Last week Delhi police warned dog owners to keep their petson leash when in public or to face jail up to six months. The days of the jolly littleterrier rollicking about are passe. These days rich folk keep dogs for security. In parksthere are mostly Dobermans, Alsatians and Bull terriers silently staring like ClintEastwood at all passers-by. These dogs definitely do need to be kept on leash.
