Saving a potential life long buddy

This is Milo. 3 months old. A service dog in training. Milo is a very very sick boy right now. After taking him to the vet and starting treatment, we were told that if we don't have the full $1,500 with us on his discharge day we will lose him. Meaning they will keep him and adpot him out to a new family. Milo is our whole world. Not only has he started to alert us for medical issues between my son, Zane and his girlfriend, Skyla. They both have had a Bone Marrow Transplant or BMT and is both currently fighting for their lives. Having their service dogs with them gives them the independence they need. Being sick is hard but having a service dog makes life much easier. But now that Milo has been tested positive for Parvo, we are all on the edge. Milo was actually scheduled to have his vaccines and neutered surgery for this coming week because vets have told us he couldn't be vaccinated or fixed until age of 12 weeks. Knowing the knowledge now that, that is incorrect, we can't stop blaming ourselves. At this point in time we just dont wanna lose our baby boy. Please if you can help us in any way possible. Weather it be donating or even sharing this gofundme link. Please help us. We are doing everything we can to bring him home. WE NEED HIM HOME.
