Over the past 20 years, there has been a steady rise in the number of programmes aimed at improving human health and welfare with the inclusion of animals.
They vary according to: 
Animal activity-based programmes involve animals (usually dogs) and their owners visiting people with additional needs, such as older people in nursing homes and people in hospices, who may benefit from seeing or interacting with a companion animal.
Volunteers and dogs of Pets as Therapy and Therapet undertake regular visits to care home, hospitals, schools and youth organisations each week. A recent study of 50 Therapet dogs confirmed the healthy status of the volunteer dogs; none were found with MRSA

Such programmes can also include educational visits to schools which promote the message of responsible pet ownership and is offered by a number of charities, including The Blue Cross. Sometimes dogs are involved in the specific development of skills in dog-assisted reading programmes such as R.E.A.D.
These visits are usually undertaken by volunteers of charities such as Pets as Therapy and Therapet. The participating animals are temperament-tested and health-checked.
More recently, a number of care farms and people working in farm-settings (eg Barton Hill ) have established visiting programmes encouraging individuals and groups to visit their farms, to advance skills and enhance self-development. In some programmes, groups can stay for several days and participate in a variety of farm activities, for example Jamie’s Farm.
