Like you, I was really really worried about this to begin with, and would peer intently into his eyes and worry about it. So glad when it disappeared though I know exactly what you are talking about. I thought I was going crazy, because my mom and my aunt couldnt see what I was talking about. I was thinking of having MY eyes checked!
But when we had the dog in for checks with KC, the vet noticed her eyes. Did some stains and tear tests, and some other things, and sent home some eye gel, and said it was fatty deposits.
I got her on a food called Solid Gold. It has low fat (10%), medium protien levels, and low phosphorus.
All I could think of, when I was seeing this, was like what Joy had, she had PRA, and I definately didnt want that!
