Breed advice for allergy sufferers

My family and I are desperate for a dog. I’ve always lived with dogs, and my two boys (11 and 6) would love a dog. We live in a perfect place for a dog - we have a large, secure garden, surrounded by woodland.

My husband also wants a dog - but he is allergic to many things. Cats really set him off and some dogs, so we want to make sure we get the right dog for him. How can we find a hypoallergenic breed? Someone mentioned to me that there’s no such thing! How can we reduce his chances of reacting?
