Short answer. Pet allergy is usually a reaction to proteins found in an animal's saliva, skin flakes and urine, not to the fur itself. When a pet licks its coat, the saliva dries and flakes off into the air. Short-haired and so-called hypoallergenic breeds still make these proteins, so no breed is truly allergen-free.
If the pet does not shed, why are there still symptoms?
Fur mostly carries the trigger; it is not the trigger. The proteins people react to are made in the animal's saliva and skin. Every pet licks its coat, and every pet sheds skin flakes.
That is why shaving or trimming a pet rarely settles sneezing or wheezing. The source is still there.
How do the proteins reach your nose and lungs?
Dried saliva and skin flakes behave like fine flour. They are light enough to float in room air, and they settle on pillows, sofas, carpets and clothes.
A bedroom the pet sleeps in can hold these flakes all night, which is one reason symptoms may be worse at midnight or on waking.
Does an allergy turn into an autoimmune disease?
Allergies do not directly become an autoimmune disease.
Emerging evidence suggests that severe barrier dysfunction and immune dysregulation may be associated with an increased risk of some autoimmune conditions. That is a reason to take long-lasting symptoms seriously, not a reason for fear.
What helps without giving up the pet?
Start with one clean room. Keep the pet out of the bedroom every night. Wash bedding once a week in hot water. Wash your hands after cuddling the pet, before touching your face.
Hard floors are easier to keep clear than carpets and heavy curtains. Vacuuming at least once a week helps reduce what has settled.

Is any dog or cat breed truly hypoallergenic?
No breed has been shown to be free of the proteins that trigger pet allergy. Individual animals vary, and some people react less to one animal than another, but a label on a breed is not a promise.
When should I talk to a doctor?
If sneezing, itchy eyes, night cough or wheeze has lasted more than four weeks, or clearly follows contact with the pet, it is reasonable to talk to your doctor and mention what you noticed at home.
