Animal Assisted Play Therapy™ (AAPT) adds the elements of playfulness, humor, and lightness to the therapeutic process, and can be helpful for clients of all ages. It focuses heavily on relationships: how the relationship between therapist and animal must be developed in positive, mutually respectful ways in which the animals have a voice and choice whenever possible. This in turn provides a model for clients to help them strengthen their own relationships, not only with therapy animals and their own companion animals, but within the human relationships in their families and communities. The authors demonstrate how the techniques can be readily applied for dogs, horses, cats, and other animals. Many illustrative case examples are included.
