hi i am sorry you are having to go through this it is a very worrying time, i have nursed a dog through parvo with the help of my vet to start with but decided to bring her home on a drip as they did not think she would make it through the night, i am very glad to say that she is still here with me now and if you want any help or advice about how i managed please feel free to pm me, but please vet help and med are a must.
good luck XXXXXX
