On the side of a dirty trash can, a weak dog lying helplessly, can only occasionally pick up food left in a barrel and drink the dirty water from a puddle next to it to keep itself alive.

See here. Maybe everyone thought it was a stray dog, but it wasn't.
The poor dog actually has a master and the neighbors know the dog. The dog's life was not so bad, but it was the recent illness that led to a catastrophic change.

This little white dog has been with the owner for years, and it was also taken home by the master. The dog's owner is usually good for it, but in the master's subconscious, the dog is just a pet that can feed without spending money.
If it was necessary to pay for a dog's medical treatment, the owner would be completely unacceptable.
During the previous period, the dog threw up several times at his house for unknown reasons. When the master saw it, he did not mean to take it to the pet hospital for treatment, because he did not want to spend the money.
As a result, the dog had not only not been cured, but had also increased its condition; it had been vomiting at home for seven days, making it dirty.
And that's why the strange master finally washed the dog out. That's why we saw the dog looking for food alone and living in the scene next to the trash can.
The only good thing is that the neighbors know what happened to the dog, and they feel sorry for it and feed it regularly.
But even so, the dog's condition is getting worse every day, and it's walking, and it's losing light and despair.
Fortunately, a volunteer from a rescue centre learned about the dog and found it.
When the volunteers came to the dog, the dog had already lost its ability to resist, and it was well-behaved and carried away quietly.
Because the dog was so depressed, the volunteer immediately took the dog to the pet hospital. When the doctor examined his body, he gave the dog a notice that he was in danger.
The reason is that anemia, kidney failure, dehydration, hypothermia and all kinds of conditions in the dog ' s body are at risk of death at any time.

Fortunately, even though the doctor said the dog was not likely to be cured, the volunteer insisted that the dog be treated.
In the end, miracles occurred and, with volunteers, the dog's body slowly recovered and survived a dangerous period.
Today, this once-abandoned dog has completely recovered its original beauty, and its already thin body is beginning to grow stronger.
Most importantly, a lot of good people love this dog, and have an intention to adopt it.
After these days, this rescued puppy will be adopted by a gentle man to start over its happy dog.
