The History of Pet Therapy


Pets have always had a special place in our hearts, providing companionship, unconditional love, and support. As time passed, this bond between humans and animals became known as pet therapy. In this article, we will explore the fascinating history of pet therapy, looking at its origins, growth, and the significant positive effects on human well-being.

History of Pet Therapy

Ancient Beliefs in Animal Healing

Ancient civilizations acknowledged animals’ healing abilities, which marks the beginning of pet therapy. In those early cultures, animals were considered to have unique divine qualities, and people believed that being around them could promote spiritual and physical healing. Egyptian hieroglyphics even show cats, dogs, and other animals as symbols of protection and companionship.

Animals as Companions in Ancient Civilizations

In ancient civilizations, like Greece, animals played a crucial role in therapy for different ailments. Renowned physicians such as Hippocrates and Asclepius recognized how animals positively affected patients’ mental and emotional well-being. Healthcare facilities commonly kept animals to provide comfort to the sick and injured.

The Modern Emergence of Pet Therapy

The Role of Florence Nightingale

In the 19th century, Florence Nightingale, a pioneer in nursing, noticed small pets’ beneficial role in boosting hospital patients’ morale. She acknowledged animals’ calming effect on people and promoted their presence in healthcare facilities.

World War II and Therapy Dogs

During World War II, therapy dogs became prominent as they played a vital role in boosting soldiers’ spirits and offering companionship during challenging times. One dog named Smoky made a significant impact, setting the foundation for future animal-assisted therapy programs.

The Growth of Equine Therapy

In the 1960s, equine-assisted therapy, also known as horse therapy, became increasingly popular. Therapists discovered that engaging with horses benefited individuals facing physical, emotional, and behavioral difficulties. This discovery prompted the establishment of equine therapy centers around the world.

The Scientific Validation of Pet Therapy

Pioneering Studies on Animal-Assisted Therapy

During the late 20th century, formal studies on pet therapy started to surface. Dr. Boris Levinson’s research on the “Harry and the Dog” case brought attention to the emotional advantages of interacting with animals, especially for children with mental disorders. This work served as the groundwork for future research in this field.

Establishing the Human-Animal Bond

Researchers began studying the connection between humans and animals, acknowledging its positive impact on mental health and stress reduction. They found that the bond between humans and animals triggers the release of oxytocin, a hormone that fosters trust and bonding.

The Expanding Applications of Pet Therapy

Pet Therapy in Mental Health

Pet therapy has proven to be especially valuable in treating mental health conditions like anxiety, depression, and PTSD. Animals offer a non-judgmental presence that helps individuals feel comfortable to open up and express their emotions more freely.

Pet Therapy in Hospitals and Healthcare Settings

Hospitals started implementing pet therapy programs to enhance patient outcomes. Studies revealed that animal visits helped reduce blood pressure, lower pain perception, and accelerate recovery rates.

Pet Therapy in Schools and Educational Environments

Pet therapy also extended its benefits to educational settings, where animal interactions improved children’s social skills, attention spans, and overall academic performance.

Training and Certification for Pet Therapy

Criteria for Therapy Animals

Therapy animals undergo thorough training and assessment to guarantee effective and safe pet therapy sessions. A pet’s temperament, obedience, and socialization are essential to determine their eligibility for this role.

The Role of Handlers in Pet Therapy

Trained handlers play a vital role in pet therapy sessions. They oversee the interactions between the animals and clients, ensuring a positive and beneficial experience for everyone involved.

The Healing Power of Animal Companionship

Reducing Stress and Anxiety

Therapy animals have been proven to reduce stress and anxiety levels in individuals, leading to calm and relaxation.

Easing Depression and Loneliness

For those experiencing loneliness or depression, interaction with animals offers comfort and companionship, alleviating feelings of isolation.

Enhancing Physical Health

Besides promoting mental well-being, pet therapy also offers physical benefits. Interacting with animals can improve cardiovascular health and increase physical activity levels.

The Future of Pet Therapy

Advances in Animal-Assisted Interventions

As research continues, new interventions and therapies involving animals are likely to emerge, expanding the applications of pet therapy.

Integrating Technology with Pet Therapy

The future may witness technology integration in pet therapy, enabling virtual interactions with animals and enhancing the accessibility of such programs.


Pet therapy has come a long way from its ancient beginnings to its well-established position in modern healthcare and therapeutic practices. The human-animal bond has proven to be a powerful force for healing, providing emotional, mental, and physical support to individuals across various settings.
