> Does he wander around the house alright without bumping into things?
Don't know about Marianne, but I have a positive experience of a blind dog. I had a Toy Poodle years ago that had to have one eye removed, and the vet said that sight was going in the remaining eye. I started talking to him while out on walks, using the word careful when we reached a pavement or obstacle. Once blind he coped admirably, and I could actually go running in fields with him loose, as long as I kept talking to him, so he could stay close. He trusted me completely, and we learned to get about quite well.
He already knew the layout of the house and garden, and I just never moved the furniture, so assumed he got about from memory. Then the upheaval of a house move came, and friends said it was cruel to move him. Not so!

He moved to a house with a very much huger expanse of garden, and I couldn't believe it when he made his way round the perimeter, keeping close to the sides, and sniffing as he went. He did just find, and lived to a ripe old age. It can be done!
