True or False: Pet Allergies Quiz


            The sensitivities that we know today as allergies were first recognized thousands of years ago by prominent Greek physicians of the ancient world such as Hippocrates and Galen.  By the mid 1500s, Italian physician Pietro Mattioli recorded symptoms of a patient suffering from “cat fever,” in what may be the first specific reference to pet allergy.  He noted that the patient suffered agitation, sweating and pallor in the presence of the cat, and reacted the same way even when the cat was concealed from him.   
Scientific understanding of our immune system and what causes an allergic reaction is still rather recent, so it’s not surprising that myths about pet allergies abound.  Some are true; others are totally incorrect and frequently influence our attitudes and knowledge about dealing with sensitivities to pets.  How many of these common beliefs about pet allergies can you identify correctly as true or false?

1. A pet's hair or fur causes allergies.

2. Shorthaired dogs and cats may trigger fewer allergies than longhaired ones.

3. Kittens and puppies cause fewer allergy problems than adult pets.

4. You can be allergic to some breeds of dogs and cats and not to others.

5. You can become desensitized to your pet.

6. Dogs that shed excessively cause more problems for allergy sufferers.

7. Poodles, Bichon Frises, Maltese and certain other purebreds are good choices because they shed little or no hair.

8. Cornish, Devon Rex and Sphynx cats are hypoallergenic because they don't shed hair.

9. Black cats trigger more allergies than other colors.

10. Some bird species can trigger more allergy symptoms than others.

11. Rabbits do not cause allergies because they are very clean animals.

12. Rodents and other small furry pets are recommended for allergy sufferers.

13. You can't ride horses if you are allergic.

14. Pets that live outdoors cause fewer allergy problems.

15. Restricting a pet to one or two rooms of your house will make it easier to tolerate.

16. You can be more allergic to your pet in the spring and fall.

17. You can be allergic to clothing and furnishings made from animal fur or feathers.

18. People who are allergic to their pets must find new homes for their animals.

 

Answers

  1. False.  Allergic sensitization to pets is caused by dander, sebaceous skin gland secretions, saliva, and urine, not by hair or fur.
  2. True.  Although all dogs and cats – hairless, shorthaired, longhaired, wire-haired, curly-haired and even hairless – can trigger an allergic response, the shorter hair shafts of shorthaired breeds usually carry less dander.      
  3. True.  Baby animals have much less dead skin to shed and consequently little dander.  They usually do not produce allergens in sufficient quantities to cause major sensitivities.  However, from birth up to six weeks, while baby animals are nursing, they may temporarily be coated with more allergens due to their mother’s licking and cleaning, and from the excessive amounts of urine in their whelping box.  
  4. True. Your tolerance level or sensitivity will not necessarily be the same to all breeds of dogs or cats. There can be significant variations even within a specific individual breed.  For example, researchers at the Mayo clinic found that some cats shed one hundred times more allergens than others. 
  5. True.  Many individuals can live comfortably with their own pets, but experience symptoms outside of the home, probably due to natural desensitization, related to years of exposure to their pets.      
  6. True. All dogs shed, but double-coated breeds, like Akitas, Collies, German Shepherd Dogs, Samoyeds, Shetland Sheepdogs, seem to cause more sensitivities than others.  They have two kinds of hair: a thick outer coat and a softer undercoat.  They can shed excessive amounts of hair, contaminated with allergens, throughout the home, especially during peak shedding seasons in late spring and early fall.  
  7. True.  No dog – purebred or mixed-breed – is truly hypoallergenic.  However,    Poodles, Bichons Frises, Maltese, Kerry Blue, Bedlington and Soft-Coated Wheaten Terriers, Portuguese Water Dogs and other breeds with soft, silky or curly single coats, seem to be less allergenic. They have no undercoat, consequently they shed very little.  Instead of finding hair throughout your house, it stays in the coat until it’s brushed or combed out.  Keep in mind, too, that many of these breeds require regular professional bathing and hair trimming, making it easier for owners to keep them clean.  Like dogs, there are also both single- and double-coated cat breeds.         
  8. False.  Even though Rex cats shed little hair and the hairless Sphynx cats shed no hair, they both still have dander, allergen deposits from their saliva, sebaceous gland secretions, and urine on their hair and/or skin, and in their litter boxes.   
  9. True.  According to report published in the December 2000 issue of the Journal of the American Medical Association, cats with dark coats may provoke more allergic reactions than those with lighter-colored coats.  Researchers found the odds for a reaction were six times higher with a dark cat.
  10. True.  Cockatiels, cockatoos, African grays and pigeons (known as “powder down” birds) can produce large quantities of white powdery dust on a daily basis.  The powder becomes airborne every time a bird preens (runs its feathers through its beak), shakes its body or ruffles its feathers.  Misting the bird with water several times a week will keep the powder at a bearable level.
  11. False.  While it’s true that rabbits are very clean animals and make wonderful pets, they can cause as many allergic reactions as cats, because they constantly groom themselves with their tongues and coat their fur with saliva, a major pet allergen.    
  12. False.  The spreading of allergens may be less of a problem with small furry animals that live in cages, but even they can trigger allergic responses.
  13. False.  Allergic individuals can ride horses, especially if someone else does the tacking and the allergic individual mounts the horse outside of the barn. Horses themselves may not be the only source of allergens; sensitive individuals are often are more allergic to mold spores and pollens in barns.    
  14. True.  Taking a pet out of the home does help to reduce the indoor allergen load, but it doesn’t get rid of it entirely.  The best alternative is to learn how to “allergy-proof” your pets and your house.
  15. False.  Isolating a pet to one or two rooms in the home does not contain their allergens, because they can be carried into other rooms on the owner’s shoes and clothing, circulate naturally through the air, or spread via air conditioners, heating ducts and fans throughout the house.     
  16. True.  In most parts of the country, tree and grass pollens from the spring into summer, and ragweed and other weed pollens in the fall, are triggers of hay fever or seasonal allergic rhinitis.  Individuals sensitive to both pets and pollens may find their pet allergy symptoms are worse during pollen season because of double exposure to both types of allergens.  Additionally, pets can carry pollen indoors on their coats, further exposing their owners to additional pollen. 
  17. True.  Allergy sufferers can be sensitive to the animal fur and wool or feathers in clothing, fabrics, sweaters, glove linings, toys, cushions, blankets, and rugs.  Items made of rabbit fur can be particularly irritating because the fur is too delicate to remove all traces of dander and dried saliva.  Feather- and down-stuffed pillows, comforters and duvets also trigger allergic reactions.  The culprits are not the feathers and down, but more commonly, the dust mites that are hiding and growing in them.   
  18. False.  According to an interview published in Allergy & Asthma Health magazine, Robert A. Wood. M.D, Director of the Pediatric Allergy Clinic, Johns Hopkins University School of Medicine said, “There are no convincing studies demonstrating the direct clinical benefits of removing an animal from the home. No research has focused on whether finding a new home for a pet will eliminate the pet-related asthma or allergy symptoms.”  While symptoms may not go away, they can be very manageable.  Most people with pet allergies can live with their pets if they take certain precautions that will minimize allergens on the pets themselves and in their homes.

More on Hypoallergenic Cats & Dogs

There has been a long-believed myth among those who want pets, but who are also allergic to them, that there are several breeds of dogs and cats that are hypoallergenic. Is this true?

The answer is an emphatic no!

There are no breeds of cats or dogs that are hypoallergenic; however, having said that, we would like to qualify the answer. While there are no hypoallergenic breeds, there are some animals that may be reasonably close to being hypoallergenic.

Within any given litter of dogs or cats of any breed, you may, on occasion find an animal that you do not have a reaction to or, conversely, one that you are especially sensitive to.

This condition is not breed specific. It can happen in any breed. It is litter specific. . . and it does not mean that all litters contain an animal that is relatively allergen free nor does it mean that the balance of a litter that contains one relatively allergen free animal is likely to be all relatively allergen free.

However, as a generality, female animals produce fewer allergens than males. Studies show that allergen production is controlled by hormones: males produce more allergens than females. When males are castrated, the quantity of allergens produced decrease within a month.

Unfortunately, if you are looking to buy a kitten or puppy, this doesn't help you very much. All puppies and kittens have soft, supple skins. At this early age, an allergic person can probably handle any one of them and not have much, if any, of a reaction. It is as the skin ages and becomes less supple and the sebaceous glands begin to produce more oils (sebum) that allergy problems begin to appear.

Virtually every article that we have read and every person that we have spoken to about animal allergies talks only about dander. This may be because dander can be easily seen and understood. Dander is important as a problem causing allergen, but it is not the key one. Dander is usually the simplistic explanation of the cause of animal allergies.

Dander may be part of the cause of reactions to cats and dogs, but the real culprit and cause of the major reactions is from the secretion of the sebaceous glands. All skin, human or animal, contains these glands which produce an oily lubricant that keeps the skin supple and the hair shiny. It is from this secretion that Fel d1, the cat allergen, surfaces. (It also surfaces from the saliva of persistent self-cleaning cats). The protein composition of dander can, and does cause reactions, but the majority of the serious reactions to cats stem from the Fel d1 allergen.

Lots of hair, little hair or no hair. All cats produce oils from their sebaceous glands, and this is the major allergen problem. The amount of hair that a cat has or does not have plays little or no significant part in its allergenicity. Cats, by the way, are probably responsible for two-thirds of all pet related allergies.

Because dogs are not self-cleaners to the extent that cats are, dogs tend to have more dander, however, it is still the production of the sebaceous glands that greatly adds to the causal effect of allergic reactions to dogs. Like cats, the amount of hair a dog has or does not have, or whether the hair sheds or does not shed, plays little in its ability to cause allergic reactions. Articles have appeared recommending low-shedding or non-shedding breeds, i.e. Poodles, Maltese, Bedlington Terriers, Kerry Blue Terriers and even the current fad of cross-breed 'designer dogs,' such as Labradoodles, Schnoodles, Yorkiepoos, Cockapoos, Pomapoos, Peke-a-Poms, Golden Doodles and others, as being hypoallergenic. Please note: These cross-breeds are exactly that and are not likely to reproduce themselves again. From the allergy viewpoint, they can be every bit as allergenic as all registered and mixed-breed animals. They are not recognized by the American Kennel Club, the Canadian Kennel Club, the British Kennel Club or the worldwide Federation Cynologique International (F.C.I.)

Another common misconception is that the fur of some breeds is like human hair, and thus these breeds do not cause allergic activity.

These statements are definitely not so.

Every few years there is a claim of a newly developed hypoallergenic cat or dog that can be bought at an exorbitant price with scientific innuendos of hypoallergenicity, but never with any actual scientific data. They receive lots of PR & TV time and sound very good. Be very careful and ask for scientific data if you should be interested in buying one.  

All is not necessarily lost for someone who is set on buying a pet or needs help in keeping one. There are many things that can be done around the house and products to use that will frequently ease the problem. . . there are no guarantees, but the odds are better than 50/50 and certainly worth a try.

The book "Allergic to Pets?" explains in detail how to allergen-proof your home, room by room. If you are sensitive to pet allergens, you are probably allergic to other airborne non-animal sources found in your home, especially dust mites. Reducing or eliminating these from your environment will greatly help to lower your allergic threshold and make living with your pet more comfortable.

Allerpet has a very good brochure with information about pet-related and dust mite allergens . . . how you can minimize them and how to take care of your home.
