Cover Image of the article on the Dog Dander Allergy Symptoms

According to Asthma and Allergy Foundation of America (AAFA, up to 30 percent of people with allergies are allergic to cats, dogs, and pets in general.


As we all know, we can’t deny the loyalty and affection that our pets give freely to our families.

It is, therefore, disturbing to learn that you or your kids are allergic to your family dog despite the love you may have towards it.

Nevertheless, here is the puzzling truth behind pet dander.

Contrary to the belief, it is not the pet hair that results to allergies, but rather the proteins found in their saliva, urine, and dander.

Therefore, in the article below, we will explore the pet dander allergy and explore the common dog dander allergy symptoms.

But before then, it would be prudent we have a basic understanding of what pet dander is, and how it spreads.

What is Pet Dander?

Pet dander refers to the tiny, and microscopic, flecks of skin shed by dogs, cats, rodents, birds, or other animals with fur and feather.

These bits of microscopic flecks can cause reactions, especially to people allergic to these triggers.

Because of their miniature orientation and jagged shape, dog dander can easily stick to beddings, furniture, fabrics, and a gamut of other items in your home.

Again, the pet dander is easily spread from your home and out to public places such as schools, restaurants, and hospitals, meaning you can get pet dander symptoms even if you don`t own a dog or live in a neighborhood with pets.

Besides the dog`s skin, the allergens may come from other sources such as saliva, urine, and feces.

For instance, if dried saliva containing allergens flakes off from the dog`s fur and becomes airborne, it can cause an allergy if inhaled and an individual sensitive to the triggers.

Another source can be the dried feces. That is, when it disintegrates to dust, it is much easier to be carried by wind. And in a similar manner like flakes, suspended to your homes or dog hair.

Therefore, for the pet dander, it`s important to realize that regardless of how long or short your dog`s hair is, it can potentially cause an allergic reaction.

How Dog Dander Affects You

Normally, the role of our immune system is to fight foreign substances such as viruses and bacteria and get rid of them. The above response is usually initiated to protect us against the otherwise deadly diseases and infections that would stem from the bacteria.

For individuals with allergies, however, they usually have over-sensitive immune systems, meaning they overreact, even to harmless substances like dog dander, pollen, saliva, and urine. Their immune systems often consider the pet dander as they would react to bacteria and viruses.

The signs and symptoms of pet dander such as sneezing, watery eyes, and coughing are the side effects of the body`s attempt to destroy or flush out the allergen.

So, what are the dog dander allergy symptoms?

Dog Dander Symptoms

Dog dander symptoms may range from mild side effects such as sneezing to severe risk factors such as respiratory infections or asthma. It all depends on the level of sensitivity of your immune system.

Again, the symptoms may manifest immediately, or until several days of contact with the dog dander.

As we saw earlier, a majority of the dog dander are microscopic and small enough to get into the lungs. For some, this might cause breathing problems, and to the highly sensitive individual they can begin coughing and sneezing immediately.

Alongside the coughing and sneezing is the shortness of breath within 15 to 30 minutes of contact with the pet dander allergen.

Typically, dog dander causes the inflammation of the nasal passage, consequently resulting in;

  • Swelling of the nasal membrane
  • Itching of the nasal membrane
  • Stuffy nose
  • Inflamed eyes
  • A runny nose
  • Persistent coughing
  • Frequent awakening
  • Swollen, blue-colored skin under the eyes

Risk Factors

Beyond the above dog dander allergy symptoms, constant and prolonged exposure to the dog allergen may result in a myriad of respiratory complications.

Let us look at the two major complications of dog dander allergy

Sinus infection

Chronic inflammation of the tissues in the nasal canal caused by pet allergy can result in the obstruction of the hollow cavities connected to your sinuses.

In any case, the obstruction is not only bothersome but puts you at risk of developing bacterial infections such as sinusitis.


Asthma is a chronic lung infection characterized by inflamed airways and trouble breathing.

Allergies and asthma are on a spectrum and frequency overlap because a majority of people with asthma have allergic asthma.

In most cases, asthma irritates the inflamed airways and causes the immune system to over-respond when an irritant is inhaled, thus triggering an asthma attack.

If the dog dander contributes to asthma, you may also experience;

  • Difficulty in breathing
  • Chest tightness
  • Chest pain
  • Trouble sleeping
  • Audible wheezing 
  • or whistling when exhaling

When to See a Doctor

Some of the signs and symptoms of dog dander usually overlap with the signs of common infections such as common cold.

At times, when you have a runny nose or persistently sneezing, it`s hard to distinguish whether you have a cold or an allergy.

However, if your symptoms are severe and persist for long, you should seek medical advice.

Managing Dog Pet Dander

A majority of pet owners are sensitive to multiple allergens not just from their pet. Therefore, they should focus on managing the allergens holistically, rather than addressing a dog dander allergen alone.

So, how do you manage the allergens?

  • Clean your home fanatically
  • Use air filters to purify the air
  • Restrict your dog from certain locations such as your bedroom
  • Groom and bathe your dog regularly
  • Using HEPA-certified vacuum cleaners to limit allergen levels.
  • Feed your dog with nutritious food for allergy to check production of dog proteins.
  • Distance yourself from dogs (Pets) with dander
  • If you`re to adopt a dog, choose the hypoallergenic type
  • Try owning one of the non-shedding dogs to increase the chances that it will shed dander less frequently or not at all.

Final Thought 

If you are allergic to dogs, you can not get relief from the dog dander symptoms by simply avoiding dogs. And if you are a fanatic of pets, you know how hard it is to ditch your best friend. 

That goes by saying, a majority of the allergic people will choose to make lifestyle adjustment such as maintain high hygienic levels.

Some OTC medications, such as antihistamines and nasal decongestants, are also handy in reducing or managing the dog dander allergy symptoms.

However, for those with severe and chronic dog dander allergies, you should seek medical advice so you don't jeopardize your health.
