Low Cost Veterinary Surgeon in Rochester NY

I am Brianna's grandmother. Her dog Snoopy was hit by a car about 1 1/2 years ago. His front leg was the most serious. At this time he can run around and is mostly himself, but has no use of the front leg. Is there a local vet who could do any operation for free or low cost? My granddaughter lives in the city of Rochester, New York.

Thank you for any help at all.
