Rescue injured stray dogs

Everybody is good, the day before yesterday I in the library next to the bushes picked up a very small dogs, like a newborn puppy, lying on the grass motionless, I walked over and picked it up and found it still breathing, just hasn't been opened his eyes, it is very thin, like a few days without eating, it's nose has had a running nose and I think it was ill,Then I sent it to the pet hospital, where it was diagnosed as suffering from parvovirus, which required injection for surgery and hospitalization. The doctor said that the disease was very difficult to cure, but I still hoped against hope that the dog could be saved. Therefore, I raised the cost of the operation here, hoping that everyone could help this poor stray dog.
