History of Animal-Assisted Activities: From Moral Treatment to Modern Practice

Two hundred years before anyone called it therapy, a Quaker asylum kept rabbits on its lawns because the patients seemed calmer around them. The rest is a slow, surprising history.

Animal-assisted activities are structured programs that bring animals into care, education, and community settings to support comfort, connection, and engagement. Their history is less a story of medical breakthroughs than of social insight — a slow recognition, across centuries, that people often feel more at ease around animals, and that animals can be partners rather than mere amenities.

That single intuition gradually turned into organized programs welcoming animals into hospitals, schools, riding centers, and community spaces. This guide traces how that happened, from the earliest informal practices to today’s welfare-focused field.

Early Roots: Before the Practice Had a Name

Long before formal programs existed, animals appeared naturally wherever care and compassion were priorities. In the late 1700s and early 1800s, the “moral treatment” movement emphasized humane routines, quiet surroundings, and meaningful daily tasks. At the York Retreat in England — founded in 1796 by the Quaker William Tuke — small animals such as rabbits and birds lived on the grounds, both to calm the atmosphere and to give residents gentle responsibilities.¹

Across similar settings in Europe and North America, caregivers noticed that animals brought warmth into environments that could otherwise feel clinical or isolating. Writing in 1859, Florence Nightingale observed that a small pet was often an excellent companion for the sick — putting into words what many already sensed.²

Early 20th Century: Companionship and Rehabilitation

As hospitals and rehabilitation programs expanded in the early 1900s, animals kept appearing informally. Around 1944, the Pawling Army Air Force Convalescent Hospital in New York brought in dogs to help airmen recovering from what we would now recognize as combat stress.¹ These were ad hoc efforts rather than structured programs, but they showed that animals could play a natural, supportive role in daily routines.

At the same time, guide dog schools were building structured, ethical training systems for people who were blind. Those programs demonstrated that human–animal partnerships could be deliberate and well-organized, laying groundwork for the more formal animal-assisted approaches to come.

Mid-Century: Naming the Human–Animal Connection

By the 1950s and 1960s, the idea that animals could shape communication and comfort began entering professional discussion. The pivotal figure was Boris Levinson, a child psychologist who noticed that a withdrawn young patient opened up when his dog, Jingles, was accidentally present during a session. Levinson pursued the observation and, in 1964, gave it a name: “pet therapy.”³

Stories about Sigmund Freud’s dog Jofi, who sat in on sessions in the 1930s while Freud watched how the dog responded to patients, circulated in the same period. None of this amounted to a formal field yet, but it sparked real interest in studying the human–animal bond on purpose.

1970s to 1990s: Structure, Standards, and New Roles

Interest grew quickly in the late twentieth century. Hospitals, schools, and long-term care facilities began inviting trained volunteers and screened animals into organized visits, and as programs spread, safety guidelines, welfare standards, and handler training became essential. Professional organizations formed to clarify terminology and ethical practice, and to distinguish volunteer-based activities from more structured therapeutic work.

Species-specific roles also took shape during these decades. Dogs became common partners in indoor and community settings, horses developed their own branch of programs built around movement and horsemanship, and smaller animals found a place in residential environments where gentle, consistent contact mattered most.

Ethics and Animal Welfare

As the field grew, so did attention to the animals themselves. Programs increasingly emphasized reading stress signals, offering rest and rotation, using humane training, and giving animals real agency during interactions. The principle that an animal participates as a partner rather than a tool became central to responsible practice — a turning point that put sustainability and ethical oversight at the heart of the field.

What Contemporary Programs Look Like

Today, animal-assisted programs run across schools, riding centers, community organizations, and rehabilitation settings. They differ widely, but most share the same backbone: trained handlers or facilitators, clearly defined roles, an emphasis on safety and accessibility, consistent routines, and environments designed around both human and animal needs. Animals are matched thoughtfully to settings where they can thrive, and program policies increasingly reflect high standards for welfare and clarity of purpose.

Where the Field Is Heading

Two threads stand out in how the field is maturing. The first is precision: programs are more deliberate about pairing a species with the setting that suits it, so dogs tend toward indoor and community work, horses toward movement-based outdoor programs, and small animals toward residential or educational spaces. The second is integration — rather than standing alone, animal-assisted activities are increasingly woven into broader educational, recreational, and community initiatives, which helps normalize them instead of treating them as niche.

Underneath both runs a steadily deepening commitment to welfare science: facilitators trained to read subtle animal cues, and clearer lines between recreational, educational, and clinical settings so that participants know what to expect. Together these point toward a field that is thoughtful, sustainable, and built on partnership.

Conclusion

The history of animal-assisted activities shows how a simple observation — that people often feel more at ease around animals — grew into an organized, ethical set of practices. Over two centuries, caregivers, educators, and facilitators shaped settings where animals and people could meet in meaningful ways. Today’s programs continue that line, blending long tradition with careful attention to both human experience and animal well-being.
