Many people assume they're allergic to pet hair, but the real culprit is usually proteins found in a pet's dander (dead skin cells), saliva, and urine. Cats and dogs are the most common sources of pet allergies, although birds, rabbits, guinea pigs, and other furry animals can also trigger allergic reactions.
If you notice symptoms that consistently occur around your pet or improve when you're away from home, pet allergies may be the cause.
Common Symptoms of Pet Allergies
Pet allergy symptoms often resemble seasonal allergies and may include:
- Frequent sneezing
- Runny or stuffy nose
- Itchy nose or throat
- Red, watery, or itchy eyes
- Postnasal drip
- Persistent cough
- Wheezing or shortness of breath
- Chest tightness, particularly in people with asthma
- Itchy skin
- Hives or a rash after touching your pet
- Ear itching or congestion
- Reduced sense of smell or taste
- Fatigue caused by ongoing allergy symptoms
- Dark circles under the eyes, sometimes called "allergic shiners"
Can Pet Allergies Trigger Asthma?
Yes. Pet allergens are a common asthma trigger and can worsen existing asthma symptoms. Exposure may lead to increased coughing, wheezing, chest tightness, or difficulty breathing. If you have asthma and notice your symptoms worsen around pets, it's important to discuss this with an allergist.
How Can You Tell if You're Allergic to Your Pet?
One of the strongest clues is when your symptoms occur. Pet allergies often:
- Worsen after petting or playing with your pet
- Flare up in rooms where your pet spends the most time
- Improve when you're away from home or in pet-free environments
- Return shortly after you're back around your pet
Keep in mind that pet allergens can remain on furniture, carpeting, bedding, clothing, and other surfaces for months. You may continue to experience symptoms even when your pet isn't in the same room.
How Are Pet Allergies Diagnosed?
An allergist can determine whether you're allergic to your pet by reviewing your medical history and performing allergy testing. Diagnosis may include:
- Skin prick testing
- Blood testing for pet-specific allergies
Because pet allergy symptoms can overlap with seasonal allergies, dust mite allergies, mold allergies, chronic sinus conditions, and asthma, proper testing helps identify the true cause of your symptoms.
Do You Have to Give Up Your Pet?
Not necessarily. Many people are able to keep their pets while successfully managing their allergies. Your treatment plan may include:
- Allergy medications to relieve symptoms
- Reducing pet allergen exposure throughout your home
- Using HEPA air filtration and frequent cleaning
- Keeping pets out of bedrooms or other designated areas
- Allergy immunotherapy (allergy shots) to reduce sensitivity over time
Your allergist can recommend the treatment approach that's right for your symptoms, lifestyle, and overall health.
When Should You See an Allergist?
If you have persistent allergy symptoms that seem to worsen around your pet, don't ignore them. An allergy evaluation can determine whether your pet is the cause and help you develop an effective treatment plan. With the right diagnosis and management strategy, many people are able to control their symptoms while continuing to enjoy life with their pets.
