Molecular Biomarkers of Adult Human and Dog Stress During Canine-Assisted Interventions: A Systematic Scoping Review

Positive relationships, including those between humans and other animals, particularly dogs, may be a way to reduce stress in humans. However, research into this area is relatively new, and a comprehensive review of the impacts of these interactions on humans and dogs has not been conducted. A scoping review of the scientific literature was conducted to explore what is known about the impacts of canine-assisted interventions on molecular biomarkers (e.g., cortisol and oxytocin) and associated measures (e.g., heart rate and blood pressure) of human and canine stress. As reported across 27 identified studies, canine-assisted interventions have consistently been demonstrated to elicit positive changes in human stress markers, and typically do not cause negative impacts on the studied canine stress markers. However, results were inconsistent across measures of stress. For example, in humans, it was common for a study to show improvements to cortisol levels but no change to self-reported stress, or vice versa. Many of the reviewed studies also had significant methodological issues, such as not aligning the timing of sample collections to when the analyzed stress biomarkers could be expected to peak. More rigorous research should be conducted on the impacts of canine-assisted interventions on a wider range of stress biomarkers

Prison-Based Dog Training Programs: Standard Protocol

Across the United States, the number of prison-based dog training programs (PDPs) has increased substantially over the past several years. Currently, there are approximately 255 PDPs across 47 states that operate in a variety of correctional settings; however, there is little information available on how to successfully develop and implement a PDP. As a result, the research team from the Institute for Human-Animal Connection (IHAC) has developed a standard protocol to help guide PDP development and implementation. This report identifies common practices of PDPs and incorporates both general and context-specific recommendations that were gathered from interviews with PDP staff, relevant literature, and content experts. In total, 21 interviews with 20 programs were conducted. PDPs were asked about several program features, including policies and procedures, key personnel, funding, materials, physical spaces, supervision and monitoring, safety considerations, animal welfare, handler selection and training, and program benefits. This report highlights the benefits of PDPs to dogs, humans, prisons, local communities, and society as a whole and identifies challenges related to funding, staffing, and operating in a correctional setting. Findings from the protocol point to the importance of planning, staffing, communication, internal support, and training curriculum in successful program implementation
