Police dogs must remember several verbal cues and hand gestures. The most commonly used breeds are the German Shepherd, Belgian Malinois,

The beagles found it in less than a minute, while Fox Terriers took 15 minutes and Scottish Terriers failed to find it at all. Beagles are better at ground-scenting (following a trail on the ground) than they are at air-scenting, and for this reason they have been
