Built specifically around three conditions, not psychiatric disability broadly
One of the most widely cited psychiatric assistance dog task lists comes from the International Association of Assistance Dog Partners, with an original task list authored by Joan Froling in 1998 and subsequently updated over the years. The list is explicit about its own scope: it was developed specifically for people whose disability comes from panic disorder, PTSD or depression. This makes it an important historical reference point, but it was never intended to be a comprehensive framework covering every psychiatric condition equally, even though the broader idea of a "psychiatric assistance dog" gets applied more widely in everyday conversation.

A rare look at actual owners and actual tasks used day to day
A 2019 peer reviewed study, one of the few to actually survey psychiatric assistance dog owners directly rather than describing tasks in the abstract, found that participants reported a range of underlying diagnoses: depression in 84 percent of respondents, generalised anxiety in 60 percent, social anxiety in 61 percent, PTSD in 62 percent, and panic attacks in 57 percent, with many people reporting more than one condition. The tasks these owners reported their dogs performing, in order of how commonly they were reported, included:
- Reducing anxiety through tactile stimulation, such as the dog leaning against or resting on the person, reported by 94 percent of owners.
- Nudging or pawing to bring the person back to the present moment, reported by 71 percent.
- Interrupting an undesirable behaviour before it escalates, reported by 51 percent.
- Maintaining constant physical body contact, reported by 50 percent.
- Deep pressure stimulation, similar to what we described in an earlier FootNotes piece, reported by 45 percent.
- Blocking contact from other people in a crowded or overwhelming space, reported by 42 percent.
The same study also reported changes in healthcare use: 46 percent of owners said their use of psychiatric or other healthcare services had decreased, 30 percent said it had increased, and 24 percent said it had not changed. Participants who reported decreased use mainly attributed this to fewer suicide attempts, hospitalisations or medication requirements, while those reporting increased use mainly described being better able to attend appointments. These were self-reported associations, however, not evidence that the dog itself caused those changes. Both outcomes are worth taking seriously regardless, since an increase in appropriate healthcare use is not a failure, it can be exactly the kind of support a dog is meant to provide.

What PTSD involves, and what the tasks actually address
Post-traumatic stress disorder develops in some people following a traumatic event - sexual violence, accidents, natural disasters, the death of someone close, combat, sustained abuse or other experiences of profound threat. Its symptoms cluster into four main areas: intrusive memories and nightmares, avoidance of trauma-related situations, negative changes in mood and thinking, and heightened physiological arousal including hypervigilance and sleep disruption.
A psychiatric assistance dog for PTSD is trained to respond to specific symptom clusters with specific tasks. Tasks are tailored to the individual's presentation - not every person with PTSD needs every task, and the programme is built around what their daily challenges actually are. Some of the most commonly trained tasks include:
- Nightmare interruption. The dog is trained to wake its handler during a nightmare - responding to observable physical signs of distress during sleep, such as vocalisation or movement. After waking, the dog may be trained to move through the space and return, which may help the handler reorient to the present. Clinical assessment is important here: repeated checking behaviours can sometimes reinforce avoidance, so the task design needs to be individually assessed.
- Back watch. The dog is positioned behind the handler in public spaces, creating physical awareness of the space behind them. People with PTSD often experience intense discomfort with their back unguarded; this task directly addresses that specific trigger.
- Crowd blocking. The dog positions its body to create space around the handler in crowded environments, reducing uncontrolled proximity to strangers. This is particularly useful when PTSD symptoms are aggravated by close contact with people in public.
- Grounding during flashbacks or dissociation. The dog makes physical contact - a paw on the lap, leaning against the handler - providing a present-moment sensory anchor that may help interrupt the episode.
- Deep pressure on cue. The dog applies body weight across the handler's lap or against them during a panic or anxiety episode. This is one of the most commonly trained tasks for psychiatric assistance dogs working with PTSD.
- Medication and routine reminders. Some dogs are trained to prompt their handler at set times - nudging or retrieving a labelled item - to take medication. This supports routine adherence but does not replace a medication-management system or clinical guidance.
The evidence base for PTSD is the strongest within psychiatric assistance dog research, though it still has limitations. A 2022 systematic review and meta-analysis by Leighton and colleagues, published in PLOS ONE, examined 41 studies on psychiatric assistance dogs for military veterans with PTSD and reported a large, statistically significant effect on PTSD symptom severity. A 2024 non-randomised controlled trial published in JAMA Network Open, involving 156 military members and veterans with PTSD, found that adding a trained service dog to usual care was associated with significantly lower PTSD symptom severity, anxiety and depression after three months. Most of this research involves US military veterans; how well it transfers to civilian populations, and to Indian populations specifically, has not been studied.
In India, PTSD is underidentified and undertreated. The sources of trauma here differ from the combat-focused research literature - natural disasters, road accidents, domestic violence, sexual violence and other community-level trauma are significant. The tasks that address PTSD symptoms translate across trauma types, but the cultural context is specific to India, and most support will be home and community-based given India's current public access landscape for assistance dogs.

Conditions named often, but studied much less
Bipolar disorder, obsessive-compulsive disorder, schizophrenia and other conditions are regularly named alongside depression, anxiety and PTSD in general descriptions of psychiatric assistance work. Some structured dog assisted intervention research involving schizophrenia and related disorders has reported potentially beneficial effects, but that research generally concerns broader dog assisted programmes rather than individually trained psychiatric assistance dogs performing specific, disability mitigating tasks for one person. That distinction matters. We would rather say plainly that the evidence base for this whole field is limited overall, and it is especially sparse for condition-specific task effectiveness outside the areas that have received the most research attention. Anyone considering this kind of support for a less studied condition should treat it as a reasonable, individually developed approach worth discussing with a mental health professional, not an established category with the same level of evidence as the better-studied areas described above.
Why we stay close to what the evidence actually supports
Psychiatric assistance work, including tasks relevant to the conditions we have discussed here and in our earlier piece on anxiety, is one of the directions some of our Cohort 1 dogs are training toward. We think it matters to be specific about which conditions this kind of work actually has real evidence behind, rather than treating "psychiatric assistance dog" as one uniform category that works the same way for every diagnosis.
This is also a reminder that a mental health professional, not a dog trainer or an organisation like ours, is the right place to start for anyone wondering whether this kind of support could genuinely help their specific situation. We can train a dog to perform a task well. We cannot, and would not try to, diagnose which conditions that task will actually help.
