Yes, I agree that a blind dog can have a very happy life. Our tricolour sheltie has been blind for the last 4 years & we've learned how to make him safe & comfortable.
There's a good article about Living with a Blind Dog at: http://www.weir.net/~lglass/page5.htm
There's also a good site about Dogs with Disabilities at: http://members.bytemeusa.com/~dwd
I'm glad the little blind beagle pup is now safe & will have a loving owner.
