Pandas surgery

My puppy panda was hit by a car and left for dead on Friday night. She was rushed to the emergency animal hospital and after doing some xrays they found out her pelvis is fractured in 3 different places, basically leaving it in pieces. My poor baby can’t even stand up and is basically waiting for a specialty surgeon to come to mission animal hospital to do a surgery. They are estimating the surgery to be close to 3,000$ and will do payment plans with a required 50% down payment. I have been denied for every pet credit card program and grant program. I feel defeated and I just want to help my sweet puppy. if there is anyone who could help in any way possible I’d be forever grateful.
