From the time the student is assigned his dog, the two are inseparable.
No one else feeds or cares for her and within a few days the two are
bound together by a mutual affection--a tie which remains unbroken
throughout the years of the dog's working life. Even about the house,
where no guiding is necessary, dog and man are constantly together just
because they want to be. She even sleeps close by her master's bed.
