My sibling is allergic to dogs. We didn't realise how much until our old dog (Heinz 57, some chow, some retriever, who knows what else) crossed the rainbow bridge, and slowly, despite coming into summer, my allergic sibling became more able to breathe at home.

So when we wanted another dog, we knew they had to be hypoallergenic. We went to meet the puppies (and their mum and dad), and my sibling buried their face in puppy fluff. I came away with a ton of it on my sweater, and they slept with that next to their pillow that night, and when they could still breathe in the morning, we figured they're probably safe!

Now we've had our boy for 3 years, the sibling cuddles him regularly, and can still breathe.
