Thank you all! Yes he does very well already...it's only if something is out of place that he runs into it. The vet called me last night and said he tested negative for diabetes and whatever the other test was...I can't remember the name, so it's probably Progressive Retinal Atrophy (PRA), which is a hereditary problem in Springers. I'm going to talk to a specialist, but it's probably permanent, and I probably couln't afford to fix it even if it was fixable, so I guess he'll just always be blind. He is still a sweet, happy boy though
