They're ready to report for duty in a new assault on crime: 20 new graduates of one of the government's biggest dog schools.
The new canine teams have been prepared by the Canine Enforcement Training Center in Front Royal, Virginia, to start their crime-fighting careers at U-S borders and airports around the country.
U-S Customs and Border Protection officials say the pooch patrols will be assigned to protect "the American people from possible terrorists attempting to illegally enter the U-S."
In their work for the Department of Homeland Security the dogs will be used to sniff out drugs or concealed humans, then sit at attention and wait for their reward.
In exchange for successful service, they're awarded a toy fashioned from a rolled-up terrycloth towel.
