The role of the human-canine bond in recovery from substance use disorder: A scoping review and narrative synthesis

Abstract

Abstract Recovery from substance use disorder (SUD) is a personal journey that includes connection with self and others, including animals – known as the human-animal bond (HAB). Research shows that canines are the most common type of animal integrated into animal-assisted interventions to support people with SUD. Yet, to our knowledge, there has been no review of the evidence on the role of canines in SUD recovery. The scoping review’s objective was to examine the literature on the human-canine bond’s role in recovery from SUD among adolescents and adults, including how the bond may help or hinder recovery. The review considered records that described the human-canine bond with respect to recovery in any recovery- or therapy-related setting globally. Eleven databases were searched, and 32 sources met inclusion criteria that involved companion dogs, therapy dogs, service/assistance, dogs and others. The thematic analysis across records identified three key benefits of the human-canine bond in SUD recovery: (1) a source of social connection and a conduit for human-to-human social connection, (2) a calming and comforting effect on individuals with SUD that can reduce stress and anxiety, and (3) the human-canine bond as a motivating factor for positive change. Through these themes, the bond may help divert substance use-related thoughts and reduce cravings, bolster engagement in treatment and recovery, and help to decrease and prevent substance use. However, a few articles found no role or a limited role of the human-canine bond in recovery, and challenges and considerations were reported, particularly for marginalized populations (e.g., related to obtaining and maintaining housing, employment, and SUD treatment). Most of the records discussed canine welfare in some capacity. Calls were also made for improved policy, public awareness, and animal welfare.
