Of these dogs, 20 are expert in detecting explosive materials while 10 have skills in finding clues from crime spots, police said.
The Labrador Retrievers are one of the most popular breed of dogs in Britain and the US.
The dogs were inducted in the Delhi Police's dog squad in a programme attended by Lt. Governor Najeeb Jung in the presence of Delhi Police Commissioner Alok Kumar Verma and other senior officers.
A police officer said these dogs were bought on March 18 from the army's Remount & Veterinary Corps based in Meerut in Uttar Pradesh.
"With the induction of these dogs, the total number of dogs in the squad have reached 60. Of the total dogs in the squad, 45 are skilled in detecting explosives and remaining are specialised in finding clues at crime spots," said a police officer.
The Delhi Police dog squad, which started in 1960 with 10 dogs in Mandir Marg and Model Town areas in central and north Delhi, respectively, is now spread across 11 Delhi Police districts and special units under the supervision of the Crime Branch.
