Dog Owners Guide To Dog Allergy Symptoms


Dog allergy symptoms can be caused by a variety of different factors – on this page we will start with how humans can be allergic to dogs (and the symptoms that they might experience) and also the symptoms that a dog might exhibit if he or she experiences an allergic reaction.

Human allergies to Dogs

It is actually quite common for humans to be allergic to certain breeds (bear in mind that over forty percent of families in the United States own a dog).

Studies have shown that in every home in the United States there are some signs of dander even when a pet has not actually lived. Dander are the dead skin cells that fall off your pet. Some people get confused and believe that it is the shedding of hair that causes the allergy symptoms but it is the dander, saliva and urine that causes the problems.

When a person is experiencing an allergic reaction they might sneeze, start itching, cough, wheeze, have a runny nose and runny itchy red eyes.

It is also possible that if a dog licks your arm or face that your body reacts negatively to the saliva – this might cause more extreme symptoms including hives or a skin rash. People that already have an existing health condition like Asthma are more vulnerable to developing a reaction.

What causes allergies to dogs?

As previously mentioned it is not the fur or hair that causes the signs and symptoms of an allergy it is the dead skin cells (dander), saliva and urine that causes the problems. In fact it does not actually matter if your dog has short hair or long hair as this is a misconception – either type can cause negative symptoms as it is not the shedded hair that causes the problem but the dander (flakes of dead skin cells).

Dog allergy symptoms are actually caused by the human body and immune system trying to eliminate the cause by attacking it as if it was a foreign body like a parasite, bacteria or virus. And the symptoms of sneezing, watery eyes, itching etc is a human’s way of trying to get rid of the allergen.

How are allergies to dogs in humans tested?

The normal testing procedure for a person suspected of experiencing dog allergy symptoms is through a RAST test (a skin test referred to as a Radioallergosorbent test).

However, tests for allergies to dogs is not always conclusive and your GP may request that to determine whether it is your dog that is causing the allergic reaction (rather than something that your pooch has carried in from outside) is for you and your dog to spend some time apart. This will help your Doctor to conclusively determine whether it is your dog causing the problems or something else.

Treatment for Dog Allergy Symptoms in humans

The most common treatment for dog allergies is through the antihistamines and decongestants. Most of these treatments you can get from your local pharmacist.

It is always a good idea to reduce the chances of developing an allergy to dogs by making sure that your home is dander free (this is a difficult task but it can be achieved if you vacuum everywhere and wash and clean all areas). Normal vacuum cleaners will not collect all of the allergens so you should purchase one that has a HEPA filter.

Try and keep your pets out of your bedroom – this is the place where you spend most of your time so will reduce the chances of you developing an allergic reaction.
