My oldest lab, Roscoe, has been blind for about 4 years. It was quick when his vision went because of a genetic disease common in labs.
He does amazingly well for not being able to see. At first, we noticed he would get a weird look in his eyes and stare at something in the air that we couldn't see. Then the treats became hard to catch, etc. We have had changes in our household surroundings and he has adapted to all of them. There are some things we know cannot be changed, like his back yard because he is so used to how things are and it's his haven.
There are times he is lost and disoriented. We touch his head to let him know we're there and that will usually get him to come toward us and to where he needs to be. Lately, it has taken longer for him to go down the back stairs and we often have to guide him down. He will not allow us to lead him in any way, not on leash or by his collar. But a touch and he'll go. The only thing that has changed about his quality of life is that he can't run anymore. But he sure can still find his tennis balls! We see more of a decline now, but he is 13 and I sometimes think it's more than the site loss and that dementia is setting in. But he is still happy and healthy!
