Therapy Dogs: What They Do and Whether Your Dog Could Be One

A therapy dog is a dog that visits people in places such as hospitals, care homes, schools, libraries and hospices to give them comfort and affection, working alongside its owner as handler. Unlike a service dog, it is not trained to perform tasks for one disabled person, and unlike an emotional support animal, its work is with strangers rather than its own family. Whether a dog can do this well depends far more on temperament and preparation than on breed. This guide explains what therapy dogs do, how to tell whether your dog could be one, and how to protect the dog’s own welfare along the way.

What Is a Therapy Dog?

A therapy dog is trained to provide affection, comfort and support to many different people, not just its handler (Wikipedia, Therapy dog). Typical settings are hospital wards, retirement and care homes, schools and reading programmes, hospices and, in some countries, disaster response. The dog and its handler work as a team: the handler reads the dog, manages each interaction and decides when the session ends.

The idea is older than most people assume. In 1961 the American child psychiatrist Boris Levinson described how his dog’s presence helped young patients open up, and in 1976 the nurse Elaine Smith set up the first organisation to train dogs for hospital visits after seeing how patients responded to a chaplain’s dog.

Therapy Dog vs Service Dog vs Emotional Support Animal

The three terms are often confused, and the difference matters both for the dog and for the people it meets.

  • Therapy dog: visits and comforts many people, with its handler, by invitation of a facility.
  • Service dog (assistance dog): is individually trained to perform specific tasks for one person with a disability, such as guiding, alerting or retrieving. Some therapy dog organisations, such as Therapy Dogs International in the US, do not accept service dogs into their therapy programmes. The jobs are very different: a service dog’s attention belongs to its handler, while a therapy dog’s work is engaging with strangers.
  • Emotional support animal: an owner’s own pet that supports that person’s mental health at home. It needs no task training. Our guide to emotional support animals and mental health sets out how ESAs, therapy dogs and service dogs compare.

What the Evidence Shows

Studies have recorded lower levels of the stress hormone cortisol after physical contact with a dog in several groups, including children with insecure attachment, children on the autism spectrum, hospital patients with heart failure and healthcare workers. Occupational therapy patients have also improved fine motor skills by grooming therapy dogs.

The evidence has real limits. Reviews of animal-assisted therapy note that many studies are small and vary widely in how the sessions are run, which makes it hard to say how much of the benefit comes from the dog itself. A therapy dog visit is a welcome addition to care. It is not a treatment in its own right, and good handlers never present it as one.

Could Your Dog Be a Therapy Dog?

The most important quality is not friendliness but composure. A dog that loves everyone and greets them by leaping up is a poor fit for a ward full of frail patients. Look for a dog that:

  • Is calm with strangers. It accepts approaches from unfamiliar adults and children without jumping, mouthing or retreating. If greetings are still a problem, start with stopping jumping up.
  • Tolerates handling. It is relaxed when touched on the ears, paws, tail and body, including clumsy or uneven touch, and when hugged or held briefly.
  • Is unfazed by the environment. Wheelchairs, walking frames, trolleys, beeping equipment, lifts and slippery floors do not worry it.
  • Recovers quickly. If something drops with a clatter, the dog may startle, but it settles again within seconds rather than staying wary.
  • Is reliable on basic cues. Sit, down, stay, leave it and a loose lead are dependable in a busy, distracting place.
  • Enjoys the contact. A dog that merely tolerates attention is not a therapy dog, however well behaved. The work should be something it seeks out.

Age matters too. The US Alliance of Therapy Dogs, for example, requires dogs to be at least one year old and to have lived with their handler for at least six months, so puppyhood is preparation time rather than working time.

How to Prepare a Dog for Therapy Work

Build on socialisation

The groundwork is laid in puppyhood, during the period when dogs learn what is normal. A structured puppy socialisation plan that includes people of different ages, mobility aids, varied floor surfaces and everyday noise gives a future therapy dog the right starting point. With an adult dog, continue the same exposure gradually and at the dog’s pace.

Train with rewards, not pressure

A therapy dog must feel safe around people and equipment, and fear-based training works against exactly that. Positive reinforcement training builds reliable behaviour while keeping the dog’s association with people positive. Pair gentle handling with food so that being touched predicts good things, and practise in progressively busier settings. Avoid the common training mistakes that teach a dog to cope by shutting down.

Health and hygiene

Many people the dog visits are unwell or have weakened immune systems. Research has found changes to the microbiome of both patients and dogs after therapy sessions, and whether those changes matter in the long term is not yet known. Facilities therefore set health requirements. The Alliance of Therapy Dogs, for example, asks for up-to-date vaccinations and a negative faecal test within the past year. Keep your dog on its vaccination schedule, on parasite control and freshly groomed before every visit.

Assessment

Therapy dog organisations assess dog and handler together. The Alliance of Therapy Dogs, for example, starts with a handling assessment in which an evaluator watches the dog’s temperament and obedience and the handler’s control, followed by three supervised visits before the team is approved. Requirements differ between organisations and between facilities, in South Africa as elsewhere, so if you hope to visit a particular hospital, school or care home, ask it first which organisation or standard it works with.

Protecting the Therapy Dog’s Welfare

Therapy work is demanding for the dog, even when it enjoys it. In therapy animals, limited time to rest, multiple sessions and long sessions have all been linked to higher stress. Practical rules follow from that:

  • Keep visits short, and build in breaks with water and a quiet space.
  • Limit the number of sessions per week, and protect the dog’s rest days.
  • Learn your dog’s stress signals: lip licking, yawning, turning away, a tucked tail, whale eye or sudden sniffing. Our guide to how dogs think covers the body language behind them.
  • End a session the moment the dog is no longer comfortable, whatever the schedule says.
  • Retire the dog gracefully when age, pain or a change in temperament makes the work harder. Stiff joints, poorer hearing and lower tolerance of handling are all signs it is time.

The best therapy dog teams are the ones where the handler advocates for the dog first. A relaxed, willing dog does far more good than one that is simply enduring the visit.
