Callisto's Vet Bills

This is my baby Callisto, she is a 6 month old lab mix and she has my whole heart. She has been exceptionally healthy and if you've ever met her, you know she's an absolute sweetheart. Last week on Saturday she was acting strange, I called our vet. The vet told me to go to the hospital, so at 1pm in the afternoon I was rushing my sick puppy to the emergency room. We waited 7 hours until they discovered through bloodwork that her kidneys weren't working properly. They treated her and she responded initially. She then suddenly became worse, requiring more testing. If you want all the medical details I'm happy to explain, just shoot me a message! She is now finally home after 6 days in Hospital.
Although I would do anything for this little girl, I need to ask for help here because I can't cover her vet bills. Her total is at 5,240$. 
Any and all help is truly appreciated by me and Callie!
