This is an oldie-but-goodie type of story, and seriously, it gets us a little sniffly every time we hear it. Graham Waspe's guide dog, Edward, had given 6 years of wonderful and loyal service to his legally blind owner when the dog, an eight-year-old Labrador, contract a rare form of Glaucoma and was left blind himself. Though Waspe and his wife were devastated at first, their grief quickly turned to joy when Edward's replacement guide dog, Opal, turned out to be a guide superdog.
Not only is Opal capable of carrying out Edward's former tasks, she's also able to help Edward get around and has become a close canine companion for him. Upon becoming fast friends, Edward now follows Opal closely and listens to her foot-fall to help guide him around.
Edward lives with the Waspes as a retired guide dog and family pet nowadays, and he and Opal make school presentations together where Edward gets to enjoy his favorite activity—getting lots of love, attention, and belly rubs from the kids at school.
