Therapy Dogs and Assistance Dogs: Understanding the Difference
The terms therapy dog and assistance dog are often used interchangeably, but they describe two very different roles. Understanding the distinction helps clarify what each type of dog does and the legal rights that apply to them.
An assistance dog is trained to perform specific tasks for one person with a disability. Examples include guide dogs for people with visual impairments, hearing dogs for deaf people, and medical alert dogs that detect conditions such as epileptic seizures or hypoglycaemia. Assistance dogs have legal access rights under the Equality Act 2010, which means they can accompany their owner into shops, restaurants, taxis, and other public places where dogs would not normally be permitted.
A therapy dog, by contrast, visits multiple people in settings such as hospitals, hospices, care homes, schools, and universities. The dog works alongside its owner-handler and provides comfort and companionship through interaction. Therapy dogs do not have the same legal access rights as assistance dogs and are only admitted to premises by prior arrangement with the institution. The bond that a therapy dog builds is with the people it visits, not with one specific owner in the assistance sense.
Pets As Therapy: The UK's Leading Organisation
In the UK, the most widely recognised therapy dog programme is run by Pets As Therapy, commonly known as PAT. Founded in 1983, PAT is a national charity that registers and supports volunteers with their dogs and cats to carry out therapy visits across the country. The organisation has tens of thousands of registered volunteer animals and facilitates millions of visits per year to NHS facilities, care homes, schools, and other settings.
PAT Dogs, as the registered animals are known, carry an identity card confirming their assessed status. This card provides reassurance to institutions accepting a visit and confirms that the animal has met the charity's standards.
Temperament Requirements for Therapy Dogs
Not every well-behaved pet dog is suited to therapy work. The demands of visiting unfamiliar environments, interacting with many different people, and remaining calm in noisy or emotionally charged settings require a particular type of temperament.
A suitable therapy dog should be friendly and approachable with strangers of all ages, including people in wheelchairs, with walking aids, or using medical equipment. The dog must show no signs of aggression, excessive fearfulness, or uncontrolled excitability. Crucially, the dog should genuinely enjoy human contact. A dog that merely tolerates being stroked will not thrive in this role and may develop stress-related behavioural problems over time.
The dog should also be comfortable in unpredictable environments. Hospital wards involve unfamiliar smells, sudden sounds from medical equipment, and interactions with people who may move unexpectedly or have restricted mobility. A dog that startles easily or becomes anxious is not a safe choice for this work regardless of how gentle it is at home.
The PAT Assessment Process
To register with Pets As Therapy, the dog and its owner-handler must undergo an assessment carried out by a trained PAT assessor. The dog must be at least nine months old and be fully vaccinated, regularly treated for parasites, and in good health. A veterinary certificate of health is required as part of the registration process.
During the assessment, the assessor observes how the dog responds to being approached by strangers, how it behaves when handled by someone unfamiliar, and how it reacts to sudden noises or unexpected movements. The assessor also evaluates the handler's ability to read the dog's body language and manage the dog calmly and confidently. Both the dog and the handler are assessed together, because the effectiveness of therapy visits depends on the partnership between them.
Dogs that pass the assessment are registered for a set period and must be reassessed regularly. If a dog's circumstances or health change significantly, the handler is expected to report this and pause visits if necessary.
Breeds Suited to Therapy Work
While any breed can theoretically be suitable for therapy work if the individual dog has the right temperament, certain breeds are consistently well represented in PAT programmes. Golden Retrievers, Labrador Retrievers, Cavalier King Charles Spaniels, and Cocker Spaniels are among the most common. Crossbreeds are also well represented. Smaller dogs are sometimes preferred in settings such as hospital beds or hospice chairs, where a large dog may be difficult to manage in a confined space.
What a Therapy Dog Session Involves
Sessions are organised in advance between the handler and the host institution. Visits to hospital wards, care homes, or schools typically last between one and two hours. The handler walks the dog through the setting, and staff guide them to individuals who have expressed an interest in meeting the dog. Visits are always voluntary, and no pressure is placed on anyone to interact with the animal.
During the visit, the dog will be stroked, spoken to, and in some cases sat alongside. For many elderly residents in care homes, a therapy dog visit may represent the most meaningful social interaction of their day. Handlers are trained to watch for signs that their dog has had enough and will end the session early if the dog shows signs of fatigue or stress.
The Proven Benefits of Therapy Dog Visits
Research into animal-assisted interventions has grown substantially in recent years, and the evidence base for the benefits of therapy dog visits is becoming increasingly robust.
Studies have shown that interacting with a dog reduces levels of cortisol, the primary stress hormone, and increases oxytocin, a hormone associated with bonding and relaxation. In clinical settings, patients who receive therapy dog visits have reported lower levels of pain, anxiety, and loneliness. In care home settings, therapy dog visits have been associated with increased social interaction between residents, improved mood, and greater engagement with staff.
In schools and universities, dogs are used to support students during examination periods and in reading programmes for children who lack confidence. Children who read aloud to a dog in a non-judgmental environment often show measurable improvements in fluency and confidence over time.
For people who are isolated or facing serious illness, the simple act of stroking a dog provides a form of comfort that is difficult to replicate through other means. Therapy dogs offer something that medicines and talking therapies cannot: unconditional, wordless companionship in the moment it is most needed.
