Tasks
The K-9 officers and their canine counterparts are frequently called upon to complete a variety of tasks, primarily during in-progress incidents encountered by patrol officers. Their services include:
- Criminal apprehension
- Building searches
- Area searches
- Evidence detection
- Narcotics detection
- Tracking missing persons
- Tracking fleeing suspects
- Crowd control
- Protecting the lives of their handlers and other law enforcement officers
Annual Certification
Each K-9 is assigned to an officer and lives with that officer and his or her family. In order to enhance the effectiveness and efficiency of the K-9 unit, continuous education is a top priority. Each K-9 and handler is trained and certified annually to meet the nationally recognized standards. Reliability and consistency in job performance is very important to our K-9 Units. Their ongoing proficiency training ensures each K-9 will act and perform according to expectations and standards, and that each handler knows how to elicit the best work from the dog. All handlers and their K-9s consistently exceed the number of expected hours for monthly maintenance training. The Seguin Police Department K-9 team literally saves hundreds of man hours each year searching for narcotics, criminal suspects, and missing persons. Our canines, with the use of their enhanced sense of smell, can search a location in a fraction of the time that it would take an officer or search team, therefore allowing our resources to be back in full service in a timely manner.
Community Service
Our K-9 Unit not only works diligently to provide the citizens of Seguin the protection they deserve, they continuously work to maintain a favorable relationship within the city by actively participating in community events. This team spends numerous hours within our local schools educating our youth about drugs and prevention. They also work with many community groups and provide general K-9 demonstrations whenever possible.
