There’s no doubt that we love our furry friends. According to the American Pet Products Association, about 67% of American homes have a pet.
But what happens when someone is allergic to dogs? The American College of Allergy, Asthma, and Immunology estimates that up to 10% of Americans have a dog allergy. Just what causes the allergic reaction, and is there anything we can do to manage the allergy?
Let’s start at the beginning, with dog dander and its role in dog allergies.
Most people think that a dog’s hair or fur causes allergies, but that’s not the case. The allergic response is a reaction to minute protein particles left on the skin from sweat, urine, or saliva. Each day, your pooch sheds flakes of old skin, and this sloughed skin is known as dander.
Because it comes from skin flakes, dander looks like tiny flecks of dandruff or household dust. The problem is these particles can be microscopic in size and hard to see.

How does it Spread?

The short answer is that it flies. Dog dander is all over the place; it can even be in homes that don’t have pets. That’s because the tiny particles take to the air before they settle on furniture, floors, and other surfaces. According to WebMD, 90% of US households have detectable levels of pet allergens.
Dander can also land on your clothing. According to the American Lung Association, the allergens in dander are very sticky and will adhere to fabrics. That means you may unknowingly carry the particles with you when you leave the house.
The allergen proteins can linger for a long time in your home without losing strength. According to the National Institute of Environmental Health Sciences, the particles can circulate in a home for months.

Understanding Dog Allergen

Scientists have identified seven distinct dog protein allergens from two protein families:
Some of the proteins are in your dog’s saliva. The most common pet allergen is a lipocalin called Can f 1. About 70% of people with a dog allergy have a sensitivity to this protein. It comes from the epithelial cells in the tongue and passes to the dander through saliva. When your pooch licks his fur, the protein transfers to his skin and hair.
Normally, the immune system identifies foreign invaders like viruses or bacteria and works to eliminate them. However, some people have extra sensitivities to harmless substances such as dog allergen proteins that are found on dander. When airborne particles land on the mucous membranes in the nose or around the eyes of these individuals, it triggers the immune response that causes an allergic reaction.
Because we inhale dander or contact it in the environment, allergy symptoms usually show up in the skin or respiratory tract and can include:

Recognizing Pet Allergies in Children

If you have children and you’re introducing a dog to the home, how will you know if they have a dander allergy versus another allergy or a simple cold?
In the case of pet allergies, the symptoms will be present year-round, not just for a few weeks or during certain seasons. There could also be environmental allergens causing the symptoms, like mold or mite allergies.
First: kids’ symptoms are similar to adults:
To help figure out whether Fido is the source of your child’s allergic response, observe them before and after they spend time playing with your furbaby to see if there are any reactions. If you think your kid has a pet allergy, an allergist can run tests to confirm your suspicions.

Dog Dander as an asthma trigger

For many, a pet allergy is an inconvenience or a nuisance. But sometimes, the reactions are more severe. If you suffer from asthma, pet dander may also trigger:
Pet owners with asthma need to be extra diligent when managing pet dander in the home.


In addition to dander allergies contributing to asthma, untreated symptoms can lead to health complications like:
When it comes to symptoms, the common cold and allergies have a lot of similarities. Before you blame the dog, let’s take a look at how the two conditions compare:

Cold Symptoms

Allergy Symptoms

It can be hard to tell if you have a cold or an allergy. One difference between the two is how long the symptoms persist. A cold virus generally lasts a few weeks, but allergies can be seasonal or year-round. With that in mind, contact your doctor if your symptoms
A medical professional can evaluate your symptoms and run diagnostic tests to determine their cause.
If you suspect that you’re allergic to dander, talk to your doctor about testing before you make any drastic lifestyle changes (like rehoming Fido). You might find out that something else in your environment is triggering your immune system. When it comes to pet allergies, there are two general types of tests available: skin and blood.

Blood Testing

If your symptoms are severe, you have a skin condition that could interfere with test results, or you’re taking certain medications, your doctor may need to use a blood test. This type of screening checks your blood for antibodies to allergens. It is more expensive and can be less sensitive than skin tests, so it’s usually not the first choice of allergists.

Skin Testing

With skin testing, your doctor can check you for sensitivity to a range of different allergens. This is the preferred approach because it’s easy, less expensive than blood tests, and allows for a broader screen. There are three ways to do a skin test.
Treatments for Dog Dander Allergies
If you have an allergy to dog dander, that doesn’t mean all is lost. There are treatment options available that may be able to help you manage your symptoms enough to live with a pup. Let’s take a look at the dog dander allergy treatment options that are available.

One treatment option for people with allergies is immunotherapy or allergy shots. With this approach, a certified allergist will perform a screening test to identify substances that trigger a patient’s allergic response. After the results are in, the allergic individual will receive a series of serum injections that contain small quantities of the allergen. Over time, the body’s immune system will build a tolerance to the substance and stop triggering an allergic reaction. Usually, the process takes 3-5 years.

Nasal and Oral Corticosteroids

Corticosteroids help reduce inflammation and swelling in the nasal passages to ease allergy symptoms. They can be highly effective to treat congestion, itching, sneezing, and runny nose, but you’ll need to take them regularly. These products are available as nasal sprays, inhalers, pills, and liquids. Some examples include:

Oral Antihistamines

When an allergen triggers the immune response, the body releases histamines. The histamines cause inflammation and lead to allergy symptoms like itchiness, sneezing, runny nose, and more. One way to combat the allergic cascade is by taking an oral antihistamine to block the response. Use a non-drowsy, 24-hour antihistamine to manage your symptoms. A few examples of oral antihistamines include:

Natural Remedies

Essential Oils

Essential oils can be used alone or in combination with OTC medications to help reduce inflammation and allergy symptoms. There are several oils that can help manage a pet dander allergy. For example, lemon and lavender oils have antihistamine properties while peppermint and Roman chamomile essential oils yield anti-inflammatory effects.

If you have a dog allergy, all is not lost. There are ways to live with Fido and manage your symptoms. Consult an allergist to learn about dog dander allergy treatment options that can minimize or alleviate the allergic response. In addition, you can take steps to keep dander down in your home.

Step 1: Dog Care Tips


Regular grooming practices help to remove dead and flaking skin in a controlled environment. Brushing, bathing, and clipping the hair short can reduce the amount of dander your pup sheds.
A dog shampoo for dander  like this one from Allerpet can help condition Fido’s skin to keep it healthy. Apply this type of product after brushing your pal.


What? My dog’s diet can affect how much dander he sheds? Yes! If your pooch has a food sensitivity, it can cause him to itch and scratch more frequently. In addition, a lack of certain supplements, like Omega 3 and 6 Fatty Acids may contribute to dry skin and flakiness. If you notice Fido chewing, licking, or scratching a lot, talk to your veterinarian about whether he needs a change of diet.


Just like some food sensitivities cause your dog to shed more dander, some supplements help to reduce dander. The main nutrients that support your pup’s skin and hair are essential fatty acids. Omega 3 and 6 Fatty Acids help to prevent dry, flaky skin that produces more dander. You can add ingredients like fish or coconut oil to Fido’s diet to promote healthy skin.

Reducing Dander Output

There are some underlying skin or medical conditions that can affect the amount of dander that Fido sheds. If your pal has a food sensitivity or allergy to something in his environment, it often results in more dry, flaky skin cells. Another cause of skin irritation is parasites like fleas and mites. Treating underlying issues may help reduce dander output.
If you see signs like:
contact your veterinarian for an evaluation.


Vacuum your furbaby’s bedding weekly. You can also use removable covers that are easy to launder. Remember to wash any blankets and washable toys as well. This will help reduce the level of loose dander and dried saliva.

Personal Hygiene

Wash your hands with soap and water after petting, kissing, or playing with your dog. When you spend an extended time handling Fido, you should change and launder your clothes as well. In some cases, you may need to shower after contact with a pooch.

Step 2: Environmental Care Tips

Use a HEPA Filter

HEPA filters like the Levoit Air Purifier can remove microscopic particles like dander from the air. These specialized filters trap 99.97% of contaminants that are 0.3 microns or larger. In addition, the filters use a pre-filter and carbon filter to provide improved air quality in your home.

Clean Your Carpets and Rugs Weekly

It’s important to vacuum rugs, carpets, and furniture weekly. You may also want to consider washing or vacuuming drapes and stuffed animals. There are several quality cleaners on the market that have a HEPA or premium secondary filter to help you remove as much allergen as possible. Because the vacuuming process can stir up dander and allergen particles, try to clean when allergic family members are out of the house. In addition to a weekly routine, plan regular steam cleaning of your carpets.

Make Your Home Easier to Clean

You can make your job easier by replacing upholstery, rugs, and carpets with washable surfaces like hardwood or tile. Dander sticks to fabrics and rugs more easily than hard surfaces. If you must have a carpet, get one with a low pile to minimize dander build-up.

Keep Fido Out of the Bedroom

It’s sad but true. The last place you want your furbaby at night is snuggled by you in bed. If you have an allergy to dander, you’ll breathe easier and sleep better if your bedroom is a pet-free zone.

Create an “Allergy Free” Zone

In addition to the bedroom, you can restrict your four-footed friend from other parts of the house. Confine Fido to one or just a few rooms and keep them outside as much as possible to minimize dander. You can also use HEPA filters and regular cleaning in pet-free areas to remove as much stray dander as possible.
Owning a Dog May Help Protect Children From Allergies
For years, people feared that exposing a baby or toddler to pets might make them more prone to allergies later in life. But recent studies suggest that the opposite may be true.
These are a few examples of recent research, and the results are promising for dog lovers. It appears that early exposure to a furbaby has positive health effects that include reducing the risk of allergies.
Hypoallergenic Dogs
Perhaps you’ve heard the term, “hypoallergenic dog,” but what does it mean? According to Bernadine Cruz, spokeswoman for the American Veterinary Medical Association, “dogs that are more universally less allergenic come from more specific breeds.” So what causes the difference?

What Makes a Dog Hypoallergenic?

Because dander often attaches to pet hair, breeds that don’t shed tend to produce less of the floating particles. Non-shedding pups also have regular visits to a groomer for hair cuts and bathing. These activities also help to minimize dander.

Are Hypoallergenic Dogs Completely Allergen-Free?

Is there really such a thing as a 100% hypoallergenic dog? Not really. Some people can have an allergic reaction even with a so-called hypoallergenic dog. In most cases, however, there are breeds that tend to create less dander and can work well for people with allergies.

What Are the Best Dogs For People With Allergies?

If you have a pet dander allergy but want to have a four-footed friend, your best bet may be a non-shedding dog. Here are some of the breeds that the American Kennel Club recommends:
