Romeo’s fight against Parvo Virus

This is my puppy Romeo! He’s an Australian Shepherd, only 9 weeks old. We just picked him up 2 days ago from a private seller online. The seller didn’t inform me of his puking and lack of appetite when we picked him up and he has been sick since. He hasn't eaten a thing and has been consistently vomiting for the past few days. I’ve spent money on different foods and antibiotics but he was still sick. Romeo is now hospitalized because he tested positive for canine parvovirus. Parvo is a viral infection with no real cure, just continuous treatments in hopes that the puppy overcomes the virus. The cost of his medical bill at most can come up to around $5400. I am asking for help with the medical cost because I am a student and I really don’t have the means to pay this expense. I only want my first dog to be happy and healthy and give him a chance at life because he deserves it. I really hope with some help I can reach a goal of $4000 or $4500 so my handsome boy can get a chance at a good life. Hopes and prayers that he gets better and if anyone can help in any way! Thank you ❤️
