I don't know if I am too late to respond, but I do have experience with a blind golden retriever that I can share.
My boss owns the blind golden, named Kali, and my sister and I house-sit for them while they are on vacation. Dog kennels are very stressful for Kali, as she has trouble interacting with other dogs and adapting to unknown surroundings. Kali was taught the words "careful" and "step" and can be off leash while you guide her with your voice. Their home is left as-is so she can navigate it without assistance--we can't leave things on the floor, like shoes. Her food and water dishes are never moved.
Kali is the sweetest dog you have ever met! She plays fetch (using a heavy, loud frisbee) and runs around and acts like a puppy, even though she is a senior dog. Caring for a blind dog is more work than a sighted one, but if you are willing to put in the time and effort, you may have a great companion. :)
