Keeping or Getting Rid of a Pet

One of the worst discoveries pet owners can make is that they are (or a family member is) allergic to a pet, especially after strong emotional bonds have formed. If someone in the household has developed allergies to a beloved pet, you must make the heart-wrenching decision about whether or not to keep the animal.

Most people have strong a strong bond with their dog, so parting with it can be an agonizing decision.

Before jumping to any decisions, though, first have the allergy confirmed by testing. If the test comes back positive, most allergists will recommend that the pet causing the allergies be removed from the home to avoid the possible progression of symptoms and to decrease the amount of medication the allergic person requires. Once you've received the results and heard the recommendation, you'll have to decide what to do.

Allergen-Free Cats
The
world of genetic manipulation now includes pets. Researchers at a U.S. biotechnology company called Transgenic Pets are devising ways to produce an allergen-free cat. Through genetic engineering, researchers inactivate the gene responsible for creating protein secretions to which humans are allergic. There's no word yet about when genetically modified felines will make their debut -- at $700-$3000 a cat. Critics question the ethics and long-term health effects of tweaking a cat's genetic makeup just to suit allergy sufferers.

The Decision: Stay

While allergists are generally correct when they recommend removing a pet, doing so is like losing a family member. Some people, understandably so, are unwilling to give up their pet. Instead, they choose to live with the pet by modifying behaviors and keeping the house as dander-free as possible. If this is the route you decide to take, consider the following suggestions:
  • Wash and brush dogs and cats once a week. Have a nonallergic family member brush the pet outside daily.
  • Make the allergic family member's bedroom and bed strictly off-limits to those with four paws. But be aware that, even though the pet's territory is contained, allergens won't be. Allergens spread far and wide with help from the heating and air-conditioning system, and they get a ride on people's clothing. High efficiency air filters should be used in the bedroom's heating and air-conditioning systems, if the residence has a forced-air system, and they should be maintained every two to three months to help reduce dander distribution.
  • Make it a petty crime for pets to jump on furniture, but do provide them with a nice bed to call their own. If the pet's bed is washable, wash it weekly using hot water. Remember: Dust mites don't discriminate when it comes to dander.
  • Consider keeping pets outside. This may be a good option for the allergy sufferer; however, in most cases this is a poor option for your pet, who will probably be happier and healthier in another family's home. Use your best judgment when deciding a pet's fate. Does it like to be outside? Does it have adequate room to run and play? Is the environment too cold in the winter or too hot in the summer? Does it have protection from the elements? Is it accustomed to constant attention from the family? Does it annoy the neighbors by barking?
  • Do not let allergic family members hug, kiss, or cuddle pets. If the momentary lapse of love happens, make sure hands get washed after contact.
  • If possible, use a central air cleaner for at least four hours a day. These air cleaners can help to remove significant amounts of pet allergens from the home.
  • Vacuum carpets daily. Damp dust furniture twice weekly. Maintain all your regular allergy-proofing tasks.
  • Place the litter box in an isolated area, where it won't be affected by the home's circulation system. You don't want to circulate the allergens and odor from the litter all over the house. Allergic persons should not clean the litter box. If they must, make sure they wear a mask and gloves.
Farewell to Fido

If you decide to take this prescribed route, don't expect instant relief from allergy and asthma symptoms. It takes an average of 20 weeks, plus daily heavy-duty vacuuming, dusting, and washing, as well as carpet cleaning, to reduce the levels of allergens to those found in pet-free homes. While people with mild to moderate pet allergies may sometimes be able to keep their pets by following the above recommendations, those with severe pet allergies and/or asthma or who suffer life-threatening reactions may need to give them up. Saying good-bye to a beloved pet is never easy, especially for children. But there are ways to make the ordeal a little easier. Try these suggestions for easing the emotional trauma of giving away a pet:

Think it out together: Start with a family brainstorming session in which each family member presents their own ideas and options for giving away the pet. When children help find a good home for their companion, they are better able to deal with the loss.

Help for the
Nonallergic Child
Often a nonallergic child resents the fact that a sniffling sibling puts the kibosh on having a pet. One way to heal hurt feelings is to have the nonallergic child volunteer (if old enough) at a local animal shelter. Make sure they have a separate outfit for their volunteer work (and that they change in and out of it before they get in the car!) since pet dander is easily transported on fabric.

Hear ye, hear ye: Spread the word to family, friends, and coworkers about the need to relocate your pet. Just be sure they are aware of the medical reason so that potential adopters will not think you are trying to pass off a carpet-chewing, ill-tempered problem pet. If you're not successful with personal contacts, advertise your pet in the newspaper's pet section. Again, be sure to mention in the ad that you're giving the pet away for medical reasons, and screen people as best you can to find a good home. The grocery store community bulletin board is another good place to advertise. Put up signs with pictures of your pet and descriptions of its personality.

Creative advertising: If newspaper and grocery store advertising fails to produce a satisfactory home, it is time to get creative. Try taking your dog to a popular park, carrying a sign describing your plight. Or go door to door with a picture of your cat -- or approach a pet-store owner about selling your bird.

Give them shelter: Sending a pet to a shelter is a last-ditch option, when all else has failed and your family's health is threatened. Shelter living is very traumatic for a pet accustomed to a household, and older pets probably will not get adopted. There are some very good no-kill animal shelters that are an alternative to city animal shelters, but their resources are limited financially and your pet will do much better in a family environment.

Handling the Demand for a Pet

Even when there's an allergic person in the household, there will be family members (especially children) who believe the world will end if they don't have a pet. Persistent begging can be such a source of irritation to parents that they relent. If a pet is necessary to prevent parental insanity (or for other reasons), remember that pet allergens are the proteins found in dander, as well as the saliva and urine of cats and dogs. Find a pet without fur or one that doesn't produce allergy-causing excretions. Let it be known that the cute and cuddly don't fit into this category.


Tropical fish make the ideal pet for allergy sufferers, as long as the aquarium does not add to the humidity in a room and mold doesn't grow around the rim. Picking out beautiful tropical fish can be a fun family activity and one that may help kids get over not having a four-legged fluff ball. For adults, a koi pond may be a good investment because everyone loves watching these brilliantly colored fish. Some koi are tame enough to be petted, too. Hermit crabs make for an unusual pet, and they are generally low maintenance. Snakes, turtles, salamanders, and lizards are also possibilities, but some of these pets require a lot of maintenance. Many need humid environments, which can set off mold and dust-mite allergies. And some may not be appropriate due to other health or nonhealth concerns. Thoroughly investigate these choices before selecting a pet, and make sure the allergic person does not have any reactions.

Dealing with pet allergies can be a strain on the family. First you need to know the extent of the family member's allergy. Then it may be time to make a hard decision. Whatever you decide, you can follow these suggestions for minimizing the disruption to your life.
