Behind every successful police K-9 team is a lot more than a dog with a good nose. It takes specialized training, the right handler, a strong partnership, and countless hours of preparation. In this episode, I sit down with Mandi Brown, Director of Business Development; Jonathan Gardner, Senior Trainer; and Jonathan “John John” Dennis, K-9 Trainer and Handler, of K2K9 Solutions at the 2026 NCGIA Gangs and Violent Crime Training Symposium in Winston-Salem, North Carolina, to explore what goes into developing highly skilled working dogs that help protect our communities. From selecting and training puppies to detecting explosives, weapons, and narcotics, we take a behind-the-scenes look at the capabilities of police K-9 teams and the people who prepare them for the field. We discuss how dogs learn to recognize dangerous odors, why matching the right dog with the right handler matters, and what it takes to keep these teams performing in challenging environments. John John also takes us through a live K-9 training demonstration with Glam, a young Labrador retriever, showing how play, patience, self-discovery, and positive reinforcement help build a confident working dog. Whether you're in law enforcement, a K-9 handler, a dog enthusiast, or simply curious about what it takes to develop these remarkable teams, this conversation offers a fascinating look at the training, trust, and teamwork behind the badge.
