Allergies to dogs are more common than many pet owners realize. For those affected, the joy of being around a furry friend can quickly turn into sneezing fits, itchy eyes, or a runny nose. These symptoms can make daily life uncomfortable — and in some cases, even limit social activities or interactions with loved ones who own pets.
The good news? You can manage dog allergies effectively with the right combination of medical treatment, lifestyle adjustments, and allergen-reduction strategies. Whether you’re living with a dog or frequently visiting homes with pets, there are proven ways to reduce symptoms and improve your quality of life.
In this guide, we’ll break down everything you need to know — from understanding the science behind canine allergies to practical tips you can start using today.
What Causes Allergies to Dogs?
Dog allergies are triggered by specific proteins found in:
- Dander: Tiny flakes of skin that dogs naturally shed
- Saliva: Transferred when dogs lick themselves (and then shed dried saliva into the air)
- Urine: Particles can become airborne or remain on surfaces
When a person with dog allergies comes into contact with these proteins, their immune system reacts as if it’s under attack. This immune response releases histamines, leading to symptoms like sneezing, congestion, and itchy eyes.
Important note: It’s not the dog’s fur that causes allergies — it’s these proteins. This is why even “hypoallergenic” dog breeds can still trigger symptoms.
Common Symptoms of Dog Allergies
Symptoms can range from mild and seasonal to severe and year-round. Common signs include:
- Sneezing, nasal congestion, or a runny nose
- Itchy, watery, or red eyes
- Coughing or wheezing
- Skin rashes or hives after contact
- Postnasal drip and sinus pressure
If your symptoms consistently appear after spending time around dogs, it’s worth speaking to an allergist for a professional diagnosis.
Diagnosing Dog Allergies
An accurate diagnosis ensures you treat the real cause of your symptoms. Your allergist may recommend:
- Skin Prick Test – A small amount of dog allergen is introduced under the skin to check for a reaction.
- Blood Test – Measures your immune system’s response to specific allergens.
Getting tested helps rule out other allergy triggers (such as dust mites or mold) and allows for a personalized treatment plan.
Reducing Dog Allergens in Your Home
If you live with a dog, complete avoidance isn’t realistic — but allergen reduction is possible.
1. Create Allergen-Free Zones
Keep at least one room (ideally your bedroom) completely pet-free. This gives your body a break from constant exposure.
2. Upgrade Your Cleaning Routine
- Vacuum frequently using a HEPA-filter vacuum to capture fine particles.
- Wash bedding, curtains, and rugs regularly in hot water.
- Wipe down hard surfaces with a damp cloth to trap dust and dander.
3. Bathe and Groom Your Dog
Bathing your dog once or twice a week (with vet-approved shampoo) can reduce allergen levels. Brushing outdoors also prevents loose dander from settling indoors.
4. Improve Air Quality
An air purifier with a HEPA filter can trap airborne allergens, making your indoor air cleaner and easier to breathe.
Medical Treatments for Dog Allergies
For many, lifestyle changes alone aren’t enough. Medical treatment can provide the relief needed to comfortably live with or around dogs.
Over-the-Counter Medications
- Antihistamines – Reduce sneezing, itching, and runny nose.
- Nasal Corticosteroids – Help control inflammation and congestion.
Prescription Medications
- Leukotriene Modifiers – Block allergy-causing chemicals in the body.
- Stronger Corticosteroids or Combination Therapies – For severe cases.
Immunotherapy (Allergy Shots or Drops)
This long-term treatment gradually trains your immune system to tolerate allergens. Sublingual immunotherapy (SLIT) — allergy drops placed under the tongue — can be especially effective for pet allergies without the need for injections.
Natural and Lifestyle Remedies
- Saline Nasal Rinses – Flush allergens from nasal passages.
- Omega-3 Fatty Acids – May help reduce inflammation in the body.
- Regular Exercise – Supports immune function.
- Stress Management – Techniques like yoga or meditation can help reduce allergy flare-ups triggered by stress.
Creating Your Personal Allergy Action Plan
Life is unpredictable, and dog encounters can happen anytime. Prepare by:
- Keeping antihistamines in your bag or car.
- Informing friends and family about your allergies so they can help minimize exposure.
- Having a quick-clean routine for your home after high-exposure events.

FAQ: Dog Allergies
Can you be allergic to some dogs but not others?
Yes. All dogs produce allergens, but the amount varies by breed and individual. Some people react more strongly to certain breeds.
Do hypoallergenic dogs really exist?
No breed is completely hypoallergenic. Some shed less dander, but the allergen proteins still exist in saliva and urine.
Can dog allergies go away?
Some children may outgrow certain allergies, but for most people, dog allergies are lifelong. Treatments like immunotherapy can significantly reduce symptoms.
Are allergy drops as effective as allergy shots?
Yes. SLIT (allergy drops) is clinically proven to reduce symptoms and is a convenient, needle-free option you can take at home.
Managing dog allergies isn’t about choosing between loving dogs and feeling healthy. With the right strategies — from allergen reduction and medical treatment to personalized care from an allergist — you can enjoy life with fewer symptoms and more time with your furry friends.
