I found the picture of Shane's eyes
SouthernGirl, i knew from previous posts that you are on budget and i can understand about not having money. I know you and your mom are helping out multiple dogs there, too. Almost all the vets i know did not go into the field as an attempt to get rich, but to help animals...........and most vets i know are generally kind loving ppl, imo.
As Anneke said, it is most likely something called nuclear or lenticular sclerosis. Basically it's an age related change in the eye, and usually causes no discernible change in vision. It might affect his ability to read fine print but that's about it. Rarely, if a dog lives to be very old and the sclerosis started in middle age, there is some vision loss. But for the vast majority of dogs, it causes no issues in vision, despite how it looks.Also Chase's eyes are blue but as he aged they have become cloudy blue it used to be only a little but now his eyes just cloudy blue maybe a little brown. Why? I wanted to clicker train him but I don't know if he can hear very well so I was going to use a light but I wonder if he can see it.
