What Are Emotional Support Animals?

A practical example is that of patients with autism, who often find dogs or even cats to be a source of sensory stability.

Difference Between Emotional Support Animal, Regular Pet, and Service Dog

Many people confuse these categories, but each has distinct rules and functions.
While a common pet is just a pet, with no special rights, emotional support animals and service dogs have legal recognition in certain situations.
Common Pet
- Function: Company and affection.
- Access to public places: Restricted (shopping malls, restaurants and transportation may be prohibited).
- Example: A cat or dog without therapeutic documentation.
Emotional Support Animal
- Function: Psychological assistance, without specific training.
- Access to public places: Limited (accepted on air travel and condominiums, but not in all spaces).
- Example: A dog calming a patient with generalized anxiety.
Service Dog
- Function: Physical or psychiatric assistance (e.g., alert for epileptic seizures).
- Access to public places: Guaranteed by law (Law 13,146/2015 – Statute of Persons with Disabilities).

Who Can Have an Emotional Support Animal?
The indication for a emotional support animal must come from a mental health professional, such as a psychologist or psychiatrist.
Patients with disorders such as severe depression, panic syndrome, autism or PTSD (Post-Traumatic Stress Disorder) are the main beneficiaries.
An emblematic case is that of war veterans, who often develop PTSD and find in dogs a form of social reintegration.
In Brazil, projects such as “Healing Dogs” have already helped more than 500 people with this type of support.
However, it's important to emphasize that animals are not a substitute for medical treatment. They are a therapeutic complement, not a cure.
Furthermore, fraud in the issuance of reports has increased, leading airlines to require more rigorous assessments.

How to Get an Emotional Support Animal in Brazil?

- Report must contain ICD (International Classification of Diseases) related to the disorder.
- Animal Choice
- There is no species restriction, but dogs and cats are the most recommended for their social interaction.

- Documentation and Registration (Optional)
- In Brazil, there is no official registry, but some institutions issue emotional support certificates.
- Airlines may require a recent report (issued within 12 months).

Rights and Limitations in Brazil
Although they do not have the same privileges as service dogs, emotional support animals have some legal guarantees:
Air Travel
- Companies such as Latam and Gol allow transportation at no additional cost, provided a medical report is presented.
- In 2024, ANAC reinforced oversight to prevent fraud, requiring documents signed by professionals registered with the CRM or CRP.
Condominiums
- Law 4,591/64 (Condominium Law) cannot prohibit the presence of animals, unless there is a proven risk.
- Trustees may request a report, but they cannot arbitrarily deny it.
On the other hand, shopping malls, restaurants and public transportation are not required to accept these animals, as Brazilian legislation does not yet equate them to guide dogs.
Impact on Mental Health: Myths and Truths
Science has already proven the benefits of interaction between humans and animals. A study by USP (2023) showed that 72% of participants with moderate depression showed significant improvement after one year with a emotional support animal.
Truths
- Reduction of cortisol (stress hormone).
- Increased oxytocin (hormone linked to well-being).
- Improved socialization for people with autism.
Myths
- “Any animal can be an emotional support animal without documentation.” (False – a report is required).
- “It replaces therapy or medication.” (False – it is a complement, not a sole treatment).
How to Choose the Ideal Animal?
Not every pet is suited to this role. Some dog breeds, such as Golden Retrievers and Labradors, are better suited for their docile temperaments.
Cats can also be excellent, especially for people with reduced mobility.
Factors to consider:
- Size: A large dog may not be practical for those who live in an apartment.
- Temperament: Very agitated animals can increase anxiety rather than alleviate it.
- Life expectancy: A long-term commitment is essential to avoid abandonment.
Adopting from shelters is a great option, but it's important to check whether the animal has a calm and adaptable profile.
