Assistance dog to an event: is a certificate required?

“With a certificate, the assistance dog is allowed to come along” – but which certificate?

For many people, a day out starts simply: you buy a ticket, check what time you need to be somewhere, and go there.

When you depend on a service dog, there is often an extra step involved: checking in advance whether your service dog is actually allowed inside.

Not because an assistance dog is a sociable pet that you would like to take along, but because the dog provides support due to a disability.

That is why a friend of mine recently asked at Comic Con Holland about the entry process with her service dog.

The answer was short and seemingly clear:

If you have a certificate for the assistance dog, it may come along.

Great: the service dog is allowed to come along.

But then another question arises:

Which certificate?

The problem with the word 'certificate'

The Netherlands does not have a single universal, legally mandated assistance dog certificate that every assistance dog user is required to present in order to be allowed entry somewhere with their assistance dog.

There is also no single assistance dog pass issued by the Dutch government that serves as official proof of identity for every assistance dog.

That makes a condition like “if you have a certificate” quite complicated.

Because what should someone bring along then?

• A pass from a training organization?

• A doctor's statement?

• A training certificate?

• A statement showing that someone has a disability?

• Or a document stating which tasks the dog performs?

And above all: which document is exactly meant and on what grounds is precisely that document required?

That is not just a discussion about words. For someone who depends on a service dog, it can determine whether or not they can enter.

An assistance dog is not just a guide dog for the blind.

That gives rise to another problem.

At the time of writing, the Comic Con Holland FAQ states the following regarding the question of whether pets are allowed:

No. Only guide dogs are allowed.

Moreover, there is talk there about bringing the correct documents and materials.

However, a broader wording is used elsewhere on the website, in the general terms and conditions. There, under the accessibility information, it states that trained service animals of visitors with a disability are welcome, in accordance with the location's policy.

Those are substantively different formulations.

And that is important, because an assistance dog is much more than just a guide dog.

The central government mentions, for example

Assistance dogs for people who are blind or visually impaired, deaf or hard of hearing, have a physical disability, a mental disability such as autism or PTSD, have epilepsy, or have diabetes.

Moreover, a disability does not have to be visible.

This also means that you cannot necessarily tell from the outside why someone uses a service dog or what tasks that dog performs for its handler.

An access policy that refers exclusively to guide dogs for the blind therefore does not cover the various types of assistance dogs.

What does Dutch legislation say about access?

The legal basis lies, among other things, in the Equal Treatment on the Basis of Disability or Chronic Illness Act (Wgbh/cz).

The central government explains that people with a disability or chronic illness are entitled to equal treatment and that organizations must make effective adjustments in certain situations. The government explicitly cites allowing an assistance dog as an example.

On the information page about assistance dogs, the central government states that an assistance dog is allowed to accompany you to public buildings, hospitality venues, shops, banks, schools and universities, sports facilities, public transport, and taxis, for example.

The legal starting point is therefore not simply:

Dogs are prohibited, unless someone can show the correct assistance dog pass.

The question is whether someone needs an assistance dog due to a disability and whether allowing one should be provided as an effective accommodation.

Does this mean that a service dog literally has to go inside always and everywhere?

No. Nuance is important in that regard as well.

The obligation to make an effective adjustment is not unlimited. Circumstances may exist in which a particular adjustment is disproportionately burdensome or in which other significant interests play a role.

This is also evident from rulings by the Netherlands Institute for Human Rights.

This was the ruling of the Board in 2024 regarding a physiotherapy center that did not allow an assistance dog. In that specific situation, according to the Board, there was no prohibited discrimination. The center treated, among others, vulnerable patients with severe lung conditions and was unable to sufficiently separate the dog from these patients within the practice in question.

In another case from 2024, the Board actually ruled that Amsterdam UMC had made prohibited discrimination by refusing a man access to a location because of his assistance dog.

It is therefore about the specific circumstances.

That is fundamentally different from a general rule that an assistance dog is only welcome when the handler can show a certain “certificate”.

But surely an organization must be able to verify if it really is a service dog?

That is probably one of the reasons why terms like attestation, certificate, and assistance dog pass pop up so often.

An organization wants to prevent someone from taking an ordinary pet dog to a place where dogs are normally not allowed and then simply saying:

This is my service dog.

That practical question is understandable.

However, the answer to that cannot automatically be that there must therefore be one official Dutch assistance dog document.

Because that document does not exist as a single universal access pass issued by the government.

Various training organizations may issue their own passes, certificates, or other documents. However, that does not automatically make such a document the definitive Dutch legal entry pass for assistance dogs.

And then there is another important group: people who train their assistance dog themselves.

The central government explicitly states that people can obtain an assistance dog through an assistance dog organization, but that someone can also train a dog themselves.

This makes the problem with a generic requirement like “show the certificate” even clearer.

From which authority should that certificate then originate?

A card is not the same as a legal status

I find that distinction important.

An organization can issue a pass to the teams it has trained or supervised. Such a pass can be incredibly useful in practice.

It can quickly make it clear that dog and handler form a team together and prevent many conversations at the door.

But practically convenient is different from being legally required.

A card from a private organization does not suddenly become a mandatory assistance dog certificate required by the Dutch government just because it looks official.

The same applies to a vest or cover.

There are all kinds of designs, logos, colors, and texts. These can provide recognition, but a specific model of cover does not legally make a dog an assistance dog — just as the absence of one does not in itself mean that it cannot be an assistance dog.

And what about medical information?

We need to be careful with that as well.

When someone uses an assistance dog due to a disability, a request for proof quickly touches upon medical and other sensitive personal data.

That does not mean that nothing may ever be asked in every conceivable situation. But “just show me a doctor’s certificate” should not be used as an automatic standard answer without considering the necessity and legal basis thereof.

Moreover, a medical certificate regarding a person's disability does not automatically prove anything about the training or duties of a dog.

This brings us back to the same problem:

What exactly is an organization trying to establish, and what evidence is truly necessary for that?

Notably: the information from Comic Con Holland itself also differs.

That is precisely why the example of Comic Con Holland is interesting.

A friend asks directly if her assistance dog can come along and receives the following answer:

If you have a certificate for the assistance dog, it may come along.

Meanwhile, the FAQ discusses guide dogs for the blind and the correct documents.

And the general terms and conditions refer to trained service animals of visitors with a disability.

As a visitor, you are therefore presented with multiple formulations that do not necessarily mean the same thing.

• Does the dog have to be a guide dog for the blind?

• Are other service dogs also allowed?

• What do they mean by a certificate?

• Which documents are accepted at the entrance?

• And what happens when someone has a self-trained assistance dog and therefore does not possess a pass or certificate from a training organization?

  
  

Those are questions that can largely be prevented with one clear accessibility regulation.

This is not about trashing Comic Con Holland.

I want to explicitly state that.

This article was not written to pillory a single event.

In fact, the answer shows in any case that they are willing to allow a service dog.

The problem lies primarily in the terms and conditions and the information surrounding them.

Comic Con Holland thus serves as a practical example of something that assistance dog users encounter in many more places.

Do you have a pass?

Do you have a certificate?

Do you have a certificate?

Which organization does your dog belong to?

It all sounds very official.

However, when subsequently asked exactly which legal document is meant, it regularly turns out to be much less clear.

Accessibility begins at the front door

Accessibility is not just about a wheelchair-accessible entrance, a disabled toilet, or whether a service dog is eventually allowed through the door.

It starts with the information beforehand.

Someone without a service dog reads on the website when the event starts, buys a ticket, and can go.

An assistance dog user sometimes needs to send an email first. Then explain what type of assistance dog he or she has. Next, figure out what proof is meant. Perhaps medical information.

take along. Maybe call a training organization. And then the uncertainty sometimes remains as to whether the employee at the entrance applies the same rules.

That is also an accessibility barrier.

And that is precisely why clear information would make such a big difference.

Not:

Assistance dogs are permitted with a certificate.

But specify concretely which assistance dogs are welcome, what conditions actually apply, what may be asked at the entrance and — if a document is required — exactly which document that is and why.

Then visitors know what to expect.

And people who depend on a service dog for their independence do not have to prove time and again that they are allowed to enter together at all.
