Therapy dogs provide relief to those in anxiety-provoking situations, bring comfort to those who are grieving or lonely, and offer affection to humans who are in institutions such as hospitals, nursing homes, and schools.

“On Tuesday, Oct. 8, 2019, a new systematic review and analysis of nearly 70 years of global research was published in “Circulation,” a Journal of the American Heart Association (AHA). The findings show owning a dog is associated with a 24 percent lower risk of death for all causes, compared with not owning a dog. For individuals with previous heart attacks or strokes, the benefits are even greater — a 31 percent reduced risk of early death.”


“Dogs are reportedly able to reduce social isolation,10 and dog ownership is associated with a lower risk of depression.11 It has also been shown that the presence of a dog attenuates blood pressure and heart rate response to stress in hypertensive patients.12”                     https://www.ahajournals.org/doi/10.1161/CIRCOUTCOMES.118.005342
