Stray Pyranees needs surgery

My friend witnessed a dog get hit by a car in front of his work yesterday. He took her to the vet and had xrays done. She has a broken pelvis.  The estimate for the surgery is $1631. We've named her Baby and she is NOT microchipped. My friend is paying the bill up till tomorrow morning which is over $300. I gave the vet permission to do surgery tomorrow otherwise she'll have to wait till the end of next week. I help ALOT  of dogs out of my own pocket but this time I'm asking for help. If you can donate ANYTHING it will be APPRECIATED!! I will probably pick her up Mon or Tues of next week but I have to pay the FULL AMOUNT. This vet does not give any rescue discounts.  Thank you sooo much!
