Help Arrow the Puppy !

My roomie Nancy is the sweetest ever and her little puppy wiggled through the gate and was hit by a car this evening. One of her legs was crushed and could be facing amputation . She had to go to the emergency vet tonight for pain management and will be seeing another vet for surgery tomorrow. Animal lovers ... you know how hard it is to see your baby hurt!(and how expensive the emergency vet is ) If you can donate anything to help Arrow the crazy lil spunky puppy keep going and living life, it would be so appreciated.
