Service Dog Tasks by Disability: A Comprehensive Guide
Service dogs are individually trained to perform work or tasks related to a person's disability. They may assist with physical, sensory, psychiatric, neurological, developmental, and other disabilities.
A diagnosis does not automatically determine the right tasks. The better starting point is the person's functional limitations: what is difficult, unsafe, or inaccessible, and what specific trained dog behavior could mitigate that limitation?
Emotional comfort or companionship alone is not an ADA service-dog task. This guide is for educational purposes and is not legal, medical, or disability-determination advice. Service dog needs should be evaluated individually.
Blindness and Low Vision
Possible trained tasks often focus on safe navigation, obstacle avoidance, and locating useful places or objects.
Navigation and guiding
- Guide along sidewalks, hallways, paths, and routes.
- Maintain a safe travel line.
- Navigate around stationary or moving obstacles.
- Avoid overhead obstacles.
- Stop at curbs, stairs, drop-offs, platform edges, and elevation changes.
- Navigate through doorways, crowds, narrow spaces, and temporary barriers.
- Find a safe path around blocked areas.
- Locate a familiar destination.
Intelligent disobedience
- Refuse a forward cue when proceeding would be unsafe.
- Refuse to cross when traffic presents an immediate danger.
- Refuse to step into a drop, opening, or unsafe area.
- Select a safer route when the requested path is blocked.
Finding locations
- Find a door, entrance, exit, stairs, elevator, escalator, restroom, service counter, checkout area, empty chair, vehicle, bus stop, crosswalk, curb ramp, or familiar person.
Deafness and Hearing Loss
Sound alerts
- Alert to a doorbell, knocking, telephone, mobile phone, alarm clock, timer, oven alarm, appliance alarm, smoke alarm, carbon-monoxide alarm, security alarm, medical-device alarm, baby crying, the handler's name, sirens, vehicle horns, workplace alarms, or another person trying to get the handler's attention.
Source indication
- Touch or nudge the handler when a sound occurs.
- Lead the handler toward the source of a sound.
- Lead the handler away from a danger-associated sound.
- Indicate the direction of a sound.
- Use different alert behaviors for different sounds.
Mobility Disabilities
Retrieval
- Pick up dropped objects.
- Retrieve a phone, medication, water, clothing, shoes, keys, wallet, purse, cane, crutches, walker, assistive device, emergency kit, or specifically named object.
- Carry an item to another person.
Doors, access, and environmental controls
- Open an adapted door using a pull strap.
- Pull a lightweight door or push a door closed.
- Activate an automatic-door button, accessibility button, adapted call button, accessible light, accessible switch, or specially designed environmental control.
- Open adapted cabinets or drawers and close drawers.
Wheelchair, dressing, and fall assistance
- Retrieve objects, accessories, and lightweight items for a wheelchair user.
- Pick up objects beside or under a chair.
- Pull a manual wheelchair only when appropriate for the individual dog and handler.
- Pull off socks, remove gloves, assist with removing jackets or sleeves using a trained tug, retrieve clothing, or pull a blanket into position.
- After a fall, retrieve a phone, emergency device, medication, or mobility aid; find another person; or activate a medical-alert system.
Balance and stability
Some dogs may be trained for carefully designed balance or stability work.
- Provide appropriately evaluated balance-related assistance for the individual handler's functional needs.
Weight-bearing, bracing, counterbalance, wheelchair pulling, and similar physical tasks require careful evaluation of the dog's structure, health, equipment, and the handler's needs. Not every large dog is suitable for these tasks.
Limited Dexterity and Paralysis
- Retrieve objects and place them into the handler's hand.
- Pick up dropped items.
- Retrieve a phone, medication, assistive equipment, clothing, or objects that would otherwise require dangerous bending or reaching.
- Pull open adapted drawers, close drawers, open accessible doors, close doors, and press accessible switches.
- Activate an emergency-alert button.
- Deliver an object to a caregiver.
- Pull clothing off or pull a blanket.
Neurological and Neuromuscular Disabilities
This may include conditions such as multiple sclerosis, muscular dystrophy, cerebral palsy, spinal cord injury, and related disabilities.
- Retrieve objects, mobility aids, medication, cooling supplies, or another designated disability-related item.
- Open or close accessible doors and activate accessible switches.
- Assist after a fall, summon another person, or activate an alert system.
- Carry lightweight items.
- Assist with adapted clothing.
- Perform wheelchair-related tasks.
- Lead the handler to a place to sit or rest.
- Interrupt unsafe movement associated with a neurological episode.
Seizure Disorders
Seizure-response tasks are trained responses during or after a seizure. Seizure-alert tasks involve a dog responding to a detectable precursor before the seizure, when that reliability has been demonstrated.
Seizure-response tasks
- Remain beside the handler during a seizure.
- Position appropriately to reduce movement toward hazards.
- Retrieve medication, a phone, or an emergency kit.
- Activate a medical-alert device.
- Get another person, alert a caregiver, or lead another person back to the handler.
- Provide trained post-seizure grounding.
- Remain with a disoriented handler.
- Guide the handler away from hazards during postictal confusion or lead the handler to a safe location.
Seizure-alert tasks
Some dogs may demonstrate an ability to detect physiological or behavioral changes preceding seizures.
- Give a nose nudge, paw touch, or persistent targeting behavior.
- Prompt the handler to sit or lie down.
- Retrieve another person.
- Bring medication or an emergency kit.
Not every dog can reliably predict seizures, and seizure prediction should not be promised simply because a dog is being trained as a seizure service dog.
Diabetes
Blood-glucose alert
- Alert to low blood glucose.
- Alert to high blood glucose.
- Give a trained indication for out-of-range glucose.
- Wake a sleeping handler.
- Persist until the handler responds.
- Alert another household member if the handler does not respond.
Response tasks
- Retrieve glucose, juice, another designated treatment item, a glucose meter, medication, a phone, or an emergency kit.
- Alert another person.
- Activate a medical-alert device.
A diabetic-alert dog should supplement, not replace, medically appropriate glucose monitoring.
Cardiac Conditions, Dysautonomia, POTS, and Syncope
Alert
- Alert to a reliably detectable physiological change.
- Alert to an impending fainting episode.
- Prompt the handler to sit or lie down.
Response

- Activate an emergency-response device.
- Get another person or alert a caregiver.
- Remain with the handler after loss of consciousness.
- Lead another person to the handler.
- Guide a disoriented handler to a seat or safe location.
Physiological or scent-based alert reliability varies and should not be guaranteed.
Migraine Disorders
- Alert to a reliably detectable pre-migraine change when demonstrated.
- Prompt the handler to take prescribed medication.
- Retrieve medication, water, a migraine kit, sunglasses, another adaptive item, or a phone.
- Lead the handler to an exit or quiet location.
- Guide a visually impaired or disoriented handler.
- Alert another person.
Severe Allergies and Anaphylaxis
Allergen detection
Depending on the specific trained allergen, a dog may be trained to:
- Detect a target allergen in food, on a surface, or in an object.
- Check a designated item.
- Give a trained indication when the allergen is detected.
Emergency response
- Retrieve epinephrine, medication, a medical bag, or a phone.
- Alert another person or find a caregiver.
- Activate an emergency-alert system.
Allergen detection is target-specific and should not be presented as a dog's ability to detect every contaminant or every concentration.
Respiratory Disabilities
- Retrieve an inhaler, respiratory medication, safe oxygen-related accessories, or a phone.
- Find another person.
- Activate an emergency-alert device.
- Alert someone if the handler becomes incapacitated.
- Lead the handler to a resting location.
- Carry a lightweight medical-supply pouch.
Tasks around oxygen or respiratory equipment should be planned carefully so the dog is not asked to interfere with medical equipment or create a safety hazard.
Narcolepsy and Sudden Incapacitation
- Alert to an impending episode when a reliable precursor exists.
- Prompt the handler to sit or move to a safe location.
- Guide the handler away from hazards.
- Remain appropriately positioned during an episode.
- Retrieve medication or a phone.
- Get another person or activate an emergency-alert device.
- Provide a trained orientation response afterward.
- Lead a disoriented handler to a safe location.
PTSD
Panic and episode interruption
- Detect observable precursors.
- Nudge the handler, paw target, nose target, or perform another trained tactile interruption.
- Interrupt escalating behavior and persist until acknowledged.
- Prompt a learned coping behavior.
- Lead the handler away from a triggering environment or to a safe location.
Grounding and nightmare response
- Perform trained tactile grounding, chin rest, or repeated nose targeting.
- Interrupt dissociation or reorient during a flashback.
- Wake the handler from a disability-related nightmare.
- Turn on an accessible light.
- Retrieve medication or find another household member.
Room checks, functional space, exit, and orientation
- Enter a room and perform a trained search, return, and indicate completion.
- Check behind a door or check a specific designated area.
- Stand behind or in front of the handler, maintain a defined position, or move around the handler on cue to establish usable space.
- Find an exit, lead the handler to an exit, locate a trusted person, guide the handler out of an overwhelming environment, or locate the handler's vehicle.
- Give a medication reminder or retrieve medication, water, or an emergency kit.
Room checks and safety checks are not attack, aggression, guarding, or protection tasks.
Panic and Severe Anxiety Disorders
- Alert to observable precursors of a panic attack.
- Interrupt escalating panic with a nose target, persistent tactile interruption, or trained grounding behavior.
- Lead to an exit or quiet location.
- Retrieve medication or a phone.
- Prompt a prescribed coping routine.

Simply giving the handler a reason to get out of bed because the dog needs care is companionship or routine, not necessarily an ADA task.
Dissociative Disorders
- Interrupt observable dissociative behavior.
- Perform persistent tactile grounding.
- Reorient the handler through a trained response.
- Lead to a safe location or away from traffic and hazards.
- Locate an exit or trusted person.

OCD
For disabling obsessive-compulsive disorder, possible tasks may include trained interruption or redirection of specific disability-related behaviors.
- Interrupt a specific compulsion.
- Interrupt self-injurious behavior, skin picking, hair pulling, or repetitive checking when it directly mitigates the person's disability.
- Perform a trained tactile interruption.
- Lead the handler away from a location associated with an incapacitating compulsive loop.
- Retrieve medication or provide a medication reminder.
Autism
Interruption, grounding, and regulation
- Interrupt self-injurious behavior or repetitive harmful behavior such as scratching, hitting, biting, or another defined behavior.
- Provide a trained tactile cue during overload.
- Redirect to a learned alternative behavior.

Elopement-related assistance
Elopement-related tasks should focus on non-force-based trained behaviors.
- Alert a caregiver when a defined elopement behavior begins.
- Find a caregiver.
- Lead the handler toward a predetermined safe location where appropriate.
Tethering a person to a dog or using the dog as a physical anchor raises welfare and safety concerns for both the person and the dog and should be evaluated carefully.
Intellectual and Developmental Disabilities
- Give medication reminders or retrieve medication.
- Retrieve a communication device or phone.
- Lead to a familiar destination or find an exit.
- Locate a caregiver.

- Guide to an exit, familiar location, or the handler's vehicle.
- Locate another person.
- Retrieve a phone, medication, mobility aid, or dropped object.
- Give medication reminders.
- Assist after a fall.
- Activate an emergency-alert device or alert another person.

Parkinson's and Movement Disorders
- Retrieve dropped objects, a cane, walker, medication, or phone.
- Open accessible doors and activate accessible switches.
- Get another person after a fall or activate an emergency system.
- Lead to a chair or resting location.
- Provide a trained external movement cue for freezing-of-gait episodes when appropriate.
- Perform targeting that assists initiation of movement.
- Assist with clothing using tug behaviors.

Physical-support tasks require the same careful evaluation of the dog's structure, health, equipment, and the handler's needs described in the mobility section.
Chronic Pain
- Retrieve objects to reduce painful bending.
- Retrieve medication, safe heating or cooling supplies, mobility aids, or a phone.
- Open accessible doors, close doors, and turn accessible lights on or off.
- Carry lightweight items.
- Get another person.

Energy-Limiting Disabilities
For ME/CFS and other energy-limiting disabilities, useful tasks often reduce repeated walking, reaching, or bending.
- Retrieve commonly needed items, medication, water, a phone, mobility aids, dropped items, or a medical kit.
- Open accessible doors, close doors, and activate accessible light switches.
- Carry lightweight items or bring items between rooms.
- Alert another person when assistance is needed.
- Reduce repeated walking, reaching, or bending through trained retrieval.
Connective-Tissue Disorders
For Ehlers-Danlos syndrome and related connective-tissue disorders, tasks may reduce risky movement and help during injuries or dislocations.
- Retrieve dropped items, mobility aids, braces, adaptive equipment, medication, a phone, or objects from low locations.
- Open accessible doors, close doors, and activate accessible switches.
- Carry lightweight objects.
- Find another person after an injury or dislocation.
- Activate an emergency device.
- Guide to a seat.
Heavy bracing and weight-bearing should not automatically be assigned. The dog's health, structure, equipment, and workload matter.
Balance and Vestibular Disorders
- Find a chair.
- Lead to a wall, railing, safe stopping place, or exit.
- Retrieve a mobility aid, medication, or phone.
- Get another person.
- Guide a disoriented handler.
- Provide a consistent positional reference.

Medication and Emergency Assistance
Medication and treatment assistance
- Give medication reminders.
- Retrieve medication, a medication bag, water, an inhaler, glucose, epinephrine, or other prescribed emergency supplies.
- Carry a small medical-supply pouch.
- Alert another person if the handler fails to respond.
Emergency communication and summoning assistance
- Retrieve a phone or bring an emergency communication device.
- Activate a dog-accessible emergency button or medical-alert device.

- Retrieve an AAC device or bring an emergency kit.
Finding people, places, and objects
- Find a partner, parent, caregiver, exit, vehicle, chair, elevator, restroom, service counter, medication, phone, mobility aid, or emergency kit.
Dogs generally retrieve or remind rather than administer medication.
Grounding and Behavioral Interruption
Interruption and grounding can qualify when the dog performs a trained response to disability-related symptoms, rather than merely providing passive comfort.
Behavioral interruption
- Interrupt self-hitting, skin picking, self-biting, scratching, hair pulling, another defined self-injurious behavior, or a destructive compulsion.
- Interrupt dissociation, a flashback, escalating panic, or a defined freezing response.
- Perform persistent nose targeting, a paw target, a chin rest, or retrieve another person when needed.
Grounding and reorientation
- Use repeated nose nudging, paw touch, chin rest, trained licking, or sustained targeting.
- Lead to a familiar location, find an exit, locate another person, interrupt dissociation, interrupt a flashback, or redirect the handler from a dangerous location.
Deep Pressure and Sustained Contact Tasks
The legally important issue is the trained behavior and disability-related function, not simply the phrase "deep pressure therapy."
- Place the head across the lap.
- Perform partial body contact across the legs.
- Use sustained chin or body targeting.
- Maintain contact until released.
- Perform the behavior in response to a trained symptom or cue.
What Does Not Count as a Service Dog Task?
Many ordinary dog behaviors are meaningful and helpful. They still do not, by themselves, constitute trained ADA service-dog tasks unless the dog has been trained to perform a specific disability-related behavior.
- Emotional comfort.
- Companionship.
- Reducing loneliness.
- Making someone feel safer simply because a dog is present.
- Crime deterrence resulting from the dog's presence.
- Petting the dog because it is calming.
- Sleeping with the dog because it is reassuring.
- General affection.
- Giving someone a reason to get out of bed because the dog needs care.
- Encouraging exercise simply because the dog needs walking.
- Ordinary pet behaviors that happen to improve mood.
Service Dogs vs. Protection Dogs
Service work should not be confused with aggression or personal-protection training. A service dog may perform nonviolent tasks that increase a handler's safety or functioning, but biting, attacking, aggressive guarding, threatening strangers, or personal-protection work are not appropriate service-dog tasks.
Appropriate nonviolent tasks may include PTSD room checks, finding another person, leading the handler away from danger, alerting to someone approaching when disability-related, maintaining trained positional space, or guiding a disoriented handler to safety.
How to Choose the Right Service Dog Tasks
Disability -> functional limitation -> situation -> trained dog behavior -> measurable benefit
PTSD: flashbacks cause disorientation; the handler may remain in an unsafe public location; the dog performs persistent tactile interruption and can then lead the handler to an exit.
Multiple sclerosis: bending causes instability; dropped objects cannot safely be retrieved; the dog picks up the object and places it in the handler's hand.
Diabetes: hypoglycemia may not be noticed promptly; the dog gives a trained alert to the relevant physiological odor change; the handler verifies glucose and follows the medically appropriate response.
Disabling depression: prescribed medication is repeatedly missed; the dog performs a trained medication reminder.
The goal is not to collect the largest possible list of tasks. The goal is to identify a small number of reliable trained behaviors that meaningfully increase the handler's independence, safety, or ability to function.
Frequently Asked Questions
What tasks can a service dog perform?
There is no exhaustive official list. A service dog may be trained to guide, alert, retrieve, interrupt disability-related behaviors, provide trained grounding, summon help, activate accessible devices, or perform other specific behaviors directly related to a person's disability.
How many tasks must a service dog know?
Under the ADA, there is not a required minimum number of tasks. What matters is that the dog is individually trained to perform work or a task directly related to the person's disability.
Does emotional support count as a service dog task?
Passive comfort, companionship, or emotional support by itself does not count as a service dog task under the ADA. A trained behavior that mitigates a disability-related symptom may qualify.
Can a service dog help with anxiety or PTSD?
Yes, psychiatric service dogs can qualify when they are trained to perform specific disability-related tasks, such as interrupting panic, grounding during dissociation, waking from nightmares, finding an exit, or prompting a trained coping routine.
Can a service dog remind someone to take medication?
Yes. A medication reminder can be a service dog task when it is trained to mitigate a disability-related limitation.
Can a service dog detect seizures?
Some dogs may respond to detectable changes before seizures, but seizure alert should not be guaranteed. Many seizure service dogs are trained primarily for seizure-response tasks, such as getting help, retrieving medication, activating an alert device, or helping the handler remain safe afterward.
Can service dogs detect blood sugar changes?
Diabetic-alert dogs may be trained to alert to out-of-range glucose changes, but they should supplement medically appropriate glucose monitoring rather than replace it.
Can a service dog perform more than one type of task?
Yes. Many service dogs perform several related tasks for the same handler, especially when those tasks address connected functional limitations.
Does a service dog need professional certification?
In U.S. ADA public-access contexts, the ADA does not require service animals to be certified or go through a professional training program. Other laws and settings can have different rules, so official ADA resources are the best starting point for federal public-access questions.
Official ADA Resources
These official U.S. Department of Justice ADA resources are useful starting points for federal public-access questions. Laws and procedures can vary outside ADA public-access contexts, including housing, air travel, employment, state law, and other situations.
Need Help Training Service Dog Tasks?
Training a service dog requires more than teaching individual behaviors. The dog also needs reliability, appropriate temperament, public-access skills, and task performance that holds up in real-world environments.
