My dog got hit by a car run over dog

Two weeks ago my dog was run over.
I was taking the dog for a walk on a sidewalk of the city, when at a crossroad a car hit crashed to the dog.
I had him on with his leash and as it is 5 meters long while I was at the other sidewalk of the crossroad he was just at the middle, I suppose the driver didn't see him and when I finish crossing she went on until heard the dog's scream.
The rude driver didn't get out of the car nor asked me about the dog and when we where aside she fled.
Fortunately I could see the plate and immediately phoned the police, then I told the policeman what had happened and I went to the vet.
The dog was had to have an operation ed on of a his leg the next morning and now he can't walk properly, he is walking with three legs, and when he get got better over he had to have phisical do therapy. 

While I reported the car driver and I hope that  she pays the vet and the cost of therapy
