If there’s one thing I’ve heard a lot, it’s that big dogs cause more allergies than small ones.
I’ve heard it from neighbors, friends, even family members who’ve never had a dog. But is that really true?
Well, as a true dog lover (and someone with allergic rhinitis), I had to find out for myself.
Before adopting my big guy — a sweet, fluffy Labrador — everyone warned me that I’d end up in the hospital because of my allergies.
So, I started digging into the topic, talking to vets, doctors, and of course, testing things myself by living with a large dog indoors.
And today, I can confidently say I understand what causes allergies and whether a dog’s size really makes a difference.
If you’ve been wondering the same thing, or know someone allergic who dreams of owning a dog, stick with me — I’ll explain everything in the simplest way possible!
What really causes dog allergies?
First of all, it’s important to understand this: it’s not the dog’s hair that causes allergies.
I was surprised too! What actually causes the reaction is a protein found in the dog’s saliva, urine, and dead skin cells, called Can f 1.
When this protein dries and spreads in the air, it can trigger allergic reactions.
And that goes for both small and large dogs.
So why do people say large dogs cause more allergies?
The logic is simple: the bigger the dog, the more skin, saliva, and urine — and more protein being produced.
Larger dogs also shed more hair and occupy more space in the house, which might spread those allergens more widely.
But listen, that doesn’t mean every large dog will cause more allergies. It really depends on how sensitive the person is.
I have a friend who sneezes just walking into a house with a poodle, and another who sleeps every night with a German Shepherd and is totally fine.
My experience with a large dog and allergies
Let me share my own experience. I have a Labrador that weighs over 30 kg (about 65 pounds), and yes — he sheds a lot.
At first, I was worried, but I set up a routine that helped me live with him comfortably, without allergy attacks.
First thing I did was keep the house clean. I vacuum almost every day, removed carpets (they trap everything), give him a bath every two weeks, brush him often, and clean his paws after walks.
Another thing that helped was getting an air purifier for the bedroom.
Sounds fancy, but it really made a difference, especially on dry days.
Oh — and a golden tip: don’t let your dog sleep in your bed or on the couch if you’re sensitive. It was hard for me to accept at first, but it made a huge difference.
Do hypoallergenic dogs exist?
Yes, they do! Some breeds are considered hypoallergenic, like poodles, bichon frisés, schnauzers, and Malteses.
These dogs either produce less of the allergen protein or have hair that traps dander better.
But remember: hypoallergenic doesn’t mean allergy-free. It just means lower risk.
So, it’s always best to spend time with the dog before bringing one home.
So… do large dogs cause more allergies?
After all I’ve learned and lived, I can honestly say: a dog’s size doesn’t define whether or not it will cause allergies.
What really matters is your sensitivity, your cleaning routine, and how you take care of the environment and the pet.
If you’ve been dreaming of having a big dog but suffer from allergies, don’t give up!
Take things slow, talk to your doctor, test it out, and keep things clean.
I’m living proof that you can live with a big fluffy dog and still breathe easy! 🐶💙
