Are You Allergic To Your Pet?
Allergens from cats and dogs are found in skin cells the animals shed (dander), as well as in their saliva, urine and sweat and on their fur. Dander is a particular problem because it is very small and can remain airborne for long periods of time with the slightest bit of air circulation. It also collects easily in upholstered furniture and sticks to your clothes. Pet saliva can stick to carpets, bedding, furniture and clothing. Dried saliva can become airborne. So-called hypoallergenic cats and dogs may shed less fur than shedding types, but no breed is truly hypoallergenic.
Rodent pets include mice, gerbils, hamsters and guinea pigs. Allergens from rodents are usually present in hair, dander, saliva and urine. Dust from litter or sawdust in the bottom of cages may contribute to airborne allergens from rodents. Rabbit allergens are present in dander, hair and saliva. Pet allergy is rarely caused by animals that don’t have fur, such as fish and reptiles.
Pet allergies are common. However, you’re more likely to develop a pet allergy if allergies or asthma runs in your family. Being exposed to pets at an early age may help you avoid pet allergies. Some studies have found that children who live with a dog in the first year of life may have better resistance to upper respiratory infections during childhood than kids who don’t have a dog at that age.
Pet allergy signs and symptoms caused by inflammation of nasal passages include:
- Runny nose
- Itchy, red or watery eyes
- Nasal congestion
- Itchy nose, roof of mouth or throat
- Postnasal drip
- Facial pressure and pain
- Frequent awakening
- Swollen, blue-colored skin under your eyes
- In a child, frequent upward rubbing of the nose
If your pet allergy contributes to asthma, you may also experience:
- Difficulty breathing
- Chest tightness or pain
- Audible whistling or wheezing sound when exhaling
- Trouble sleeping caused by shortness of breath, coughing or wheezing
Some people with pet allergy may also experience skin symptoms, a pattern known as allergic dermatitis. This type of dermatitis is an immune system reaction that causes skin inflammation. Direct contact with an allergy-causing pet may trigger allergic dermatitis, causing signs and symptoms, such as:
- Raised, red patches of skin (hives)
- Itchy skin
If you have a pet allergy, the best strategy is to avoid or reduce exposure to the animal as much as possible. Medications or other treatments may be necessary to relieve symptoms and manage asthma. Some signs and symptoms of pet allergy, such as a runny nose or sneezing, are similar to those of the common cold. Sometimes it’s difficult to know whether you have a cold or an allergy. If symptoms persist for more than two weeks, you might have an allergy.
