I didn't realize eye crud was due to dog food. My daughter has been feeding Lily Purina One small bites and Lily had them. She had to go to the vet for dehydration and she's been on Hills I/D and she doesn't have them now. But I need to switch to something else. I'm going to try her on Natural Balance Fish and Sweet Potato canned food because of low fat, moisture, and it's supposed to be easily digestible. I'll watch for the eye crud.
