Help save my baby boys from parvo

We decided to move to a new place where my dogs would be able to have their own yard to play and run around in shortly after that my 4 month old puppy started acting sick and not moving or eating we brought him to cheat lake veterinary clinic in Morgantown we would told his treatment to be hospitalized was $8,000 we didn’t have all that to keep him there so we got the treatment for at home which was $900. My baby has not been improving over the 4 days and hasn’t eaten anything in 3 days we’ve been syringe feeding him and doing everything we can. We called back to see what further we can do so he isn’t suffering they told us we need to hospitalize him but we need $1,000 upfront before starting the $7,000 in payments. That morning we noticed our 1 year Chihuahua throwing up and not eating or moving we rushed him to the vet and was told he needed to be hospitalized due to him being so small they don’t know if he will make it without more treatment that is expensive. He is at hill side vet fighting for his life just like my other baby fighting for his life at home we are doing everything we can for him and trying everything to get him in hospitalized asap. Anything will be very much appreciated to help save my baby boys from this horrible sickness.
