Speaking, there’s no such thing as a completely hypoallergenic dog. So if you’re looking for such a dog then you’ll never find one because all canine breeds have hairs. And since dogs have hairs they’ll shed the coat either frequently or seldom.
So if you’re allergic to dogs that shed heavily, your best bet is to go for a breed that’s hypoallergenic or sheds minimally. You can take your pick from Basenji, Brussels Griffon, Lhasa Apso, Scottish Terrier, and Cairn Terrier.

Some dog breeds that shed less hair compared to others have been around for centuries
