The cuckoo’s call even before the sun has risen in the morning is often the only sound that precedes Gracy’s walk towards the training centre. The golden Labrador waits patiently by her kennel in the National Security Guard’s recently established K9 tactical training school in Manesar, Haryana, for her handler constable Amit Sharma to take her to the ground for the day’s exercises. A swift “Gracy chalo” has the dog bounding towards Sharma, and they walk, leg-to-leg, in the direction of the huge training ground.
