How many dogs work for the government? 

Dogs are not just beloved pets — they’re also key to many federal tasks like sniffing out dangers or finding missing persons. Thousands of canines serve in departments such as Homeland Security and Defense, with roles ranging from explosive detection to search and rescue. Here’s the data on these skilled, furry professionals.  

  • About 5,600 dogs worked for the federal government in February 2022. Nearly all of them (5,159) worked for 40 federal programs across eight departments and three independent agencies. Another 421 were contractors.


  • Most government-employed dogs worked for the Department of Homeland Security (2,943 dogs), the Defense Department (1,808), the State Department (204), and the Agriculture Department (148).

Number of working dogs by federal departments and independent agencies

  • Twenty-six government programs use dogs to identify explosives, radiological materials, and nuclear weapons. Other jobs include narcotics detection, patrolling, and tracking missing people.


  • The Government Accountability Office (GAO) identified 18 issues critical to the health and welfare of working dogs, including inadequate housing, limited medical care, and poor planning for retiring older dogs. The GAO also says 32 of the 40 federally managed working dog programs had policies addressing at least 13 of these issues.
