Therapy & emotional support animals

A service dog is trained to do specific tasks for a person that the person cannot do because of a disability. For mental health, this can include tasks linked to anxiety or PTSD.

See “Psychiatric service dogs” below for more.

An emotional support animal comforts through its presence and needs no special training. It does not have the same public access rights as a service dog.

Therapy animals visit places like hospitals, schools and care homes with their handlers to comfort many people. They are not service animals under the ADA.

In animal-assisted therapy, a trained professional includes an animal, such as a dog or horse, as part of a planned program. See “Therapy visits & animal-assisted therapy” below.

Examples from the ADA guidance

• Entering a room first and checking it, then signalling that it’s safe, for a person with PTSD
• Sensing an anxiety attack coming and taking a specific action to help prevent it or lessen it

A dog whose presence simply feels calming does not count as a service animal under the ADA.

The ADA does not require professional training. People with disabilities may train their own service dogs.

Training a reliable service dog takes a lot of time and skill. Many people work with an established service dog organization.

Service dogs don’t have to wear a vest, ID tag or special harness. Businesses can’t require documentation as a condition of entry.

Staff may only ask

• Is the dog a service animal required because of a disability?
• What work or task has the dog been trained to perform?

Staff can ask that a service dog be removed if it is out of control and the handler doesn’t take effective action, or if it isn’t housebroken.

In a VA study, 227 veterans with PTSD were randomly assigned a service dog or an emotional support dog, and followed for 18 months.

Both groups appeared to benefit. There was no difference in overall functioning or quality of life, but veterans with service dogs had a somewhat greater drop in PTSD symptoms.

In a 2024 study of 156 veterans and service members with PTSD, those who received a service dog had lower PTSD symptoms, depression and anxiety after 3 months than those on the waiting list. They also felt less socially isolated.

Participants weren’t randomly assigned, so the results need confirming. The authors describe service dogs as a possible complementary support, alongside usual care.

The VA’s National Center for PTSD says there isn’t yet enough research to know whether dogs help treat PTSD. Dogs can improve mood and reduce stress, but they are not a substitute for effective PTSD treatment.

Dogs can improve mood and reduce stress through companionship.

• A reason to get up and keep a routine
• Comfort during hard moments
• Company that eases loneliness
• Gentle exercise and time outdoors (for dogs)

Because emotional support animals are not trained for specific tasks, they are not service animals under the ADA. They don’t have the same right to go into stores, restaurants and other public places.

Some state or local governments have laws that allow people to take emotional support animals into public places, so check the rules where you live.

The VA notes that relying on a dog may sometimes delay learning to handle hard situations on your own, which can slow recovery.

An animal works best as one part of your support, alongside therapy and people.

In May 2026, HUD’s Office of Fair Housing and Equal Opportunity said it will find reasonable cause and recommend charges only in animal-related cases involving animals trained to provide disability-related help. It earlier withdrew its 2020 guidance on assistance animals.

HUD said this approach does not cover complaints under Section 504 of the Rehabilitation Act or the ADA, and that it plans formal rulemaking.

Since 2021, U.S. airlines don’t have to treat emotional support animals as service animals, and may treat them as pets. Trained psychiatric service dogs are treated the same as other trained service dogs.

Check your airline’s rules and forms well before you travel.

At work, bringing an animal is usually handled as a reasonable accommodation request. Employers with no-animal policies must consider changing them case by case for a service animal, unless it would cause undue hardship.

Whether employers must consider emotional support animals is less clear. The Job Accommodation Network (askjan.org) offers free guidance.

Equine-assisted services use horses in therapy, learning or horsemanship sessions. A 2024 review of 13 studies with veterans found PTSD scores dropped after these programs.

Other possible benefits included peer support, learning new skills and bonding. But almost all studies were low quality, so the authors urged caution.

A 2025 review of horse-assisted programs for PTSD, anxiety and mood conditions also found positive effects, but few well-designed studies.

A visit from a therapy dog can bring a moment of calm and connection during a hospital stay or a stressful exam week.

Therapy animals are not service animals under the ADA, so they don’t have the same public access rights. They visit places that invite them.

• How are the animals’ welfare and rest looked after?
• How does this fit with my other care?
• What happens if I’m nervous or have allergies?
• What training do the staff and handlers have?

Researchers also call for more attention to the welfare of the horses involved in therapy.

The VA does not provide service dogs for mental health conditions, including PTSD. It does cover veterinary care for certain service dogs that are medically necessary for veterans with permanent physical impairments.

The VA is studying whether service and support dogs help people with PTSD, and has said it will provide veterinary care for such dogs if research supports their use.
