If an animal helps you manage anxiety, PTSD, depression, or other emotional health challenges and you need formal documentation, your first step is to get a valid ESA letter from a licensed clinician. This question-and-answer style guide is written to give clear, practical answers to the most common concerns people have about obtaining and using ESA documentation in 2025. Read each question as a short chapter — each answer aims to be actionable and to link you to the best page on Real ESA Letter for deeper help.

Q1 — What exactly is an ESA letter, and who writes it?

An ESA letter is a clinician-signed document that confirms, based on a professional evaluation, that an individual benefits from the presence of an emotional support animal. Licensed mental health professionals — psychologists, psychiatrists, licensed clinical social workers, and licensed therapists — commonly write these letters after assessing a patient’s needs. If you’re unsure who to ask, RealESALetter explains how clinician consultations work and what to expect during the evaluation in their piece on clinician consultations.

Q2 — How do I know which animal is right for me?

The best animal is the one that reliably helps you feel calmer, safer, or more able to function. Dogs and cats are the most common Emotional Support Animals because they are widely available, bond readily with humans, and are well-understood by veterinarians and trainers. For a breakdown of species, temperaments, and practical considerations, see the RealESALetter guide on types of emotional support animals. Consider your living situation, allergies, activity level, and the animal’s temperament when choosing.

Q3 — I want a dog — what should I know about training and certification?

While ESAs do not require the specialized task training that service animals do, basic training and certification-like preparation can make daily life smoother. Training helps with manners, leash behavior, and reducing noise — all of which reduce conflicts with neighbors and landlords. For specifics about preparing a dog to serve as an ESA and the expectations owners commonly face, RealESALetter’s article on emotional support dog certification offers practical tips.

Q4 — Are cats a good option for ESAs?

Yes. Cats can be excellent ESAs for people who benefit from calm, indoor companionship. They often require less space and daily outdoor exercise than many dogs, which makes them suitable for apartment living. If you’re considering a cat, the RealESALetter resource on emotional support cat guidance covers questions about housing, litter, and documentation considerations specifically for cat owners.

Q5 — What are the strongest legal protections for ESA owners?

Housing law is where ESA documentation has its clearest legislative backing. Under federal housing protections, reasonable accommodations may be required for tenants with qualifying disabilities who have ESAs. The RealESALetter overview on emotional support animal laws explains how federal statutes intersect with local enforcement and what to present to housing providers when seeking accommodation.

Q6 — How do I prepare documentation for a landlord?

Prepare a clean, professionally formatted ESA letter that includes the clinician’s name, license number, date, and a succinct statement that the patient’s mental health materially benefits from the animal. Offer to provide vaccination records and discuss reasonable accommodations (repairs, damage responsibility) if the landlord asks. If you’d like a template or examples of what landlords expect, RealESALetter’s housing resources and practical guides outline how to present your request effectively.

Q7 — Can veterans get special consideration for ESAs?

Veterans often access ESAs as part of a trauma-informed care plan. Clinicians familiar with veteran care can tailor letters to explain how an animal serves as a grounding or safety tool in the context of PTSD or anxiety. RealESALetter’s page about ESAs for veterans provides veteran-specific considerations and ways to coordinate letters with VA or community mental health services.

Q8 — Do ESA letters expire and how do renewals work?

Many clinicians date letters for a limited period (commonly 12 months) to ensure documentation reflects current clinical needs. Renewal typically involves a re-evaluation or a note from the treating clinician that the need persists. For timing and what clinicians typically look for during re-evaluations, see the RealESALetter guide on ESA letter renewal.

Q9 — What’s the difference between an ESA and a service animal?

Service animals are trained to perform specific tasks for people with disabilities (e.g., guiding a person who is visually impaired or alerting a person to a medical episode). ESAs provide emotional support through companionship and are not granted the same broad public-access rights. For a concise comparison that clarifies access and legal differences, RealESALetter’s post on the difference between ESAs and service animals is helpful.

Q10 — How many ESAs can someone have?

There’s no absolute federal cap on the number of ESAs a person may have, but having multiple animals can raise legitimate concerns for housing providers (space, noise, safety). RealESALetter’s article on how many ESAs you can have explains how clinicians and landlords typically evaluate requests involving more than one animal and how to present a justified case.

Q11 — Can a primary care physician write an ESA letter?

Some primary care physicians may document an ESA need if they have sufficient knowledge of a patient’s mental health and the state’s professional rules allow it, but many clinicians prefer the recommendation to come from a mental health specialist. If you’re considering asking your primary care doctor, RealESALetter’s guidance on primary care physicians and ESA letters outlines who typically writes letters and how to approach the conversation.

Q12 — How should I ask my clinician for an ESA letter?

Be direct and specific. Describe the symptoms that the animal helps mitigate and provide real examples (e.g., “petting my dog calms my breathing when panic starts” or “having my cat at night reduces insomnia by making me feel safe”). If you’d like suggested language or scripts to use, RealESALetter’s page about how to ask a doctor for an ESA letter includes phrasing clinicians commonly accept.

Q13 — How do I spot scams and choose a trustworthy provider?

Avoid services that promise instant approval, sell only certificates with no clinician review, or hide clinician credentials. A trustworthy provider will show licensed clinicians, explain the evaluation process, and provide a verifiable letter that includes clinician information. For a practical discussion on spotting bad actors and protecting yourself, Best Emotional Support Animal Letter Websites , which outlines warning signs and questions to ask before paying for documentation.

Q14 — What should I expect to pay?

Costs vary by provider and the services included (initial evaluation, letter PDF, renewals, verification support). Some platforms offer tiered packages or combined services for additional fees. For an example of transparent pricing and what typical packages look like, RealESALetter maintains an accessible pricing page that outlines common options and fees so you can budget accordingly.

Q15 — What if a landlord says the letter isn’t enough?

Ask for the objection in writing, verify what specific documentation they require, and offer to have your clinician confirm the letter if necessary. Keep all correspondence and, if needed, seek advice from tenant-rights or fair-housing organizations. Calm, documented responses tend to resolve disputes faster than heated exchanges.

Q16 — Do online ESA letters carry the same weight as in-person letters?

Yes — if the online service uses licensed clinicians who conduct a bona fide evaluation and issue a signed letter with credentials. The delivery method (online vs. in-person) is less important than the substance of the evaluation and the legitimacy of the clinician’s license. Always verify clinician details if a landlord or employer asks.

Q17 — How do I handle travel if an airline refuses my ESA?

Confirm the airline’s policy before booking, arrive early, present your documentation calmly, and ask for a written denial if the carrier refuses access. It’s wise to have contingency plans, such as alternate travel arrangements or trusted care for your animal. Because airline rules change, checking carrier policy pages can save you time and stress before your trip.

Q18 — Are there animal-care responsibilities specific to ESAs?

Absolutely. Regular veterinary care, updated vaccinations, behavioral training, and good hygiene are essential. Owners should also plan for backup care (friends, sitters) in emergencies. Responsible ownership not only protects your animal’s welfare but also helps maintain positive relationships with neighbors and housing providers.

Q19 — How do clinicians document the clinical need?

Clinicians typically document symptoms, functional impacts, and the ways in which an animal helps mitigate those symptoms. The letter usually includes clinician credentials, a statement of professional judgment, and a date. If a clinician requests specific evidence or records, provide what’s reasonable and necessary to support the assessment.

Q20 — Where can I learn more and find templates or examples?

Real ESA Letter’s site provides numerous educational posts and examples that outline documentation expectations, housing strategies, and renewal steps. If you want to explore sample letters, state-specific guidance, or deeper legal explanations, the Real ESA Letter blog and resources are a practical next step.

Frequently Asked QuestionsHow quickly can I get a legitimate ESA letter?

The timeline depends on whether you already have a clinical relationship and the provider’s process. If you see a therapist regularly, your clinician may be able to document the need and produce a letter within days or a couple of weeks. If you use an online evaluation or need a new assessment, expect a turnaround from a few days to a few weeks depending on appointment availability and whether additional records are requested.

What should be included in a valid ESA letter?

A valid letter should be on clinician letterhead, include the clinician’s name and license information, be dated, and state that the clinician has determined the patient benefits from an emotional support animal. It should avoid unnecessary medical detail but be specific enough to show a clinical judgment. If a landlord or other entity asks for verification, the clinician’s contact and license details allow for legitimate follow-up.

Do animal registrations or certificates carry legal weight?

No, "registrations" and marketing certificates without clinician evaluation do not carry the same legal weight as a clinician-signed ESA letter. They are often sold as convenience products but are not substitutes for a documented clinical recommendation and therefore may be rejected by landlords or other parties seeking proof of need.

Is it ever okay to get a letter from an online provider?

Yes — provided the online provider uses licensed clinicians who conduct a proper assessment and document findings appropriately. The deciding factor is the legitimacy of the clinician and the substance of the evaluation, not whether the meeting happened in person or online.

What if my landlord asks for my full medical records?

You are generally not required to disclose full medical records to a landlord. A clinician’s letter that states the need for an ESA and provides contact and license information is usually sufficient. If a landlord asks for more, consider seeking tenant-rights advice before sharing additional personal medical information.
