About KPETS : What's the difference between AAT/AAA?

Animal Assisted Therapy or AAT uses registered volunteer team(s) of animal and handler who work with professionals in various health care disciplines to help facilitate patient healing and rehabilitation through specific care plans with goals and objectives. Progress is then documented and measured.
Examples of AAT are physical, speech and occupational therapies. Playing a tug game with a dog can improve strength. Range of motion can be worked on by tossing a toy for the dog to retrieve or by brushing the animal. Speech can be initiated by having the patient say commands for the dog to obey, or state the color of the ball he is about to toss. The AAT sessions can be implemented for psychological, social and cognitive goals, as well.

Animal Assisted Activities or AAA is a more casual type visit.
Examples of AAA would be one-to-one visits with one team visiting one client at a time. Group visits teams visit with a group of patients. Many times, AAA is done by groups of volunteers who go together to visit patients one-to-one or in organized group settings at a facility at a specific time. Putting on fun demonstrations of tricks, etc. to entertain patients in a group is another form of AAA.
