ATF’s National Canine Training Center (NCTC) provides a variety of training programs for local, state, and federal agencies. Special agent canine handlers and external partners team up with explosives detection canines and accelerant detection canines to support criminal and fire investigations.

Canine handlers, the investigators who team up with ATF-trained K-9s, arrive at the NCTC with a variety of backgrounds dependent upon their K-9’s specialty. Seasoned ATF special agents as well as law enforcement, fire service, and intelligence agency personnel from local, state, and federal partners make the list of experienced candidates.
