What is pet dander allergy?
'Dander' refers to microscopic flakes of skin shed by animals, which carry allergenic proteins along with proteins from saliva and urine. These particles are extremely lightweight, stay airborne for long periods, and settle into carpets, upholstery and bedding — meaning exposure continues even when the pet isn't in the room.
Conditions it commonly triggers
Pet allergens can trigger or worsen allergic rhinitis, asthma, and allergic conjunctivitis in sensitised children, and contact with a pet can occasionally cause skin symptoms too.
A note on cat vs dog allergy
Cat allergen tends to be smaller and stickier, spreading further through a home and even to places the cat has never been (like via clothing at school). Dog allergen varies more by breed, though no dog breed is truly '100% non-allergenic.'
Reducing exposure at home
- Keep pets out of the child's bedroom, especially off the bed
- Use a HEPA air purifier in main living areas if a pet stays indoors
- Bathe pets regularly if advised, and groom them outdoors where possible
- Vacuum upholstery and carpets frequently with a HEPA-filter vacuum
- Wash hands after handling a pet, especially before eating
Testing & treatment
Skin prick testing confirms whether a child is truly sensitised to a specific pet before recommending the difficult step of rehoming — this decision should always be guided by objective testing and a full clinical picture, not assumption.
Talk to Dr. Narwani: If your child's symptoms are affecting sleep, school, play or growth, or you suspect a specific trigger, book a consultation for proper allergy work-up rather than guessing at home remedies.
