In the wake of the terrorist attacks on cities like Brussels and Paris, the city of New York and the NYPD are looking to increase the number of vapor dogs that are present on their subway system.
Dogs have proved to be much better at detecting illegal devices and substances, such as bombs, than any man-made tool, which is why the city wants to increase their presence on subways.
Training these vapor dogs isn't an easy job, though. For 15 months, each dog is required to go through rigorous training to be able to successfully sniff out moving explosive devices.
Once they graduate from their program, the dogs still need yearly retraining to keep up with the changing bomb technology. Not only is this training hard work, it's not cheap either. The cost of these 15 months of training is an astonishing $49,000 per dog.
Due to the intensive training and high costs, only 130 dogs have graduated from the program in the United States and an undisclosed number work with the NYPD patrolling the city's 400 subway stations.
While training dogs to sniff out bombs requires a large amount of resources, they're our best bet to keeping our cities safe. Thanks for keeping us safe, pups!
