Hospital stays are lonely. The sterile walls, the constant beeping of monitors, the parade of medical professionals taking vitals and delivering news. For patients on psychiatric units dealing with depression and isolation, that loneliness can become a weight that slows recovery. But at VCU Medical Center in Richmond, Virginia, a team of furry therapists has been proving for twenty-five years that sometimes the best medicine has four legs and a wagging tail.
The Dogs on Call program, one of the longest-running hospital therapy dog initiatives in the country, deploys more than sixty certified human-dog teams into patient rooms throughout the medical center. And now, a rigorous year-long study led by researcher Nancy Gee from VCU’s Center for Human and Animal Interaction has confirmed what patients and staff have felt all along: these dogs genuinely reduce loneliness.
The study, published in early 2026, followed sixty participants on the psychiatric unit who were experiencing depression and loneliness. Researchers designed three conditions, each involving twenty-minute daily sessions. Some patients received visits from a therapy dog and handler together. Others received visits from a handler alone, with no dog present. A third group received standard treatment with no additional visits.
The results were clear and compelling. The presence of the dog reduced loneliness significantly more than the handler alone, and far more than standard treatment. It was not just the social interaction that mattered. It was specifically the dog that made the difference.
Gee explained why therapy dogs occupy such a unique space in the hospital environment. Unlike every other person who enters a patient’s room, the dog is not there to draw blood, administer medication, or deliver a diagnosis. The dog arrives with no agenda other than being present. That simple, pressure-free companionship creates a space where patients can relax, open up, and feel genuinely comforted.
One of the program’s regular volunteer teams features Eliza Leitch and her therapy dog Luna, who walk the halls of VCU Medical Center bringing moments of joy to patients who often have very few. The sight of Luna padding softly into a room, ears perked and tail swaying, has a way of transforming the atmosphere instantly. Conversations start. Smiles appear. For a few minutes, the hospital room feels a little less clinical and a lot more like home.
The populations most affected by hospital loneliness include older adults, individuals with mental illness, and hospitalized children. For these groups especially, a therapy dog visit can be the emotional highlight of an otherwise difficult day.
Researchers continue investigating whether the benefits extend beyond the immediate visit, exploring questions about long-term impact on treatment compliance and patient outlook. But for the patients who have experienced a Dogs on Call visit, the answer is already clear. When a warm nose nudges your hand and gentle eyes look up at you without judgment, something shifts inside. The loneliness loosens its grip, even if just for a little while, and that can make all the difference.
