I have a poodle who was just diagnosed with this a few weeks ago... the specialist we took her to recommended this supplement
OcuGLO Rx | Canine Cataract | Cataract Dog | Dog Cataract Surgery | Dog Vision Problems
It is fairly new but the dogs who are using it are showing pretty good results- you may want to discuss this treatment with your vet.
Do you know how far along the damage is?
On another note- we had a poodle growing up who also had PRA and went blind at a very young age- she adapted very well to it and lived a very happy life anyway. You have to be careful with them and watch them more closely obviously but they really do adapt very well. It is much harder on us as the humans, we put our feelings on them a lot of times.

Let me know if you have any other questions.
