After enlisting chickens and pigeons to sniff out deadly chemical toxins, the Department of Homeland Security is now training dogs to do the job, the New York Times reports.According to the paper, the pooches will be deployed at "airports, seaports, government buildings and other potential terrorist targets, where they will work alongside the police dogs that have long been used to sniff out narcotics, explosives and human remains."
