Animal-assisted therapy in schizophrenia

Animal-assisted interventions have become a more visible part of mental health care over the past two decades. In schizophrenia services they are offered both as informal "animal-assisted activities" — visits from therapy dogs to wards or community programmes — and as more structured "animal-assisted therapy" with defined goals and a credentialed practitioner.

The difference between AAT and AAA

Animal-assisted activities (AAA) are informal visits — a therapy dog comes onto a psychiatric ward, residents pet and interact with the dog, and the visit is meant to lift mood and engagement. There are no formal treatment goals.

Animal-assisted therapy (AAT) is a goal-directed intervention delivered by a health or mental health professional with a trained animal as part of treatment. AAT has documented goals (improved engagement, social interaction, reduced anxiety), measurable progress, and integration into the broader treatment plan. Pet Partners in the US and IAHAIO internationally publish standards for both types of intervention.

Why animals might help in schizophrenia

Several mechanisms are commonly proposed:

• Animals reduce social demand. Petting a dog or sitting with a cat does not require sustained eye contact, conversation, or social performance — making it tolerable for people with prominent negative symptoms or paranoia.
• Animals are non-judgmental. People with stigmatised diagnoses report relief at being received simply.
• Touch and rhythmic stroking activate calming physiological responses (lower heart rate, lower cortisol).
• Animals can serve as a bridge for human contact — a shared focus that makes group conversation easier.
• Caring for an animal (where appropriate) provides structure, purpose, and motivation.

What the evidence shows

The trial evidence for AAT in schizophrenia is limited but consistently small-positive. A few small randomised studies — including work by Calvo and colleagues with dogs in inpatient settings — have shown improvements in negative symptoms, engagement, and social interaction compared with treatment as usual. A 2018 systematic review in Frontiers in Psychology noted modest but positive effects across studies, while emphasising methodological limitations and the need for larger trials.

Major guidelines like NICE do not specifically recommend AAT for schizophrenia, partly because the evidence base is too small. But it is increasingly offered in inpatient units, day programmes, and recovery houses around the world, and patient experience is consistently positive.

Where AAT fits in care

AAT is usually an adjunct, not a primary therapy. Common settings include:

• Inpatient psychiatric units — therapy dog visits to lift ward mood, support engagement, and offer comfort during difficult days
• Day programmes and partial hospitalisation — weekly or monthly AAT sessions integrated with group therapy
• Recovery and rehabilitation programmes — longer-term work where caring for animals is part of structured recovery activity
• Outpatient settings — therapists who include their own credentialed animal in sessions for specific clients

What an AAT session looks like

A session usually involves a credentialed handler, a trained animal (most commonly a dog), and one or more participants. The therapist or handler may guide the session through specific activities — grooming, training cues, walking, simple games — or allow open interaction. The session is debriefed afterwards, often noting what came up in the participant: a mood shift, a memory, a conversation that started around the animal.

Pets at home are not the same thing

Owning a pet has its own benefits, and many people with schizophrenia describe their pets as central to recovery — see our piece on pets and mental health. But pet ownership is different from AAT. AAT is a structured intervention with goals and a clinician. Pet ownership is daily life with all the responsibilities and rewards that come with it.

Safety, hygiene, and screening

Reputable AAT programmes follow strict safety standards. Animals are health-screened, temperament-tested, and certified through organisations like Pet Partners. Hand hygiene, infection control, and patient screening (allergies, fear, immunocompromise) are routine. AAT in inpatient settings is coordinated with infection control to prevent risk to vulnerable patients.

Who tends to do well

• People with prominent negative symptoms who find direct social demand difficult
• People with anxiety alongside psychosis
• People in inpatient or transitional settings looking for a non-clinical bright spot
• People who genuinely like animals

Who may find it less useful

• People with significant fear of animals
• People with severe allergies
• People whose voices or delusions involve animals in distressing ways
• People who simply do not enjoy animals

Equine-assisted variants

Working with horses is a separate and well-developed field — see our companion piece on equine-assisted therapy for details specific to that work.

Cost and access

AAA visits in inpatient units are usually free to participants. AAT delivered by a private practitioner may or may not be covered by insurance. Many community mental health centres and clubhouses partner with local therapy animal organisations to offer regular sessions at no cost. The Pet Partners and Therapy Dogs International websites can help locate teams.

The bigger picture

Animal-assisted therapy is unlikely to be the centre of treatment for schizophrenia. It is a quietly meaningful adjunct — one that many patients describe as the part of their week they look forward to. In a treatment landscape dominated by medication, talk therapy, and clinical procedure, the steady warmth of an animal can be a different kind of medicine.
