Save Azura: Urgent Surgery Needed After car accident

My name is vanessa and this is our family dog azura, shes just turned 4 and escaped from our yard to go find my dad and brother who left on a trip. We had been searching for her immediately for over two hours with no luck. Apparently on her spontaneous adventure she was suddenly hit by a roustabout truck that didnt stop. This was seen by a few witnesses who called the pound and they had gotten her when we were searching without us knowing how far she had ran, she didnt have a history of running out like that but we called early in the morning to see if they found her and they did. They told us she was hit and wasnt doing well. They didnt have a vet and we went immediately to get her. Her hip has been dislocated and her knee has a pretty severe case of roadrash. We cant afford the surgery to fix it after the first round of vet bills to get her xrayed and painpills, antibiotics, and anti-inflammatory pills. We are doing are best to make the money up but not as quickly as we can. Any help would really be appreciated!
