Can You Help Save My Puppy

My name is Eric Godfirnon and I'm hoping some of you caring animal lovers can help me save the life of my 9 week old mini schnauzer Zero? I bought this little guy a week ago but unfortunately the 'breeder' sold him to me with parvo which I was unaware of until I ended up having to rush him to a vet hospital last Wednesday. What started as potentially one night in the hospital and $1300, turned into 2 additional nights after he tested positive for parvo and an additional $2000 in expenses so they could run tests, treat the parvo, and work on getting him strong enough to eat. This morning I received the latest update and unfortunately it wasn't great news. While he's started to hold his fluids, unfortunately he still isn't eating. Because he isn't eating his protein levels are dangerously low.  I was presented with a choice nobody wants to make. Save an additional $4200 and put him to sleep or do the right thing and try to save his life.  As I write this, my vet bill is currently sitting at $7500 because I did the right thing and opted to try and save him.  I'm prepare to deal with this myself but any help I could get would be greatly appreciated   I don't think anyone expects to shell out upwards of $8000 the first week they own a pet but unfortunately that's what I'm dealing with.  Thanks in advance to anyone that can help or share this. Blessings, Eric
