The newest faculty member at the Uniformed Services University of the Health Sciences has a great smile 鈥 and a wagging tail.
Shetland, not quite 2 years old, is half golden retriever, half Labrador retriever. As of this fall, he is also a lieutenant commander in the Navy and a clinical instructor in the Department of Medical and Clinical Psychology at USUHS.
Among Shetland鈥檚 skills are 鈥渉ugging鈥 on command, picking up a fallen object as small as a cellphone and carrying around a small basket filled with candy for harried medical and graduate students who study at the military鈥檚 medical school campus in Bethesda, Md.
But Shetland鈥檚 job is to provide much more than smiles and a head to pat.
鈥淗e is here to teach, not just to lift people鈥檚 spirits and provide a little stress relief after exams,鈥 said USUHS Dean . He said students interacting with Shetland are learning 鈥渢he value of animal-assisted therapy.鈥
The use of dogs trained to help their human partners has ballooned since studies in the 1980s and 1990s started to show how .
But helper dogs come in many varieties. Service dogs, like guide dogs for the blind, help people with disabilities live more independently. Therapy dogs can be household pets who visit people in hospitals, schools and nursing homes. And then there are highly trained working dogs, that recently helped run down Islamic State leader Abu Bakr al-Baghdadi.
Shetland is technically a 鈥渕ilitary facility dog,鈥 trained to provide physical and mental assistance to patients as well as interact with a wide variety of people. His military commission does not entitle him to salutes from his human counterparts.

“The ranks are a way of honoring the services [of the dogs] as well as strengthening the bond between the staff, patients and dogs here,” said Mary Constantino, deputy public affairs officer at Walter Reed National Military Medical Center.
USUHS, which trains doctors, dentists, nurses and other health professionals for the military, is on the same campus in suburban Washington, D.C., as Walter Reed. Two of the seven Walter Reed facility dogs 鈥 (the former service dog for President George H.W. Bush) and 鈥 attended Shetland鈥檚 formal commissioning ceremony in September as guests.
The Walter Reed dogs, on campus since 2007, earn commissions in the Army, Navy, Air Force or Marines. They wear special vests designating their service and rank. The dogs visit and interact with patients in several medical units, as well as in physical and occupational therapy, and help boost morale for patients鈥 family members.
But Shetland鈥檚 role is very different, said retired Col. Lisa Moores, USUHS associate dean for assessment and professional development.
鈥淥ur students are going to work with therapy dogs in their careers, and they need to understand what [the dogs] can do and what they can鈥檛 do,鈥 she said.
As in civilian life, the military has made significant use of . 鈥淲hen you walk through pretty much any military treatment facility, you see therapy dogs walking around in clinics, in the hospitals, even in the ICUs,鈥 said Moores. Dogs also play a key role in helping returning service members with post-traumatic stress disorder.
Students need to learn who 鈥渢he right patient is for a dog, or some other therapy animal,鈥 she said. 鈥淎nd by having Shetland here, we can incorporate that into the curriculum so it鈥檚 another tool the students know they have for their patients someday.鈥
The students, not surprisingly, are thrilled by their newest teacher.
Brelahn Wyatt, a second-year medical student, said the Walter Reed dogs used to visit the school鈥檚 1,500 students and faculty fairly regularly, but 鈥渉aving Shetland here all the time is optimal.鈥 And not just because of the hugs and candy.
Wyatt said the only thing she knew about service dogs before 鈥渋s that you鈥檙e not supposed to pet them.鈥 But Shetland acts as both a service dog and a therapy dog, so he can be petted.
That helps medical students see 鈥渢here鈥檚 a difference. What does that difference look like in the health care setting?鈥 said Wyatt.
Like his colleagues Sully and Dillon, Shetland was bred and trained by America鈥檚 VetDogs. The New York nonprofit provides dogs for 鈥渟tress control鈥 for active-duty military missions overseas, as well as service dogs for disabled veterans and civilian first responders. Many of the by a combination of prison inmates (during the week) and families (on the weekends), before returning to New York for formal service dog training. such as the Washington Capitals and New York Islanders also raise puppies for the organization.
Dogs can be particularly helpful in treating service members, said Valerie Cramer, manager of America鈥檚 VetDogs service dog program. 鈥淭he military is thinking about resiliency. They鈥檙e thinking about well-being, about decompression in the combat zone.鈥 Often people in pain won鈥檛 talk to another person but will open up in front of a dog. 鈥淚t鈥檚 an opportunity to start a conversation as a behavioral health specialist,鈥 she said.
While service dogs for individuals are trained to perform both physical tasks like picking up dropped items and emotional ones like waking a veteran having a nightmare, facility dogs like Shetland are special, Cramer said. 鈥淭hat dog has to work in all different environments with people who are under pressure. It can work for multiple handlers, it can go and visit people, can go visit hospital patients, can knock over bowling pins to entertain or spend time in bed with a child.鈥
The military rank for the dogs is no joke. They can be promoted 鈥 as Dillon was from Army specialist to sergeant in 2018 鈥 or demoted for bad behavior.
Said Kellermann, 鈥淪o far, Shetland has a perfect conduct record.鈥
