K9

K9 refers to working dogs, typically trained for roles such as search and rescue, security, detecting drugs or explosives, and assistive services. The term is derived from the phonetic alphabet for the letter "C," which stands for "canine." These dogs are highly trained, intelligent, and capable of performing specialized tasks that support law enforcement, military operations, and various service functions. Their keen senses, especially smell and hearing, make them invaluable in situations where human capability is limited. The term emphasizes their role as trained working animals, not pets.
