.
 
A man was living on the streets in Rio do Sul. He was a homeless person as he did not have any money to buy himself food or shelter.

But whatever food he got, he sacrificed to feed the stray dogs around him. One day he fell sick, and he required emergency treatment. His faithful dogs came to his rescue and did not leave him alone. The kindness that he showed came back to him like a boomerang. It was the dogs' turn to show him their kindness. Boomerang is a curved flat piece of wood that can be thrown so that it will return to the thrower, traditionally used as a hunting weapon.

Boomerang, returns to the thrower!
 
This unbelievable story of the dogs and their homeless master was seen and experienced by nurse Cris Mamprim and her co-workers. The homeless man's name was César. He came to the emergency room of the hospital at 3:00 AM that morning, to get treated for an already prevailing health problem that he had been suffering. César normally went to the health facility (clinic) in town, but this was his first time at a hospital. So the hospital staff and Mamprim did not know about César's health problem or his history.
