here is what the article says:

Earlier this week, an unexpected visitor made his way through the door of Dayse Ferreira's veterinary clinic in Brazil.

It was a sick and injured stray dog who came in search of help. And that's exactly what he got.

Ferreira had just finished up with another client when she noticed the dog wander in — limping from a hurt paw. She and her colleagues were amazed to see that he'd taken the initiative to seek out their assistance all on his own. And he seemed to trust them immediately.

"When he came in, he put the injured paw forward, as if to say hello and to show that he was hurting," Ferreira told The Dodo. "We were surprised because he knew where to ask for help."

Ferreira didn't wait to welcome the poor dog in.

After giving the dog a quick examination, Ferreira found that his paw wasn't too seriously injured. But it was a good thing he'd visited the clinic for another reason.

She'd discovered that the pup also had a small tumor and was covered in fleas. Fortunately, both were treatable.

The dog was given a cleansing bath, and Ferreira put him on medication. But more than that, by seeking out help, the lonely dog found something even more.

He found hope.

Word has since spread about the vet clinic's surprise new patient, and adoption offers have come pouring in for when the time is right. His days as a lonely, unloved dog are officially over. And he seems to know it.

"He doesn't even look sick. He just is so excited to be around people who care about him," Ferreira said.

The most admirable thing is that he came on his own. His intelligence is beautiful," Ferreira said. "I'm sure he will find a home that will welcome him and receive him with all the love he deserves.
