Therapy dogs may improve the emotional well-being of some cancer patients, according to results of a clinical study, the first to document the benefits of animal-assisted therapy in adult cancer patients. The research was published this month in the Journal of Community and Supportive Oncology.
The results show a significant improvement in quality of life for more than 40 patients who took part in a trial at Mount Sinai Beth Israel in New York City, where they interacted with therapy dogs following chemotherapy and radiation treatments.

The study, conducted by researchers at Mount Sinai Beth Israel, found that patients receiving intensive multi-modal radiation therapy and chemotherapy for gastrointestinal, head or neck cancers experienced increases in emotional well-being and quality of life when they received visits from a certified therapy dog during the course of their treatment.
Increases in emotional well-being were significant over the course of the animal-assisted visits, even as patients underwent marked and significant declines in both physical and functional well-being.
“This study is the first such definitive study in cancer, and it highlights the merits of animal- assisted visits using the same scientific standards as we hold for the cancer treatment itself. It shows the importance of an innovative environmental intervention during cancer treatment,” said Stewart B. Fleishman, MD, principal investigator and Founding Director of Cancer Supportive Services at Mount Sinai Beth Israel. “Having an animal-assisted visit significantly improved their quality of life and ‘humanized’ a high-tech treatment,” he said. “Patients said they would have stopped their treatments before completion, except for the presence of the certified Good Dog Foundation therapy dog and volunteer handler.”
“Thanks to this rigorously designed study, we now have strong evidence that pet therapy is an effective tool to help cancer patients get through challenging treatments,” said Gabriel A. Sara, MD, Medical Director, Infusion Suite at Mount Sinai Roosevelt, and Assistant Clinical Professor of Medicine, Icahn School of Medicine at Mount Sinai.
The study has been called another piece of ‘mounting evidence’ of how the human-animal bond can enhance emotional and physical health.
