Dog Allergy and Assistance Dogs: Facts, Misconceptions and Practical Solutions

“But someone has an allergy.”

— and suddenly my assistance dog was no longer allowed in the school.

And that’s exactly where it starts to feel wrong for me.

Because I am very aware of my responsibility as an assistance dog handler.

I actively think about:

hygiene
nutrition
environmental impact
risks to others

Not because I have to — but because my dog goes places where other dogs do not.

👉 And precisely because of that, I also expect the same level of care on the other side when looking for solutions.

Not just focusing on the problem, but on what is possible.

There are sentences that sound perfectly reasonable on paper.

This is one of them.

“But someone has an allergy.”

And don’t get me wrong — allergies are real. They can be uncomfortable, sometimes even severe. They deserve careful handling.

But what often happens is that this one sentence suddenly shuts everything down.

No discussion. No weighing of interests. No search for solutions.

Only this remains:

👉 Then the assistance dog cannot enter.

How it went for us

At my son’s school, I was welcome.

With my assistance dog. As it should be.

Until a child arrived with a (general) animal allergy.

And everything changed.

Suddenly:

no dogs were allowed in the school
and I was no longer allowed inside either

Not partially. Not under conditions.

Simply: no.

👉 For our full personal story, see:“My child lost his mother at school — because of my assistance dog.”

What we didn’t actually know

What made it complicated?

There was no clarity about:

how severe the allergy was
what exactly triggered it
whether dogs were actually the issue

That fell under privacy.

And yes — privacy matters.

But at the same time, a decision was made with major consequences for others.

Without clarity about the actual level of risk.

Reality check: how common is this?

💡 Facts at a glance:

Around 10–20% of people have a pet allergy
Most experience mild to moderate symptoms
Severe reactions (such as anaphylaxis) to dogs are rare
Many people react more strongly to cats than to dogs

👉 Meaning: not every allergy automatically equals high risk.

What happens then

My son was affected.

He needs support. He needs me. And therefore also my assistance dog.

But from that moment:

👉 the possible allergy of one child outweighed the actual needs of another

And that is not a neutral decision.

While there were solutions

And this is perhaps the most frustrating part.

Because I suggested them.

an allergy suit for my dog
adjusted schedules
separate routes
keeping distance

I was not rigid. I was not difficult.

I was willing to adapt.

But there was no willingness to look at what was possible.

Where it often goes wrong

In theory, it sounds logical:

👉 no dog = no allergy symptoms

But in practice, that’s not accurate.

💡 Science shows:

Allergens are found in saliva and skin flakes
They spread via air and clothing
They persist in dust and furniture
They are even found in buildings without animals

👉 In other words: you cannot “organise them away” by excluding one dog.

What is a dog allergy, actually?

It is not an allergy to “the dog” itself.

It is a reaction to specific proteins, such as:

Can f 1 (most common)
Can f 2, f 3, f 4, f 5, f 6

These are present in:

saliva
skin flakes (dander)
sometimes urine

💡 These particles are microscopic and easily remain airborne or settle in environments.

Hypoallergenic dogs — fact or marketing?

This is a persistent myth.

👉 The honest answer:

There is no such thing as a 100% hypoallergenic dog.

What is true:

some dogs shed less
some spread fewer allergens

But:

💡 All dogs produce allergens.

What does make a difference

And this is important.

Allergen levels are influenced by:

coat care
washing frequency
environment (ventilation, dust levels)
the dog’s behaviour

👉 And here lies a crucial point:

Nutrition, hygiene, and allergens

What is often overlooked is that the condition of the skin and coat directly affects what a dog spreads.

A dog with:

stable skin
fewer skin flakes
a healthy gut

👉 will often spread fewer allergens in practice.

But there is also an important and honest side to this.

Because nutrition — especially raw feeding — introduces other risks, particularly in environments where assistance dogs work.

💡 In my previous blog, I explain this in detail:

👉 Raw meat and assistance dogs: hygiene, food safety, and responsible assistance dog ownership

There, I explain:

how bacteria can spread via coat and environment
why hygiene is crucial for assistance dogs
and which trade-offs handlers must consider

An assistance dog is not a pet dog

My assistance dog:

stays with me
does not roam freely
does not lie everywhere
is intensively cared for

💡 As a result, exposure is often:

more controllable
more limited
more predictable

A personal note — my son

My son has an animal allergy himself.

And still:

we visit others
we encounter cats
we adapt

Sometimes with medication. Sometimes with distance.

👉 Because having an allergy does not mean you can no longer go anywhere.

What actually helps with allergy symptoms?

💡 Effective measures:

For the environment:

good ventilation
regular cleaning
reducing dust

For the dog:

regular coat care
washing when needed
clean materials

For the person with allergies:

antihistamines
corticosteroids
managing exposure

👉 This is how allergies are normally managed — not by eliminating everything.

What happened legally

We had this assessed.

And something important came out of that.

The Netherlands Institute for Human Rights:
👉 solutions must be explored
Disputes Committee for Special Education:
👉 the balancing of interests was not sufficiently careful
👉 my child was disadvantaged
👉 exclusion was not self-evident

Additionally:

👉 my son was already enrolled, while the other child was yet to start —and that should have been taken into account.

The core of the issue

This is not just about allergy.

This is about:

👉 proportionality

The question is not:

“Is there an allergy?”

But:

👉 “How severe is it, and what is a reasonable solution?”

Because this could have been handled differently

There were options:

time agreements
designated zones
distance
protective measures for the dog
combination with medication

👉 There was room for tailored solutions.

But that space was not used.

What I want to say

Allergies are real.

But solutions are real too.

An assistance dog is not a luxury — it is a medical aid.

And that requires:

knowledge
nuance
and the willingness to look beyond the first reaction

In conclusion

We need to stop thinking in terms of:

👉 “yes or no”

And start asking:

👉 “how can we make this work?”

💡 And perhaps that is the most important question of all.

Sources and evidence

The information in this blog is based on a combination of scientific literature, guidelines, and practical experience in allergology and assistance dog care.

Key sources:

European Academy of Allergy and Clinical Immunology — guidelines on allergic conditions
World Health Organization — indoor air quality and allergens
Centers for Disease Control and Prevention — exposure to animals and health risks

Scientific studies:

Vredegoor DW et al. (2012) — Can f 1 levels in different dog breeds
Custovic A et al. (1998) — distribution of pet allergens
Liccardi G et al. (2010) — allergens in public spaces
Wood RA et al. (2018) — environmental exposure

Guidelines and positions:

Key insights:

allergens spread via dander, saliva, air, and dust
allergens remain present even without animals
no fully hypoallergenic dogs exist
exposure depends strongly on environment and behaviour

💡 In summary:

allergens cannot be completely avoided
raw feeding requires additional responsibility
and context — such as assistance dog use — makes that balance even more important
