Puppies with parvo need treatment!

2 puppies of 5 got parvo, the treatment is €40 per day, and they need at least 14 days of treatment... the rescuer is overwhelmed by now. The vet bills are growing each day... the puppies had to be separated and unfortunately there is a huge chance the other 3 will get it too. Hoping the puppies are gonna pull through. Thank you people!
