what a police bloodhound does

A police bloodhound is a type of dog that is trained to help law enforcement officers by using their sense of smell to track down suspects or missing persons. They are often used in search and rescue operations, as well as criminal investigations. Bloodhounds have an incredibly strong sense of smell, which allows them to pick up scents that are days or even weeks old. When tracking a scent, a bloodhound will follow the trail of skin cells and other particles that a person leaves behind as they move through an area. They can also distinguish between different scents, which allows them to follow a specific persons trail even if there are other people around. Overall, a police bloodhound is an important tool for law enforcement officers, as they can help to locate missing persons and track down suspects in criminal investigations.
