In 2014, a St. John Ambulance Therapy Dog program dog and handler team began visiting the Regional Psychiatric Centre (RPC) in Saskatchewan. Inmates and staff quickly recognized that the structured visits were having a positive impact on the inmates’ lives. In fact, based on the experiences of the inmates who took part in the visiting program, the therapy dogs appeared to instinctively support evidence-based trauma principles used by health care service providers. Of course, they don’t know it’s called that. They’re just friendly.
