Ben`s last surgery

Hey guys. I hope you can help me save my dog. His name is Ben.,he is a shih tzu and he is 5 years old. He has been with me ever since i found him on a streets. He has a tumor and he lost vision on his eye. The doctors said if they remove it on time he will survive and probably live for another 2 or 3 years. The problem is that my paycheck is not near enough to cover the surgery.. I know there is good people out there so if you want to help thank you from me and Ben soo much..
