From THE SUN:
Eight-year-old mutt Edward had to have his eyes removed after developing cataracts. His blind owner Graham Waspe, 60, was devastated at the time, but was soon given two-year-old Opal to help him AND his canine friend.
Graham, from Stowmarket, Suffolk, said: "Opal's been great for both of us. I don't know what we'd do without her."
Opal arrived shortly after Edward retired and the two dogs got along fine.
