Because Ben is blind, he has a guide dog named Bill. Bill is a Jack Russell terrier. So is Ben. In February, a dog-pound owner found the dogs living on the streets of Averley, England. The pooches, both about 4 years old, had formed a special bond. Now, when Ben needs help getting around, he grabs hold of the back of Bill's neck, and Bill helps lead him.
