He is 7.5 and his eyes have never been that good. When we got him, I was told chocolate labs were prone to eye, ear and/or skin issues. He has never seen movement the way I thought he should and 2 years ago I noticed he had trouble seeing at night. Now he is to the point he would be considered legally blind if he were a human. The vet said she thought his lenses had moved. The consult with a veterinary optometrist was a 4 hour drive, $500 just confirm and surgery could be in excess of $4K. We don't have that kind of money to put in a dog that has lived out 75% of his life. I love him, but I've had dogs my whole life and shit happens to them, then they die. Just part of the process. He'll live out his life in comfort and when it looks like his eyes are gone to the point of making his life not worth living, I'll put him down.
One thing about him though, his nose is incredible. I came home Friday and there were some doves in the pines out back. I busted one while he was in the garage. He comes flying out of the garage when the gun went off and starts working a Z pattern all over the yard. A good gust of wind kicked the scent his way and he was on that bird in short order. He may not be able to see, but his nose more than makes up for it when it comes to retrieves.
