Help dogs raise medical expenses

I came across a dog on the way from get off work and unknowingly followed it home. It looked good, so I decided to stay and let it have a home. After a few days when I went home, I found something was wrong. I took it to the hospital to check that it turned out to be sick. Abandoned by my master, my financial condition is not good, and I am unable to treat it.

Hope there are good-hearted people to save it.
