Pet Dander Allergy

Symptoms

How It's Diagnosed

• Skin prick test to cat (Fel d 1) and dog (Can f 1) allergens
• Specific IgE blood tests
• Component testing: Fel d 1 (major cat allergen) and Can f 1, Can f 5 (dog)

Avoidance Strategies

• The most effective measure is removing the pet from the home — though not always realistic
• If keeping a pet: ban it from the bedroom and upholstered furniture
• Use HEPA air purifiers in main living areas and bedroom
• Wash hands after touching the animal; avoid touching face
• Hard floors rather than carpet reduce allergen accumulation
• Dander lingers for months after a pet is removed — full decontamination takes time

Is there a hypoallergenic cat or dog?

No breed is truly hypoallergenic. Some breeds produce less Fel d 1 or shed less dander, but all cats and dogs produce allergenic proteins. 'Hypoallergenic' breeds may cause fewer symptoms in mildly sensitised individuals — but not in those with significant allergy.

Before acquiring a pet, spend time with the specific animal to gauge your reaction. Consider allergen testing first.

Immunotherapy for pet allergy

Subcutaneous allergen immunotherapy (SCIT) is an effective option for patients who cannot avoid cats or dogs, or who prefer a disease-modifying treatment. Treatment runs for 3–5 years and can achieve lasting benefit after completion.
