Allergy Myths 101: Animal Allergies

There are many old wives tales or popular myths about how a person can treat their allergies.  Here at Intermountain Allergy and Asthma, we have heard them all!  As a way to help dispel allergy myths, we’ve invited Dr. Harris to share a few his thoughts in our “Allergy Myths 101” blog posts.

Two popular animal allergy myths that we hear frequently are:

  1. “The new dog couldn’t be causing my current problems because it doesn’t shed”
  2. “I grew up with animals, so I won’t be allergic to them now”

Animal allergies are a significant part of what the typical allergist deals with on a daily basis.  Here are some facts about animal allergies and suggestions to help keep symptoms under control.

Animal Allergy Fact 1: Shedding – the vast majority of the time, the animal allergens that cause problems are from the dander (tiny skin particles or flakes – think dandruff in humans), or in the animal’s saliva.  The hair or fur has little or nothing to do with it.  It may be true that a long haired cat or dog could ‘hold – on’ to more dander in the fur than a short haired animal, but whether the fur stays on the pet or is shed doesn’t matter.  All furry/haired pets have dander because they all have skin.

Animal Allergy Fact 2: Pet Saliva There are proteins in pet saliva that can cause allergies.  Some people first know that they are allergic to dogs when they get hives (welts) after being licked by the animal.  Also, cats groom themselves by licking their fur.  When you pet a cat, then rub your eyes ……  cat ‘spit’ in the eye.  Yech! 

Animal Allergy Fact 3: Exposure to animals in the past:  People develop allergies to new things all the time — including animals, plants, and foods — that they weren’t sensitive to in the past.   Tolerating pets in the past doesn’t mean that you are ‘immune’ now.

More importantly, studies have shown that some people can develop a modest amount of clinical tolerance to an animal that they are around all the time.  The allergy skin tests are still positive, but the patient’s symptoms are subdued somewhat.  In many other cases, patients become accustomed to their allergy symptoms and just ignore them, even though they are as bad as ever.  These patients can then be miserable if they leave home for a while (school, marriage, work, world travel), and then return home, or if they decide to get a new pet after years of having none.  

Animal Allergy Solutions

There are some things you can do to decrease an animal’s potential to cause allergies:  Studies have shown that frequent washing, or rinsing an animal can, in some cases, lessen the dander that is deposited around the house.  Also, keeping an indoor animal out of the bedroom, off of the bed and off any fabric-covered furniture could help as well.

Measures that can actually decrease animal allergy problems:

  • Keep furry or feathered pets outside 24/7 when conditions allow (Nobody wants to do this!)
  • If indoors, keep pets off the beds and furniture
  • Wash/rinse pets weekly
  • Get a small animal. Toy poodles should produce less dander than Great Danes
  • Keep the animal’s pelt in good condition. Treat any eczema
  • Use a HEPA air filter in your personal room – or just use good furnace filters and change them frequently (less expensive and probably just as effective)

Animal fact: Cat dander can remain suspended in the air for long periods of time after the cat has left the room.  Cat allergic people can often tell that a cat lives in a home without ever seeing the pet.

Seasonal Allergic Conjunctivitis: Pollen Allergies in the Eyes

We are fast approaching the most common time of the year for allergic problems in the eyes.  Seasonal Allergic Conjunctivitis (SAR) can occur anytime there is pollen in the air, however, for many allergy sufferers, grass pollen is more likely to cause bothersome eye symptoms than other types of pollen.  Most of the common grasses in northern and central Utah start to pollinate in late spring — when the daytime temps are in the 70’s or low 80’s.  It’s right around the corner!

What are symptoms of Seasonal Allergic Conjunctivitis (SAR)?

Symptoms of SAR include redness, tearing, and itching in both eyes, and coincide with nasal symptoms in most patients.  A number of allergy medications can (and do) help with the eyes:  antihistamines can help to some degree, as do the daily nasal sprays.  For those really bad eye days though, you’ll need eye drops in addition.   It’s OK to use antihistamines, nasal sprays, and eye drops at the same time – they won’t interfere with each other or cause unexpected side effects when used together.

If your eyes are itching somewhat, but burning, ‘grittiness’, pain, or redness are the main problems, you may have something else going on in addition to simple eye allergies.  Itching is generally the thing that patients with eye allergies complain about the most—and of course it’s often the hardest thing to control.  Rubbing an allergic eye will almost always make the itching worse – (but OH it’s tough not to rub and scratch!)  For children especially, it is just not realistic to think that they can resist the urge to rub their eyes.

How can I treat symptoms of Seasonal Allergic Conjunctivitis (SAR)?

There are a number of good over the counter (OTC) eye drops available, that will work for mild or moderate allergy symptoms.  However, be aware that some of the OTC drops are meant to be used sparingly, and can actually cause more problems in the eyes if used daily for extended periods of time.  Also, most OTC drops burn or sting for a few minutes after being used, and are not very kid friendly.  If you think that you or family members may need eye drops for much of this pollen allergy season, get in to see an Intermountain Allergy and Asthma allergist now and ask for prescription drops that can be used long term, and will be easier to use in children.

There are some types of allergic eye disease that can be quite severe, and if not treated appropriately can even affect vision long term.  If your eye symptoms are not adequately controlled with OTC meds, or if your prescription meds are not enough, make sure you let your doctor know!

Finally for those patients with significant nasal and eye allergies, and for whom medications are not enough:  allergy ‘desensitization’ shots can be very helpful with eye allergies, regardless of the type of pollen causing the problem.  Talk with an Intermountain Allergy and Asthma allergist and see if this may be a good form of treatment for you.
