Allergies or sensitivities to pets with fur or feathers are common, especially among people who suffer from other allergies or asthma. It is estimated that 15 to 30 percent of all people with allergies have allergic reactions to cats, dogs, dust mites and pet dander. 

Dog allergies may include all dogs or to only a few specific breeds.

Cat allergies are about twice as common as dog allergies. Cat and dog allergens are everywhere in the home, especially in carpets and bedding. Pet dander may even be present in homes that have never been occupied by these animals, because it is carried on people’s clothing. The allergens get in the air with petting, grooming or stirring the air where the allergens have settled. Once airborne, the particles can stay suspended for long periods of time.

If you must have carpet, select ones with a low pile and steam clean them frequently. Better yet, use throw rugs that can be washed in hot water.

Wear a dust mask to vacuum. Vacuum cleaners stir up allergens that have settled on carpet and make allergies worse. It is best to use a vacuum with a HEPA (high efficiency particulate air) filter if possible.
