Help Jack beat Parvovirus

We recently rescued Jack from Tijuana, Mexico and after today's vet visit, we come to find out that Jack has tested positive for parvovirus (dangerous virus especially in puppies) and has to be hospitalized for at least a week.
We are so heartbroken and are hoping for the best.
Jack was very energetic, playful, loving, curious and attentive upon arrival. By day two we started to notice diarrhea and vomit and some lethargy which we didn't think was normal and very dangerous for puppies. We immediately took Jack to the ER where he is currently staying for treatment.
We are hoping for the best and are devastated as we want the best life for him since dogs are very important and loved members of our family. Jack joins two older canine sisters Zuki and Lola who are also hoping for a speedy recovery.

We are asking for any financial help as it is not cheap to keep a pet overnight for several nights and not to mention the treatment as well. We want our little guy to beat the virus and live a long healthy life!

We would appreciate any help, thank you.
