people know. Dogs participating in Animal-Assisted Therapy (AAT) are encouraged to assist patients in some way needed and usually have a consistent, benevolent nature (“Pet Therapy”). All dogs are extremely intelligent animals. For example, when humans become upset, a certain smell is produced (Tagliaferro). When the smell is released, some therapy dogs are able to sniff it out and will usually aid the person (Tagliaferro). A common misconception is that therapy dogs are the same as service dogs.
