Thanks, Mary!

Actually his checkup was already scheduled for tomorrow, so I'm going to have his eyes looked at then.

I didn't know cataracts could do that! I know that in people they don't - because I used to work for an opthalmologist. I guess I should never assume that dog conditions are the same as human conditions.

He's only 7 1/2. He's a sheltie, so he could live to be 16. I'd hate for him to be blind for over half his life. He's really showing his age a lot lately. His arthritis is acting up today, for the first time in about 6 months. Poor guy!
