If you’ve read about the puppy who saved his owner from a rattlesnake, or the dog who waits at a train station for 12 hours a day for his human to come home from work, you know that the love of these magical creatures knows no bounds.

However, if you have any doubts, allows us to direct your attention to a touching photo recently shared on Facebook by Cris Mamprim, a healthcare worker at Hospital Regional Alto Vale in Brazil.

At around 3 a.m. last Sunday, the hospital admitted a homeless man named César, who needed to be treated for some medical issues. When the hospital staff looked at the door, they saw a group of faithful dogs, anxiously standing at the periphery to make sure their human was all right.

Even though César is homeless, he still cares for the dogs, and that care is infinitely reciprocated, because there’s no such thing as unrequited love in the world of a dog. Mamprim wrote on Facebook:

“A simple person, without luxury, who depends on help to overcome the hunger, the cold, the pain, the evils of the world, has by his side the best companions, and the exchange is reciprocal. Exchange of love, affection, warmth, understanding. A person who confessed to us that he sometimes goes hungry in order to feed them. I don’t know what his life is like, because he’s on the street, and I don’t even want to know and judge him, but I admire the respect and love he has for [his dogs]. Seeing them like this, waiting on the door, just shows how loved and cared for they are.”

The staff invited the dogs inside, and fed both César and his canine crew. An hour later, he was discharged from the hospital, and while there’s no telling what the rest of his life will be like, you can be sure the dogs will be by his side. And for another amazing story about canines, read about this patient dog who went viral for politely obeying a cafe’s “no dogs allowed” rules.
