Person for the blind dog

Bruno's eyesight has been noticeably deteriorating over the past few months. He often walks into things and when he's looking for me, won't notice me unless I make a big movement (like those movement sensitive lights in offices).
The vet said he's practically blind. It's worse than I'd appreciated because he gets used to being at home. Of course, dogs have strong sense of smell so it's not as dramatic as it is for a person. But I need to make sure I give him lots of physical contact.
