If they are glowing animal eyes the red eye will not correct this.
What I have done before is do a google search for "Labs, glass eyes, taxidermy animal eyes" find a photo of a dog looking in the same general direction as your dog was and then with a little bit of work in PSP, using the copy and paste as new layer for the new eye, erase the glowing eye and with a softer eraser blend the new eye into the lid area of your dogs eye.
Here is a photo of a cat who's eyes were completely glowing before I used the above technique to replace them.
I used to have a really good site with animal eyes but now I can't find it back!
Here is a tut or PS but it would work the same in PSP
