Pet Therapy: How Animals Help People Cope with Stress and Recover


Interacting with animals is increasingly viewed not merely as a source of positive emotions, but also as an additional tool for psychological support. Pet therapy is used in rehabilitation and for addressing anxiety; some medical facilities even allow patients to meet with their own pets. However, the effectiveness of this approach depends on the individual’s condition, and its implementation requires adherence to safety guidelines.
More Than Just Interaction: What Lies Behind Pet Therapy
Animal-assisted therapy—or "pet therapy"—encompasses practices that utilize contact with animals to provide emotional support, facilitate social adaptation, and aid in rehabilitation. Depending on the specific program, sessions may be conducted under the guidance of professionals and involve specially trained dogs or other animals. A distinct aspect of this field includes organized visits where patients can spend time with their own pets.
Interest in this approach stems from the fact that illness and prolonged medical treatment affect more than just a person’s physical state. Isolation, the restriction of one’s usual activities, and separation from loved ones can exacerbate stress and feelings of loneliness. In such circumstances, interacting with an animal can help restore a sense of normalcy and an emotional connection to home.
Scientific research suggests a potential reduction in anxiety and stress, and in some cases, a decrease in the subjective experience of pain. However, outcomes vary depending on the specific situation, and the quality of evidence differs across various programs. Therefore, pet therapy does not replace medical treatment but can serve as a complementary approach.
Why Contact with Animals Is Important During Rehabilitation
For an individual, who spends weeks or months in a medical facility, an encounter with a pet can hold special significance. A pet is linked to daily routines, family life, and a sense of stability—all of which are often missing during a long course of treatment.
A case in point is the "Pets and Company" program, launched on July 9, 2026, at São João Hospital—one of Portugal’s leading public university hospitals. Under this program, select patients are permitted to receive visits from their pets directly in their hospital rooms. The initiative brings together experts from the "One Health São João" program, the unit for infection prevention and control and antimicrobial resistance, and the hospital’s service for the humanization of medical care.
One of the patients, 65-year-old António, had been in the hospital for about three months, undergoing rehabilitation for balance and gait impairments. His wife brought their dog, Princesa, to the hospital—marking the second time the two had reunited over the course of 15 days. António described the pet as a member of the family and spoke of how much joy these visits brought him.

This episode demonstrates that emotional support does not always require a complex, structured program. Sometimes, simply restoring a familiar connection with an animal—one with whom a person has shared years of life—can play a significant role. While this patient’s personal story illustrates the potential benefits of such an approach, it does not, in itself, constitute proof of its medical efficacy.

Benefits Must Be Balanced with Safety
Allowing animals into medical facilities entails risks that cannot be ignored, including the potential for allergic reactions, injuries, and the transmission of infections. Therefore, any decision regarding such a visit must take into account both the patient’s condition and the specific environment in which the encounter will take place.
At São João Hospital, visits are not granted automatically. The attending physician or a nurse must initiate a review, after which specialists assess the potential benefits and risks. The preferences of other patients present in the designated area are also taken into consideration.
To gain entry, an animal must have veterinary documentation confirming that its vaccinations are up to date and that it has received parasite treatment. During the visit, the pet must be supervised by an adult. If the animal’s condition or behavior fails to meet the requirements of the established protocol, the visit may be terminated.
Humanizing Medical Care
The Portuguese initiative exemplifies a broader approach to organizing medical care—one that considers not only a patient’s diagnosis and physical condition but also their psychological needs. For individuals undergoing long-term treatment, emotional support can be a vital part of their daily hospital experience.
Pet therapy is not a universal solution and is not suitable for everyone. Its implementation requires individual assessment, professional oversight where necessary, and clear safety protocols. However, when organized effectively, interaction with animals can serve as an additional resource for patients, helping them cope with isolation and maintain a connection to their everyday lives.
Ultimately, the value of such programs lies not in pitting emotional support against medical requirements, but in finding a well-founded balance between the two.
