“…Specific therapies differ in the goal of the therapy (physical, mental, emotional or social), choice of animal, form, structure, length, duration and number of administrations (they can be one-off or repeated). AAT can be practiced with various animals, but the dog is generally the most involved animal in therapy, mainly due to its social skills and easy training [ 17 ].
