Most of the military's dogs pass through one Air Force squadron in San Antonio, and most of those dogs were born in Europe.
The Department of War keeps roughly 2,000 military working dogs on duty. They guard gates, search vehicles and buildings for explosives and drugs, track people, and deploy with special operations units. Most of them reach that job the same way: a breeder, usually in Europe, sells a young dog to a vendor or an Air Force buying team, and the dog spends months in training at Joint Base San Antonio-Lackland before it goes to work.
The newest figures come from a February 2026 Inspector General report, which counted 520 dogs at the Air Force's training squadron and 1,527 elsewhere in fiscal 2023. GAO's last detailed count, from February 2022, found 1,769 dogs managed by Defense components and 39 more managed by contractors. The Air Force had 564, the Army 469, the Navy 319, the Marine Corps 189 and Special Operations Command 140. The rest sat with agencies such as the NSA and the Pentagon Force Protection Agency. Across the whole federal government, GAO counted 5,159 working dogs in 40 programs.
The Air Force also counts teams. In February 2026 a spokesperson told CBS News the department has more than 2,200 working dog teams at 182 locations.
The most common breeds are German shepherds, Dutch shepherds and Belgian Malinois. Most are dual-purpose: the standard course gives each dog 65 days of detection training and 55 days of patrol work.
The Air Force runs the program for every service as the Pentagon's executive agent. The work happens at the 341st Training Squadron, which trains "over 600 handlers and nearly 300 canines annually." Air Education and Training Command now calls the squadron "the center of the Department of War Military Working Dog program," using the secondary name the Pentagon took on by executive order in September 2025.
The squadron also buys dogs for the TSA. A few organizations, including Special Operations Command, hold waivers to buy their own.
The department breeds only Belgian Malinois, with about 50 to 90 puppies born at Lackland each year. At six to eight weeks old the puppies go to volunteer foster homes around San Antonio and Austin, and they come back at about seven months for adolescent training. At about a year old, each one takes the same evaluation a purchased dog has to pass. A 2020 Air Force base article said around half of the puppies are not selected.
The program supplies 10 to 15 percent of the department's dogs, depending on the year and the source. In 2012 the goal was about a third.
Everything else is bought as a young adult, between one and three years old. Buying teams that include TSA representatives travel overseas about four times a year to test candidates. On one 2019 trip they looked at more than 300 dogs and brought about 130 home. On a 2021 trip to Poland they tested more than 100 and bought 45.
Most of those dogs are European. GAO reported that "roughly 85 percent of the dogs procured by the Air Force are from breeders located in either Germany or the Netherlands." Air Force data for 2019 showed that 407 of the 427 dogs it bought were born overseas. The Air Force's current overseas purchasing agreements, which run from 2022 to 2027, are with four vendors in the Netherlands, one in Germany and one in Poland. It also holds about 20 agreements with U.S. vendors, many of which import their dogs from Europe. Why so much of the supply sits in Europe is its own story.
An untrained dog is called a green dog. "Typically, training time is 120 training days or about six months before a MWD is ready to go to the field," according to Joint Base San Antonio, and it can stretch to 18 months depending on where a dog was bought. The dog keeps training with its handler after it reaches a unit. For a puppy born into the breeding program, birth to graduation takes about a year and a half.
Plenty of dogs don't make it. A 2020 Air Force base article put the share that pass the squadron's training at about half, and a commander at another base said "maybe half." Training targets reported in 2018 implied a higher yield, closer to three in four. Combined with the buying-trip numbers, that means fewer than half of the dogs tested abroad end up certified, and perhaps as few as one in five. On buying trips, candidates have to show "self-confidence, resourcefulness, and the ability to detect odors," according to the squadron. Across detection programs, most documented washouts are behavioral.
Most of a dog's cost comes after purchase. In 2019 the base's contracting squadron said a green dog "ranges from $5,500 to $6,500 dollars per canine," shipping included. Dogs from U.S. vendors ran about $3,500 more on average, largely because many of those vendors import dogs from Europe and resell them at a markup, according to Air Force data reported by Military Times.
Federal officials told GAO that "procuring and training a dog can cost approximately $65,000 to $85,000 per dog." The TSA puts its own cost at $65,000 to train a passenger-screening dog with its handler, and $26,000 for a conventional explosives detection team.
Other figures circulate online. "$20,000 to $40,000" comes from a 2015 Air Force article describing what a certified dog is worth, and "$150,000" from a retired handler's estimate quoted in 2018. Neither is a budget figure.
A 2025 study of military dogs discharged between fiscal 2019 and 2021 found an average service life of 6.4 years, counted from arrival at the training facility. Half were discharged for joint, spine and nerve problems. About 14 percent left for training reasons and 9 percent for fear or anxiety.
Retired dogs can be adopted. Robby's Law first allowed it in 2000. Congress later made adoption the default, put former handlers first in line, and in 2021 made transfers free. The 341st says its waitlist usually runs 12 to 24 months.
Supply is concentrated in a handful of countries, and the in-house breeding program is well short of its 2012 goal. The selection filter is steep, and every dog that fails on a buying trip or in training costs months. Care and capacity are under review too. A February 2026 Inspector General evaluation found that in August 2024, 230 dogs in non-training status at the 341st were "walked for approximately 10 minutes, four times per week or less," against a requirement of five hours a day of physical activity and social and cognitive enrichment. It also found aging, unsatisfactory kennels at 10 of the 12 sites inspectors visited, which "caused the death of four DoD MWDs from FY 2021 through FY2023." The Pentagon has since approved $26.6 million over five years for 51 more caretakers, though the report noted that a federal hiring freeze slowed hiring. The 2026 defense authorization act ordered minimum kennel standards.
General Sense works with the same dogs this pipeline produces. Each one costs tens of thousands of dollars and 6-12 months before it can fully work. Only the top 1-2% of the general population of dogs can become detection dogs because they have to clear a behavioral hurdle. We're building a way to read a detection dog's olfactory signal directly, so more dogs become eligible to work as a detection dog. This removes one of the major bottlenecks in our detection dog supply chain.
How many military working dogs does the U.S. have? About 2,000 in fiscal 2023, according to a 2026 Inspector General report. In 2026 the Air Force cited more than 2,200 working dog teams.
Where are military working dogs trained? At the 341st Training Squadron at Joint Base San Antonio-Lackland in Texas, which trains nearly 300 dogs and more than 600 handlers a year.
Where does the military get its dogs? Mostly from vendors in Europe, especially breeders in Germany and the Netherlands, and from U.S. vendors, many of which import. A breeding program at Lackland supplies 10 to 15 percent.
What breeds are military working dogs? Mostly German shepherds, Dutch shepherds and Belgian Malinois. The Malinois is the only breed the department raises itself.
How much does a military working dog cost? A green dog cost $5,500 to $6,500 in 2019. Buying and training one costs about $65,000 to $85,000, according to federal officials.
Can you adopt a retired military working dog? Yes. By law, former handlers get first priority. Adoption is free, and the 341st says its waitlist usually runs 12 to 24 months.
