I wouldnt be so conclusive. I'm open to the idea that hypoallergenic branding is garbage, but non-shedding certainly is a phenotype, which can have an impact independent of allergens in hair samples.
It is also worth nothing that the cited study showed 4-5 orders of magnitude difference between allergen samples from different animals (0.1 to 1000 ug/g). The results just didn't group well across breeds. IF someone showed me this data at work, I would say they are either failing to isolate causes of variability or have a shitty measurement system.
I would bet to differ here. I've got pretty strong allergies to dogs, i couldn't even stay a night at a girlfriends house without medicating myself to sleep, waking up with a crusty throat, red eyes, and a blocked nose for days straight. But i grew up with a dog who would only ever give my nose a slight itch if i rubbed my face on him for a bit.
The difference? Breed. She had an Australian shepherd (i think), large and shredded a ton absolutely all the time. There were drifts of hair on every corner in the house if she didn't vacuum for a week. We had a havanese poodle mix, small guy, barely shed at all. So sure, if you take the absolute most extreme position possible that hypo means completely no allergens whatsoever at all, then it doesn't exist. But in reality i can live with one dog and can't with another, that's the only definition of hypoallergenic that actually matters to people
There's no such thing - certain breeds being "hypoallergenic" is a straight up lie that was made up by breeders to sell dogs.
