What are the symptoms of dog allergies in humans

It is significant to see a doctor and be tested to determine what allergies you actually own. You may discover that you’re allergic to something else and not your pet at all! For example, you may assume that you are allergic to your beloved dog, only to discover out through an allergy test that you’re actually allergic to a specific tree pollen that got on his fur during a stroll together, and that’s actually what’s bothering you.

If an allergy test shows that you are allergic to your pet, it is significant to understand what causes your allergic reaction to them. There are allergy-triggering proteins called allergens in saliva and skin glands that cling to an animal’s dry skin (dander) and fur.

The fur and dander then stick to walls, carpets and clothing.

The reaction of someone to these allergens is diverse from one person to the next. The reaction may range from mild sniffling and sneezing to life-threatening asthma. The reaction can be made worse if a person is additionally exposed to other things he is allergic too, such as pollen, dust mites, cigarette smoke, and mold.

Whether someone has an allergic reaction depends on both the individual person and the individual animal.

A person with animal allergies may react less to dogs with soft, constantly growing hair, or one specific cat or dog may cause more or less of an allergic reaction than another animal of that same breed.

You may hear claims about breeds of dogs and cats that are non-allergenic (don’t cause an allergic reaction) or cats and dogs that are hypoallergenic (cause less of an allergic reaction).

However, even hairless breeds may cause a severe allergic reaction.

Sick as a Dog

For dogs, the most common clinical signs are skin inflammation and itching, Farnsworth says. Other symptoms may include sneezing and runny noses. (Take National Geographic’s dog quiz.)

Cats’ allergy symptoms can manifest as miliary dermatitis, which shows up as little scabs or missing hair, typically around the head and neck area, though it can happen elsewhere, she says.

It’s always significant to observe how endless symptoms happen in your pet—for instance, year-round symptoms may indicate a food allergy or reaction to something else in their environment that’s not seasonal.

Luckily, pets can be tested for a variety of environmental allergens—both seasonal and non-seasonal, saysChristine Cain,of the University of Pennsylvania School of Veterinary Medicine.

"We routinely test dogs for reactions to cat dander," she says.

"This includes a little quantity of allergen placed under the skin to test for reactions, just love in human allergy testing," Cain says.

Generally, veterinarians will glance for common allergens "like dust mites and human dander, or things we encounter in the environment love feathers, sheep wool, or pollens," says Washington State University’s Farnsworth.

Those are the usual suspects, but as with us, Farnsworth says, pets can be allergic to anything, and it can be hard to figure out the culprit with general testing.


Depending on the severity of your allergy, you may be capable to make a few adjustments that can prevent and alleviate your symptoms.

Strategies that can assist prevent your symptoms include keeping your dog clean, vacuuming dog hair, and making certain that there is no dog urine and feces inside your home.

The substances that cause allergic reactions are allergens.

Pet allergens can collect on furniture and other surfaces. The allergens will not lose their strength for a endless time. Sometimes the allergens may remain at high levels for several months and cling to walls, furniture, clothing and other surfaces.

Pet hair is not an allergen.

It can collect dander, urine and saliva. It also can carry other allergens love dust and pollen.

Respiratory or asthma symptoms can be treated with inhaled corticosteroids or bronchodilators to either prevent or relieve respiratory symptoms.

Allergy shots (immunotherapy) are an effective treatment of allergies by building tolerance over time through gradually injecting increasing doses of an allergen.

Is there an allergy-free dog?

While poodles, Portuguese water dogs and a number of other breeds (including several types of terriers) own a reputation for being hypoallergenic, a truly allergy-free breed does not exist.

What are the symptoms of dog allergies in humans

A 2011 study compared dust samples from homes with dog breeds reported to be hypoallergenic and those of homes with other dogs. The levels of dog allergen in homes with “hypoallergenic” dogs did not differ from the levels in homes with other breeds.

Pet Allergy: Are You Allergic to Dogs or Cats?

Allergies to pets with fur are common, especially among people who own other allergies or asthma. In the United States, as numerous as three in 10 people with allergies own allergic reactions to cats and dogs. Cat allergies are about twice as common as dog allergies.

Cat and dog allergens can land on the membranes that line the eyes and nose.

Reactions include swelling and itching of the membranes, stuffy nose and inflamed eyes. A pet scratch or lick can cause the skin area to become red. It is common to get itchy eyes after petting an animal then touching your eyes.

If allergen levels are low or sensitivity is minor, symptoms may not appear until after several days of contact with the pet.

Many airborne particles are little enough to get into the lungs. For some, this exposure can cause severe breathing problems. Highly sensitive people can start coughing, wheezing and own shortness of breath within 15 to 30 minutes of inhaling allergens. Sometimes highly sensitive people also get an intense rash on the face, neck and upper chest.

Medical ReviewOctober 2015.

Spring has sprung,and with it the return of warmer weather, longer days, and one decidedly unwelcome guest: allergies.

It’s also the perfect season to turn the tables and glance at allergies from our pets’ point of view.

So for Weird Animal Question of the Week, we’re responding to National Geographic’s own Emily Tye, who asks: "Can cats be allergic to dogs, or vice versa?"

We also wonder—can they be allergic to us?

"The answer to every of these is yes," saysRaelynn Farnsworth, of Washington State University’s College of Veterinary Medicine. (See "Coughing Cats May Be Allergic to People, Vets Say.")

"It’s rare, but dogs can be allergic to cat dander and people dander and vice versa.

For everything."

Dander is made up of tiny cells shed from hair, fur, or feathers—and though you mostly hear it in relation to pets, humans produce it, too. Other common pet allergies include flea saliva and certain foods.


A dog allergy can affect children or adults. This type of allergy can trigger a variety of effects, including respiratory symptoms and skin reactions.

You may start to notice a pattern of symptoms that occurs whenever you spend time with dogs or with a certain dog. Clothes, furniture, carpet, or other materials that a dog came in contact with can trigger an allergic reaction as well.

Symptoms of a dog allergy generally start within an hour of exposure.

They can final anywhere from a few minutes to endless after the pet is gone, since its dander can remain in the air, on the furniture and on your clothing.

Common symptoms of a dog allergy include:

  1. Coughing
  2. A sore throat
  3. Itchy skin
  4. Sneezing
  5. Itchy, runny, or stuffy nose
  6. Red, itchy, or watery eyes
  7. A skin rash (it can be anywhere on your skin, not just on the area of direct contact)

Asthma can be exacerbated by dog allergies. You or your kid may own an asthma attack, characterized by wheezing and shortness of breath when exposed to dogs.

Dog-Induced Symptoms Unrelated to Allergies

Keep in mind that a dog allergy should not cause fevers, abdominal pain, vomiting, diarrhea, skin wounds, blisters, or swelling.

Dogs can transmit other illnesses to humans that cause effects diverse from those of allergies.

Some people experience severe anxiety when around dogs—this is a phobia and not an allergic reaction.

It’s Not Me, It’s You

So what if your pet is allergic to you?

"It always makes owners helpful of unhappy if their reaction is to human dander," Cain says, but happily the two of you don’t own to part.

(See "Why Do We Get Allergies?")

"If we own a patient that reacts to human dander, generally they react to other allergens as well," she says.

That means your vet can treat the pet’s allergy, either with allergy shots or oral drops that contain little amounts of the problem allergens. This retrains your pet’s system to ignore the allergen.

Of course, the cat might always be faking an allergy in hopes you’ll get rid of the dog.

Millions of people enjoy sharing their homes and their lives with pets, even those who are allergic to animals. Unfortunately, some people believe that once they are diagnosed with a pet allergy, they own no choice but to remove their pets from their family.

Thankfully, there are numerous solutions that can be explored that would permit an allergy sufferer to hold their beloved pets while successfully managing their allergies.

You’d be surprised to know how numerous people with allergies that aren’t life-threatening are capable to live happily with their pets.

In numerous cases, the benefits of having a pet outweigh the drawbacks of pet allergies.


Your allergy can be triggered by dog fur, saliva, urine, feces, vomit, blood, or dander.

What are the symptoms of dog allergies in humans

Pet dander is extremely little material shed by pets, and it is composed of dead skin cells. Dander may lodge in fabric, triggering an allergic reaction even when the pet is not in the same room.

A person can be allergic to every dogs or to certain dog breeds. While some breeds of dogs are marketed as being hypoallergenic, there is no evidence to support this claim. In fact, researchers found that the quantity of allergens in homes with supposedly hypoallergenic dogs was no diverse from homes with dogs that are generally considered to be non-hypoallergenic. Anecdotally, dogs with certain characteristics—non-shedding coats, short hair, little size—are reported to be less allergenic.

But there is no way to be certain you won't be allergic to a specific dog other than to spend plenty of one-on-one time with the animal before buying or adopting it.

Immune Reaction

A dog allergy occurs due to dog allergens that induce an inflammatory reaction. An allergen is a harmless substance that triggers the body's immune system to react as if there were an infection.

The major dog allergen, Can f 1, is primarily found in dog saliva. Can f 2, Can f 3, Can f 4, and Can f 6 are found in dog fur. Dog albumin, another allergen, is a protein found in the blood.

With a dog allergy, one or more dog allergens trigger the activation of white blood cells and an antibody product called immunoglobulin E (IgE).

IgE induces more inflammatory cells, such as basophils, and proteins that cause the physical responses experienced during an allergic reaction. This is a temporary reaction, lasting between a few minutes to a few hours. But recurrent or constant exposure to the allergens can make the reaction final for a while.


It can be extremely hard to diagnose a dog allergy. Not only are dog allergies less common than cat allergies, but other health problems caused by dog exposure are also much more common than dog allergies are.

If you notice that your symptoms start during or after exposure to a dog, be certain to talk to your doctor.

You may need to own a blood test to measure your IgE levels, or a skin prick test to check your reaction to dog allergens.

Blood and Skin Testing For Allergic Reactions

There are a number of other health issues that you can develop due to dog exposure, and the management of these health issues differs from the management of dog allergies.

Conditions you can get from dogs include:

  1. Fleas: Dogs can own fleas and may transmit them to humans. Fleas are tiny insects that can bite your skin, especially under your hair. They can cause itching and red spots on your skin.
  2. Poison ivy: This is a rash caused by a hypersensitive reaction to the poison ivy plant.

    This rash is triggered by touching the plant or coming into contact with oil from the surface of the plant. Poison ivy causes an itchy, red, blistery rash that can develop anywhere on your body (including the eyes). While it is rare for dogs to react to poison ivy love humans do, you can get this rash by coming into contact with the plant's oils on your dog's skin or coat.

  3. Gastrointestinal (GI) infections: There are a number of GI infections that you can catch from coming into contact with a dog's feces.

    If the infectious microorganism (usually a bacteria, virus, or parasite) gets into your mouth, you can become extremely ill. These infections can cause stomach aches, vomiting, diarrhea, muscle aches, and fevers. Giardia, salmonella, and cryptosporidium are examples of infections you can catch from a dog.
