Save Comet O'Toole

I rescued this puppy from an unfit home on Saturday, and I was told he was a healthy puppy. I watched as his health declined rapidly over the past two days, and immediately took him to the vet. He tested positive for parvovirus, and is now hospitalized for around $5,000 per day. We can afford to hospitalize him for 24 hours, and then we are forced to do outpatient care for him at this point due to insane vet costs. Since he is only 8 weeks old and barely 2 pounds, he needs all the help he can get to survive. I've only had him for a short amount of time, but he is the sweetest dog I've ever met who truly loves everyone he encounters and life altogether. He deserves to live a long and happy life, and I want to give him the best shot of survival by providing a few extra days of vet service. I need the funds ASAP, and would be grateful for any type of help.
