I work with a shelter and we had a dog that was blind. I thought once you're blind, nothing else can happen to the eye but I was wrong. The eye started bulging and then the other. They both had to be removed (sounds terrible but she couldn't see anyway). A few weeks later, she was like a puppy. She must have been in so much pain from whatever was going on. It cost alot of money, but you can't put a price on a life. The thing you have to pay attention to is the demeanor of the dog. Does he appear happy or is he mopey all the time. Does he seem like he's in pain. Pay attention to these things and you'll know if you made the right decision but you have to wait until he recovers to see how his attitude and personality is after all this. The poor baby has been through alot. I'm so proud to hear about people like you who would spend anything to save them. I've had to get out an equity loan for mine and I don't regret one minute of it. Kudos to you! You've got a seat in heaven!
