Tyler needs eye surgery

My dog Tyler needs to have his eye removed due to glaucoma. I got him when he was 8 weeks old. At the time I was deep in addiction. Tyler was always there for me, he was there during the worst times. He helped save my life by being there for me. Now that I am in recovery he helps me through my anxiety, depression, and ptsd. He means the world to me and I want to help him now and make the pain end. We live pay check to pay check and the cost is beyond our financial ability. Thanks in advance for anything you can do to help.
