need help paying for vet bills

My boyfriend and I adopted our 3 month old puppy, Isabel, June 7, 2008. We were told the following Wednesday that one of the puppies in her litter had parvo and that she should be tested. She tested positive. Though she did recover, treatment cost over $1000 and while that put a financial strain on us, that wasn't the end: After recovering from the parvo, she came down with pneumonia and that treatment has cost us an additional $500+. We've taken out some loans but the problem is that my boyfriend and I are both students and are only working part-time to pay for other bills (car, our medical bills, school, etc.). If we don't get help, we'll be behind on other bills. The $200 only covers part of her vet visit on July 2 and medicine so we would love to see more donated to cover the other money we owe the vet!
We love our puppy and have tried to do what's best for her, please help!
