K-9 Bloodhound Units

Bloodhounds in Law Enforcement

Bloodhounds are known for their keen ability to track scents and find people with their noses. These canines can also distinguish the scent trail of one human being from that of another. It has been estimated that their sense of smell is to be between 1,000 and 30,000 times as strong as that of a human being. This is why they are greatly used by police agencies all over the world.

K-9 Rizzo was assigned to Lieutenant Sheridan when she was 6 months old. After months of extensive training, K-9 Rizzo was placed in service in June of 2012.
