The Dog Squad has gained much publicity for its excellent contribution in investigating crimes. The creation of a dog squad had been recommended by B Shetty but it came into existence much after 1966. The squad was strengthened in 1993 with the creation of additional posts of one ASI, two PCs, one PC (sweeper) for North Goa and one ASI, six HCs and one PC (sweeper) for South Goa. The ASI is the dog trainer and the HCs are dog handlers; the others are followers. The dog squad is used for tracing narcotics and explosives and tracking criminals. The dogs also lend colour to functions such as police parades where they perform with grace and win the hearts of the viewers.
