Research has shown that physiological, as well as psychological, effects may occur after an animal-assisted session. The first recorded animal interventions in the United States occurred in 1942 at the Pawling Army Air Force Convalescent hospital in Pawling, New York (Behling & Haefner, 2011). Interaction with pet animals and farm animals was hoped to relieve stress and exhaustion. In some research studies the physical activity of dog-walking has decreased catecholamines, which are hormones released during times of psychological and physical stress. The main types of these hormones are dopamine, epinephrine, and norepinephrine. Additionally, research has shown an increase in endorphins when engaging with a friendly animal (Marcus, 2013). This research study also found that dogs’ olfactory ability may alert them to changes in participants’ health
