My puppy Bacon is sick.

A week ago while having breakfast with my kids and our puppy Bacon, he started to throw up and show sign's of not feeling well. The rest of the day he didn't have much interest in anything so he just layed in his bed and slept. Hoping he would sleep it off and feel better the next morning we let him sleep. The next morning I wake up and go check on him and his is laying on his side in his throw up and urine... panicked I pick him up and rush to the shower and clean him off and call the vet and rush him over to them. They come out and test him for parvo and intestinal parasites and he was negative for both so they rushed him inside and too him straight to the back to start helping him. Not having any idea what could have happened they start asking me could he have got in to this or around any other animals. He is our only pet and is an inside pet 95% of the time We have no neighbor's. Bacon has now been the the best care almost a week and I do not know how I am going to be able to pay for his medical bills. I dont have the best paying job and had no money that I was able to set aside for emergencies. I am asking for help to be able to pay his medical bills and get our Bacon back home to us as soon as possible. I do not do social media so I have no Facebook but I can send pictures and prove that Bacon and us are real.
