Sorry to hear that Millie has PRA.. Our Dylan started last year with cataracts and by Christmas both eyes had developed cataracts. I know how you feel I was devastated when I knew. BUT he has coped very well his life has not changed much, he still has off lead walks only on a long lead where their are woods, don't want him to have an injury. He still attends a training class, and fun dog shows
He like Millie is unsuitable candidate for the operation. We were told the same thing as yourselves. Dogs are very good and they do adapt, and there is a lot of things you can do to help them.
