Help Mishka beat Parvo

We've never done this before, but our family would truly appreciate your help. 

Mishka is our 13 week-old Caucasian Shepherd puppy. He is the sweetest dog we have ever owned, and our son absolutely loves him. 

We thought we had done everything right. He had his first three rounds of shots exactly on schedule, and we avoided bringing him into public until the vet suggested it was safe. Despite this, he became deathly ill and was diagnosed with Parvo seven days ago  

As I write this, he's currently in his second hospital stay with our emergency vet. The prognosis is still positive as long as we keep him hospitalized until he recovers. However, we are now over $6000 into his care this week, and we don't know what else he may need. 

We are committed to bringing Mishka home safe for our son and letting him live a long, happy life. Anything you can spare would help a lot in that goal. 

Thank you!
