Save Koko from Parvo

Any On Wednesday March 4th 2015 I bought the cutest most gentle and cuddly little puppy from a pet store. The pet store owner assured me this dog had received her vaccines and was completely healthy and she definitely looked the part up until the day I picked her up. She hadn't ate and was a little mopey, which I just assumed was the stress of moving into a new home and being held captive in a cage at the store. She appeared to be a little bit okay up until Friday morning when she woke me up getting sick profusely.. Immediately I brought her to the emergency animal hospital on walker road and she was tested positive for parvovirus, a seriously dangerous virus that has an extremely low survival rate if not caught early enough (a virus she was supposed to be protected from by her supposed "vaccines").My 8 week old little Koko is fighting for her life on an IV and a feeding tube, and now is also receiving plasma tranfusions. The pet store owner is being very uncooperative and made it CLEAR that he does not want to take back the dog (which is not an option to me regardless) or pay the cost of HALF the vet bills, clearly he doesn't want to get the puppies in his care the healthcare they need to survive. My heart aches for my little 2.5 pound innocent puppy who has already had such a difficult life. Koko is in desperate need of as much medical attention as can be provided to her which has already cost me about $3000 for 3 days of care and is continuing to go up. With her being on an IV, feeding tube, recieving plasma, staying in the extensive care unit of the animal hospital, daily doses of 3 anitbiotics, antivirals, pain killers, anti nausea, stomach lining meds, and many other medications the cost per day is about $1000.  I fear that if I cannot keep up with the vet payments my little puppy will have to be euthanized and that breaks my heart. I am doing everything I possibly can to make sure she fights through this but the financial aspect is difficult as I am a university student with not a whole lot of spare funds. I am moving out of my apartment, maxing out my credit card, and putting every spare cent i have into her treatment costs. Any donations are so greatly appreciated, I just want my baby back home. Any extra money I receive will be donated to local humane societies and animal rescues to save other puppies like Koko.
