A therapy dog is a dog trained to provide affection and comfort to people in hospitals, retirement homes, nursing homes, schools, with people with learning difficulties and stressful situations such as dissaster areas.
Therapy dogs come in all sizes and breeds. The most important characteristic of a therapy dog is its temperament. A good therapy dog must be friendly, patient, confident, at ease in all situations, and gentle. Therapy dogs must enjoy human contact and be content to be petted and handled, sometimes clumsily.
A therapy dog's primary job is to allow unfamiliar people to make physical contact with it and to enjoy that contact. Children in particular enjoy hugging animals; adults usually enjoy simply petting the dog.
