Is the cockapoo a truly hypoallergenic dog breed?

No dog breed is truly hypoallergenic. Cockapoos may shed less than some breeds, but they still produce the Can f 1 protein in their saliva, dander, and urine. This allergen is the primary trigger for dog-related allergy and asthma symptoms. Allergy blood testing may help clarify whether you are sensitised to dog-specific allergens before or after bringing a cockapoo into your home.

Can a dog allergy develop later in life even if I was fine before?

Yes, allergic sensitisation can develop at any age. It is possible to live with a dog for years without symptoms and then develop a new sensitivity. If you notice a change in your respiratory health or develop persistent symptoms such as sneezing, itchy eyes, or wheezing, allergy testing may help identify whether a new sensitisation has developed.

What is a recommended allergy test for dog allergies?

Specific IgE blood testing is widely used in the UK to identify sensitisation to dog allergens, including Can f 1. This type of blood test does not require you to stop antihistamines beforehand, unlike skin prick testing.

Will allergy testing tell me which dog breed I can safely own?

Allergy testing identifies sensitisation to specific allergen proteins rather than individual breeds. Since all dogs produce Can f 1 to varying degrees, a positive result may indicate sensitivity to dogs in general.

Can dog allergens trigger asthma attacks?

Dog allergens can sometimes contribute to asthma flare-ups in sensitised individuals. Inhaled dander and airborne Can f 1 protein may cause airway inflammation, leading to symptoms such as wheezing, chest tightness, and shortness of breath.

How long do dog allergens stay in a house after the dog is removed?

Studies suggest that dog allergens can persist in a home for several months after a dog has left, particularly in soft furnishings, carpets, and mattresses.

Is allergy blood testing available in London without a GP referral?

Yes, private allergy blood testing is available in London without the need for a GP referral.

Can children be tested for dog allergies?

Yes, specific IgE blood testing can be performed for children, and it is a straightforward process that involves a standard blood sample.

Should I get tested before buying a cockapoo?

If you or a family member has a history of allergic conditions such as asthma, eczema, or hay fever, pre-pet allergy testing may be a helpful step.

Does bathing my cockapoo reduce allergens?

Regular bathing may temporarily reduce the level of airborne dander and allergen proteins on your dog's coat and skin. However, allergen production is ongoing, so bathing alone is unlikely to eliminate exposure entirely.

“Hypoallergenic” Dogs: Why the Cockapoo Might Still Trigger Your Asthma

Are Cockapoos Really Hypoallergenic? What Dog Allergy Sufferers in the UK Need to Know

The cockapoo has become one of the UK's most popular crossbreeds, and a significant reason for its appeal is the widespread belief that it is a hypoallergenic dog. For the millions of people across the country who live with asthma or allergic rhinitis, the promise of a dog that won't trigger symptoms is understandably attractive. However, the reality of dog allergens is more complex than many pet owners realise — and a cockapoo might still trigger your asthma or allergy symptoms regardless of its coat type.

Understanding the science behind pet allergens, and how allergy blood testing can help identify your specific triggers, may provide a clearer picture before you welcome a new pet into your home — or help explain persistent symptoms if you already have one.

What Does “Hypoallergenic” Actually Mean?

A hypoallergenic dog is generally understood to be a breed that produces fewer allergens or sheds less fur, potentially reducing the likelihood of triggering allergic reactions. However, no dog breed is truly allergen-free. The term “hypoallergenic” is not a medical classification and carries no clinical guarantee.

The primary dog allergen — a protein called Can f 1 — is produced in a dog's saliva, urine, and skin cells (dander), not solely in its fur. This means that even dogs with minimal shedding, such as poodles and poodle crosses like the cockapoo, still produce and distribute allergens throughout the home environment.

Practical Insight: The belief that low-shedding dogs are safe for allergy sufferers may lead to prolonged allergen exposure without understanding the underlying cause of symptoms. Allergy testing can sometimes help clarify whether dog-specific proteins are contributing to respiratory or skin-related symptoms.

Why Cockapoos May Still Trigger Asthma and Allergy Symptoms

The Can f 1 Protein Problem

Research published in the American Journal of Rhinology & Allergy has indicated that homes with so-called hypoallergenic dogs did not necessarily have lower levels of Can f 1 compared to homes with other breeds. The allergen is airborne, microscopic, and remarkably persistent — it can remain in a home environment for months, even after a dog has been removed.

Cockapoos inherit genes from both cocker spaniels and poodles, and their coats can vary significantly — from tight curls to wavy or even relatively straight fur. This genetic variability means that some cockapoos may shed more than expected, and all will still produce dander, saliva, and the allergenic proteins associated with symptoms.

Common Symptoms That May Be Linked to Dog Allergens

Individuals with sensitivities to dog allergens may experience a range of symptoms, which can sometimes be mistaken for other conditions:

Persistent sneezing or a runny nose that worsens indoors
Itchy, watery, or red eyes
Worsening asthma symptoms, including wheezing and chest tightness
Skin reactions such as hives or eczematous patches after direct contact
A chronic cough that does not seem linked to infection

Practical Insight: If symptoms appear to improve when you spend time away from home or away from the dog, this pattern may suggest an environmental allergen trigger worth investigating further.

Dog Allergens vs Other Common Indoor Allergens: A Comparison

It can sometimes be difficult to distinguish between dog allergy symptoms and reactions to other common household allergens — including cat dander. The table below outlines some key differences that may be helpful to consider:

Factor	Dog Allergens (Can f 1)	House Dust Mite Allergens	Cat Allergens (Fel d 1)
Primary source	Saliva, dander, urine	Mite droppings in bedding/carpets	Saliva, skin glands
Airborne persistence	Can remain for months	Settles quickly but re-disturbs easily	Highly airborne, very persistent
Common symptoms	Sneezing, asthma flare-ups, itchy eyes	Nasal congestion, morning sneezing	Wheezing, eye irritation, skin reactions
Affected by pet coat type?	Minimal — allergen is protein-based	Not applicable	Minimal — allergen is protein-based
Identifiable through blood testing?	Yes — specific IgE testing	Yes — specific IgE testing	Yes — specific IgE testing

Practical Insight: Because symptoms of dog, cat, and dust mite allergies can overlap considerably, blood testing for specific IgE antibodies may help distinguish which allergens are most relevant to your situation.

Who Should Consider Allergy Blood Testing?

Allergy blood testing — sometimes referred to as specific IgE testing — measures the level of immunoglobulin E antibodies your immune system produces in response to particular allergens. This type of testing can be particularly helpful for individuals who:

Experience persistent respiratory symptoms such as wheezing, nasal congestion, or coughing that may worsen around dogs
Have asthma that seems harder to manage despite following their usual management plan
Are considering getting a dog and have a personal or family history of allergic conditions
Already own a cockapoo or other dog and have noticed new or worsening symptoms since the pet joined the household
Want to understand their allergen profile to make informed decisions about their home environment

It is worth noting that allergy testing does not confirm a diagnosis on its own. Results are most meaningful when considered alongside your symptom history and discussed with an appropriate healthcare professional.

Our Allergic Rhinitis/Asthma Profile includes specific IgE testing for dog dander alongside other common indoor allergens. Dog dander is also covered within the UK Aero Allergen Profile, or you can request it as part of an individual allergen test.

How Often Should You Consider Allergy Testing?

For individuals with known allergic conditions or asthma, periodic allergy testing may be helpful in understanding how your allergen profile changes over time. Sensitisations can develop at any age — it is entirely possible to tolerate a pet for years before developing a new sensitivity.

As a general guide:

Baseline testing may be useful if you are experiencing unexplained or persistent allergy-like symptoms
Repeat testing every 12–24 months can sometimes highlight new sensitisations, particularly if symptoms change or worsen
Pre-pet testing — before bringing a dog into the home — may provide helpful information if you have a history of allergic rhinitis, eczema, or asthma

Practical Insight: Allergy profiles are not static. A negative result several years ago does not necessarily mean you remain non-sensitised today, particularly if your living environment or symptom pattern has changed.

What Do Allergy Blood Test Results Mean?

Allergy blood tests typically measure specific IgE levels against particular allergens, reported in kU/L (kilounits per litre). Results are generally categorised into classes:

Class 0 (< 0.35 kU/L): No detectable specific IgE — sensitisation unlikely
Class 1 (0.35–0.70 kU/L): Low level — possible mild sensitisation
Class 2–3 (0.70–17.5 kU/L): Moderate levels — may suggest clinically relevant sensitisation
Class 4–6 (> 17.5 kU/L): High to very high levels — can indicate significant sensitisation

It is important to understand that a positive IgE result indicates sensitisation, which means your immune system recognises and reacts to the allergen. However, sensitisation does not always equate to clinical symptoms. Some individuals may show elevated IgE levels without experiencing noticeable reactions, while others with lower levels may be significantly affected.

This is why results are most valuable when interpreted alongside your clinical history. We always recommend sharing your results with your GP or an appropriate healthcare professional to discuss what they may mean for your individual circumstances.

The London Context: Pet Ownership and Urban Allergen Exposure

London presents a unique environment when it comes to pet allergens. Smaller living spaces, reduced ventilation in flats, and the popularity of indoor-focused dog breeds like cockapoos can mean allergen concentrations build up more readily than in larger, well-ventilated homes.

According to the Pet Food Manufacturers' Association, approximately 27% of UK households own a dog, and crossbreeds including cockapoos, labradoodles, and cavapoos have seen enormous growth in popularity across London in recent years.

For Londoners living in flats or terraced housing, the combination of limited airflow, carpeted floors, and close-quarters living with a pet can sometimes contribute to higher indoor allergen levels. Private allergy testing in London can offer a convenient route to understanding your specific triggers without lengthy waiting times, complementing the support available through the NHS.

If you are based in London and would like to explore your options, you can find more information about our clinic location and services.

NHS vs Private Allergy Testing in the UK

Both the NHS and private clinics in the UK offer allergy testing, and each route has particular considerations:

Aspect	NHS Allergy Testing	Private Allergy Testing
Access	GP referral required; may involve waiting lists	Direct booking; typically shorter waiting times
Testing scope	May focus on the most clinically suspected allergens	Can often include broader allergen panels
Turnaround time	Variable depending on local services	Often faster result turnaround
Cost	Free at point of access	Fee applies — check the clinic website for current pricing
Follow-up	Integrated with NHS care pathway	Results provided for discussion with your healthcare provider

Both pathways have value, and neither is inherently better than the other. The most appropriate route may depend on your individual circumstances, symptom urgency, and personal preferences. Our clinic provides testing and reporting — we always encourage individuals to share their results with their GP or an appropriate healthcare professional for clinical interpretation and personalised guidance.

Practical Steps If You Suspect a Dog Allergy

While allergy testing can help clarify the picture, there are also practical environmental measures that may help reduce allergen exposure in the home:

Create dog-free zones, particularly in the bedroom, to reduce overnight allergen exposure
Use HEPA-filtered air purifiers in main living areas
Wash bedding frequently at 60°C or above
Bathe your dog regularly — some evidence suggests this may temporarily reduce airborne dander levels
Vacuum with a HEPA-filter vacuum rather than a standard model
Wash hands after handling your dog, especially before touching your face

Practical Insight: Environmental control measures may help reduce symptom burden, but understanding your specific allergen triggers through testing can sometimes highlight whether additional strategies are needed.
