Human-animal bonding relationships have existed as long as humans and animals have lived, worked and played together--evidence of positive relationships between people and animals goes back thousands of years. More recently, dogs were used to help heal psychiatric patients in the military as early as 1919 and throughout various wars up until the present. However, a quick look at the literature examining the benefits of this intervention shows that we have a long way to go in building empirical support for the benefits of Pet Therapy. For instance, the Department of Defense does not currently have a department-wide policy regarding Pet Therapy and does not specifically endorse any project or certifying body. Animal Assisted Therapy is not currently listed as an evidence-based therapy for any specific disorder and is considered a complimentary or alternative therapy. On the other hand, there is ample anecdotal evidence of the advantages, and the utilization of Pet Therapy is growing rapidly.
