2 month old puppy ‼️HELP‼️

Does anyone know any free puppy exams, besides vca! my puppy got Parvo (sorry if I misspelled it) 2 weeks ago so we had to inject iv for a week. Long story short lady fucked up and told us to give her these treatments on her neck only, which IS A BIG NO we should of done it ANYWHERE with extra skin, so she got abscess all over her neck and now her private area. She tested negative for parvo now, but more things keep coming up everytime she sends to get better! Any advice or free puppy exams anyone knows about? Please help!! Also if anyone knows how to get extra cash! I cannot afford to keep going to these expensive vets right now!!! Please please help
