Therapy Dogs service people other than the handler. They are used to comfort people in stressful situations such as people in rehab centers, veterans centers, children's hospitals, dental offices, or after disasters.
Therapy Dogs need to be trained similarly to Service Dogs. Therapy Dogs must have obedience training, Canine Good Citizen testing, and Public Access training.
Therapy Dogs need respond to the stress of others with a comforting paw or head in the lap of the distressed person.
