Guests with Assistance Dogs in Your Vacation Rental: What the Law Says and How to Prepare

Assistance dogs are not pets. They are a form of medical support, and the law obliges you to accept them, even if your vacation rental has a 'no pets' policy. Rejecting a reservation with an assistance dog exposes you to sanctions that can exceed 3,000 euros. And worse: a devastating review and a discrimination complaint. In this post, I explain what the law states, how to distinguish a genuine assistance dog from a pet, what you can require, and how to prepare your property to avoid surprises.

What is an Assistance Dog (and what is not)

An assistance dog is an animal trained to help people with a recognized disability. It is not the same as an emotional support animal, although many people confuse them.

In Spain, assistance dogs are regulated by regional laws (each community has its own) and by the General Law on the Rights of People with Disabilities. There are several types:

• Guide dogs: for blind or visually impaired people.
• Service dogs: for people with physical disabilities.
• Alert dogs: for deaf people (alert to sounds).
• Medical alert dogs: notify of epileptic seizures, blood sugar drops in diabetics, etc.
• Autism support dogs: accompany people with autism spectrum disorder.

All of them must be officially accredited. They carry an ID card, a visible badge (harness or identification vest), and the user has documentation proving it.

Important: an emotional support dog (ESA in English) is not considered an assistance dog in Spain. It does not have the same legal recognition, and you cannot be forced to accept it if your property does not allow pets.

What does the law say: Can you refuse?

No. And it’s clear.

Law 51/2003 on equal opportunities, non-discrimination, and universal accessibility, along with regional laws on assistance dogs, requires allowing these animals access to all public-use establishments, including tourist accommodations.

This applies even if:

• Your listing states "no pets allowed".
• There is a homeowners’ association rule prohibiting pets.
• You claim allergies of other guests.
• You say the property is small.

No argument is valid. If you refuse the reservation because of the assistance dog, you are discriminating. And that has consequences.

Penalties for refusal

Fines vary by region but generally are:

Type of violation	Approximate amount
Minor	60 to 600 euros
Serious	601 to 6,000 euros
Very serious	6,001 to 30,000 euros

Refusing to accept an assistance dog is usually considered a serious infringement. Additionally, the affected person can file a discrimination complaint based on disability, which has a much stricter sanctioning regime.

How to tell if it’s a real assistance dog

You have the right to request accreditation. It’s not disrespectful; it’s your right. The guest should be able to show you:

• Assistance dog ID card (issued by regional authorities).
• The dog’s identification document.
• Vaccination record with up-to-date vaccines.
• Sometimes, accreditation from the training center.

The dog must also wear a visible badge (harness, vest, or tag). If someone claims "I have an assistance dog" but cannot provide proof, it is not an assistance dog. It’s a pet. And you can enforce your policy.

Key difference from a regular pet

Aspect	Assistance Dog	Pet
Mandatory access	Yes, by law	No, up to you
Official accreditation	Yes	No
Visible badge	Yes (harness, vest)	No
Can you charge extra	No	Yes
Can you refuse the reservation	No	Yes

Can you charge a supplement for the assistance dog?

No. This is also definitive.

An assistance dog is not a pet; it’s a "technical support" similar to a wheelchair or a cane. Charging extra for it would be like charging extra for crutches. It’s illegal.

You also cannot:

• Charge an additional "security deposit" just in case.
• Require extra cleaning that you wouldn’t ask of other guests.
• Restrict access to certain areas of the property (bedrooms, living room, etc.).

Of course, you can charge for actual damages if the dog causes destruction. But not preventively.

How to prepare your home for assistance dogs

Even if you cannot refuse them, you can prepare to make the stay comfortable for everyone. A few things that make a difference:

Before arrival

• Tactfully ask what type of assistance the dog provides. This helps you tailor the welcome.
• Confirm the breed and size in case you need to prepare something specific.
• Locate the nearest park or green area for walks.
• Prepare an area with easy-to-clean flooring where the dog can stay.

During the stay

• A clean water bowl in the kitchen is greatly appreciated.
• A small old towel or mat for the dog to lie on without touching the floor or carpet.
• Information about the nearest emergency veterinarian, just in case.
• If you have accessible cleaning products or chemicals, store them safely. Dogs are curious.

After departure

• Normal cleaning, paying extra attention to hair (vacuum or lint roller).
• If you have carpets or fabric sofas, an extra sweep is helpful.
• Ventilate well. Not because it smells bad, but to leave the property neutral for the next guest (who might be allergic).

What if subsequent guests are allergic?

It’s a real concern but manageable. A well-cared-for assistance dog leaves no more trace than any other dog. With thorough cleaning, vacuuming, textile washing, and ventilation, the property is ready.

If you’re unlucky enough that the next guest has a severe allergy, honesty is best: inform them that a dog was recently in the property. But this is not something you will be legally reproached for: the obligation to accept assistance dogs prevails.

What to do if you suspect deception

Sometimes, someone claims "it’s an assistance dog" when it’s not, to sneak in a pet without paying extra. It’s fraud, and you have the right to protect yourself.

Steps:

1. Politely request proof: ID card, official document, visible badge.
2. If they cannot show it, explain that you will apply your pet policy (whether extra charge or rejection if pets are not allowed).
3. Document the conversation in writing (platform messages, email).
4. If they insist and threaten, report to the platform (Airbnb, Booking) with the documentation.

Platforms have clear protocols for this. You cannot force them to charge the guest, but they can mediate.

How Autoregistro fits in

Whether or not you have an assistance dog, by law, you must register all guests over 14 years old in SES Hospedajes. The dog itself isn’t registered, of course, but its humans are.

Autoregistro does this for you: you send a link to the guest, they fill out their details conveniently from their mobile, and the data goes directly to SES Hospedajes. It costs 1 euro per month per property (less than a coffee) and saves you paperwork. Regardless of whether they travel alone, with an assistance dog, or with three children.

FAQ

Can I refuse an assistance dog if my building does not permit pets?

No. The law on assistance dogs takes precedence over homeowners’ association rules. If you have issues with neighbors, you can show them the regulation.

What if the assistance dog causes damages?

You can claim actual damages as you would with any guest. What you cannot do is charge a specific preventive deposit just because it’s an assistance dog.

Does an emotional support dog (ESA) count as an assistance dog?

No, in Spain. ESAs do not have the same legal recognition as accredited assistance dogs. You can apply your pet policy to them.

What documentation can I request?

Official assistance dog ID card issued by regional authorities, vaccination record, and sometimes accreditation from the training center. The dog must wear a visible badge.

Can I restrict the assistance dog to certain areas of the property?

No. The assistance dog must be able to accompany its user at all times and in all areas of the accommodation, including the sleeping area.
