If you've never had a pet allergy before, you might think you're safe. But it's possible to develop a pet allergy later in life. In fact, about 10% of people who are allergic to pets develop their allergy after the age of 20.

Can You Develop Pet Allergies Later in Life?

What Causes Pet Allergies?

Pet allergies are caused by a reaction to proteins found in pet saliva, urine, and dander (dead skin cells).

These proteins can get into the air and be inhaled, causing an allergic reaction. Symptoms of a pet allergy can include:

  • Sneezing
  • Runny nose
  • Itchy, watery eyes
  • Coughing
  • Wheezing
  • Difficulty breathing
  • Skin rash
  • Hives

Risk Factors for Developing a Pet Allergy Later in Life

There are a few factors that can increase your risk of developing a pet allergy later in life, including:

  • Having a family history of allergies: If you have a parent or sibling who is allergic to pets, you're more likely to develop an allergy yourself.
  • Exposure to pets: The more you're exposed to pets, the greater your risk of developing an allergy.
  • Certain respiratory conditions: People with asthma or other respiratory conditions are more likely to develop pet allergies.
  • Age: As you get older, your immune system may become more sensitive to allergens.

How to Prevent Pet Allergies

There is no surefire way to prevent pet allergies, but there are a few things you can do to reduce your risk, including:

  • Avoid exposure to pets: If you know you're allergic to pets, the best way to prevent an allergic reaction is to avoid contact with them.
  • Wash your hands after petting a pet: If you can't avoid contact with a pet, be sure to wash your hands thoroughly with soap and water afterwards.
  • Keep your home clean: Vacuuming and dusting regularly can help to remove pet dander from your home.
  • Use a HEPA filter in your vacuum cleaner: A HEPA filter can help to remove allergens from the air.
  • Get allergy shots: Allergy shots can help to desensitize you to pet allergens.

Conclusion

If you think you might be allergic to pets, it's important to see a doctor for diagnosis. Early diagnosis and treatment can help to reduce your symptoms and improve your quality of life.
