ACF, I'm sorry to hear about your baby, but please know a blind dog can lead a rather normal and happy life. My BFF used to have a huge Irish setter - seriously, like a small pony - who went blind, and he did just fine. She was renting a room in a large home, and within weeks he got along so well, it was hard to believe he couldn't see. I called to ask her about the scent on the doors, and she said she never did that, but would walk him in and out the pet door until he got more comfortable. Honestly, he maneuvered around beautifully. I wish you luck and please keep us posted on how he's doing.
