Help with Lucky's medical expenses

I was on the way to the airport today for one of my final lessons before my commercial pilot checkride this coming week. As I approached the airport I saw something brown in the grass. I stopped to take a better look and sure enough it was a dog who seemed to have been hit by a car. Thank God he was still alive. At first I called animal control but then I realized they would put him down and I decided to scoop him up and take him the the Vet myself.
I named him Lucky. The bills are already mounting $1500.00 and we have only just begun.
Doctors believe he is about a year old and found that he has a broken hip and pelvis, as well as bleeding around his heart and lungs, which is requiring around the clock emergency veterinarian care.
I am not one to ask for personal favors but I know that God sent him to me, and I want to give him a fighting chance. I will not let them put him down simply because of money, if he can have a good life.. Please help, any donation would be greatly appreciated! Thank you :)

***UPDATE: it is with sad news I inform you that Lucky passed away at 5:57am. His little body couldn't withstand all the trauma. He will be cremated and taken home with me. Any money raised over his medical expenses will be donated to a shelter.**
