FAQs: All you need to know about your dog allergy

With over 12 million dogs sharing our homes and communities, it’s no surprise that dog allergies are on the rise. Unfortunately, many cases of dog allergies go undetected, leaving individuals unaware and untreated. The tiny allergen particles from dogs can quickly become airborne and find their way into various environments, making dog allergies a widespread issue.

This is particularly concerning among children. Schools have become hotspots for allergen accumulation. Even without dogs present on the premises. For adults, it’s the same story. The rise of dog-friendly spaces, such as offices, restaurants, and public transport, increases exposure.

Understanding dog allergies is more crucial than ever, whether you’re a pet owner or find yourself sharing spaces where dogs have been. We wanted to take you through some of the frequently asked questions about dog allergies.

What is a dog allergy?  

A dog allergy is an allergic reaction to one or more of the allergens produced by dogs. These allergens can be found in a dog’s hair, dander, saliva, and urine. When people with dog allergies come into contact with these allergens, their immune systems can react, causing symptoms like sneezing, itching, or more severe respiratory issues.

How common are dog allergies?

Dog allergies are pretty common worldwide, and the prevalence has been increasing over recent decades. A significant number of both children and adults exhibit allergic sensitisation to dogs, which can be a risk factor for conditions like asthma and rhinitis.

What causes dog allergies?

Dog allergies are triggered by proteins known as allergens found in the dog’s skin cells (dander), saliva, urine, and even hair. These proteins can bind to antibodies in the immune system of allergic individuals, leading to an allergic reaction.

What are the symptoms of a dog allergy?

Symptoms of a dog allergy can range from mild to severe and include sneezing, runny or stuffy nose, itchy or watery eyes, skin rash, coughing, chest tightness, shortness of breath, and wheezing. In highly sensitive individuals, exposure to dog allergens can exacerbate asthma symptoms.

How do dog allergens spread?

Dog allergen particles are tiny, light, and can become airborne quickly. They can be carried on clothes, circulate through air systems, and settle in household dust, making them pervasive even in environments where dogs are not present.

Are some dog breeds hypoallergenic?

No dog breed is truly hypoallergenic. While some breeds are marketed as producing fewer allergens, all dogs produce allergenic proteins. The difference lies in the amount and type of allergens they produce, which can vary by breed, age, and individual dog.

Can I live with a dog if I have a dog allergy?

Living with a dog can be challenging for someone with a dog allergy, but it’s not impossible. Strategies like maintaining strict cleanliness, keeping the dog out of certain areas (like the allergic person’s bedroom), and using air purifiers can help reduce allergen levels. Regularly washing the dog and any items it frequently contacts can also reduce allergens.

Can dog allergies lead to other health problems?

Yes, allergic sensitisation to dogs can be a risk factor for developing asthma and rhinitis. For those already with asthma, exposure to dog allergens can lead to poorer lung function and an 

increased frequency of asthma attacks.

Is an end to dog allergies in sight?

Is an end to dog allergies in sight?

For any animal lover, a dog allergy is as bad as it can get. Missing out on cuddling up to a furry friend isn’t a prospect many like the sound of. But for some people, it’s their reality. As many as 3 in 10 people could have an allergy to dogs (and cats). And it’s common in people who already have allergic asthma or hay fever.

But researchers in Japan might have laid the groundwork for an answer to people’s dog allergy woes. One preliminary study shows positive signs for creating a dog allergy vaccine. While we’ll stress it’s very early days, it could be promising. Let’s look at what they’ve been up to.

The research

Towards the end of 2021, researchers published their early findings in the Federation of European Biochemical Societies journal. Now, before we dive into it, it’s worth mentioning that there are actually seven types of dog allergens – the molecules that cause an allergic reaction. So finding one single “cure” isn’t simple.

But one particular allergen – “Can f 1” – causes the majority of allergic reactions to dogs. Meaning figuring out an answer to this one could help a lot of people. The problem is that not much is known about its structure. Specifically, its ‘epitopes’ – the part that is recognised by our immune system and leads to an allergic reaction.

So the research so far has involved a process called “X-ray crystallography”. This has been used to shed some light on the structure of Can f 1 and, hopefully, narrow down where this epitope is on it.

The results

Through the X-ray crystallography, the researchers found some similarities to other dog allergens. But the key is in the differences they found in the electrical charges. This could lead them to some good candidates for the epitope.

What’s next? Further research is needed to narrow the candidates down, but it’s still a big step forward. The ultimate goal is to create a vaccine that introduces small amounts of the allergen into the system – no different from any other vaccine.

Talking about the work, Takashi Inui – a specialist in allergy research and lead author on the study – had this to say: “We want to be able to present small doses of these epitopes to the immune system to train it to deal with them, similar to the principle behind any vaccine. But we can’t do this without first identifying the Can f 1’s IgE epitope.”

In reality, what they find could mean a lot for many allergies, not just dog allergies. But that’s well in the future. For now, we’ll have to learn to live with our allergies and continue to look after our health. One day, though, we might be able to truly live in peace.

You can’t wait for an allergy vaccine, so don’t leave yours untreated. Our allergy specialists can help you cope with any sensitivities you may have and give you the best advice to stay safe. Register as a new patient here or call us on 02031 433 449.

Q&A: What to do when you find out you’re allergic to your dog

Q&A: What to do when you find out you’re allergic to your dog

Plenty of people in the UK love their pets. It could be a cat that lazes around the house all day, a bird that sings to them, or a lizard bathing itself under a heat lamp. By far the most popular pet is man’s best friend – the dog. It’s estimated there are about 9 million dogs in the UK and with the lockdown, there’ll be plenty more.

But what happens when you realise you’re actually allergic to your new furry friend? We’re here to answer your questions about what to do if you’re allergic to your dog.

Can I keep my dog?

The first question on many people’s minds will be whether they can keep their loyal companion. The answer is, usually, yes – if you’re prepared to live with the consequences. The advice from doctors would probably be to bite the bullet and find a new home for them. It won’t be easy, but it will help you live easier.

I don’t want to give them away. What else can I do?

If you really don’t want to part ways (and we can easily understand why), there are precautions you can take to minimise allergic reactions. Keep windows open to stop a build-up of pet dander, the culprit that usually causes your reactions. Stay on top of your cleaning schedule, vacuuming daily around areas your dog spends time. Don’t let them on furniture such as beds and sofas.

Also, talk to your doctor. They may have more advice or be able to prescribe medication to ease your symptoms.

Could something else be causing my allergy?

There is a chance it might not be your dog. If they spend a lot of time outside, they might be bringing pollen in on their hair, aggravating your hay fever. They may even have some hitchhikers, and your allergy is to the mites instead. Regularly washing your dog and watching where they go can help with this.

What if I don’t have a dog yet? Can I still get one?

If you know you’re allergic to dogs and still want one, definitely give it some consideration. Ask yourself if potentially having symptoms every day is worth it. If you still want a dog, there are some that might be better for you. Those that shed less, thus leaving less pet dander, might help. Though keep in mind that no dog breed is truly ‘hypoallergenic’ – i.e. completely allergy-free.

How can I be sure I have a dog allergy?

The only way to be 100% sure is to have a doctor or allergy specialist test you for allergies. Through one of many methods, they can help uncover what allergies are holding you back. When you want medical advice, this should be your first port of call.

We know the choice between your health or your pet can be a tough one. But you should put yourself first and find a solution that works for both of you.
