The honest answer, not the marketing version.
Short answer: no dog is truly hypoallergenic, and that includes the Havanese. Longer, more useful answer: the breed's long silky coat sheds very little compared to most dogs, which means less loose hair and dander circulating through your house, and a lot of people who react badly to other dogs do fine around a Havanese. Here is what is actually going on.
Most dog allergies are a reaction to proteins carried in dander, saliva, and urine, not the hair itself. A dog that sheds less spreads less of that dander around the house and onto furniture, which is the main reason low-shedding breeds tend to be better tolerated.
The Havanese has a single silky coat with a soft undercoat and no harsh guard hairs, and it grows continuously rather than shedding out in big seasonal blowouts the way a double-coated breed does. Less loose hair on the floor generally means less dander riding along with it.
Every dog produces some dander and saliva, and individual sensitivity varies a lot from person to person. A Havanese can still trigger a reaction in someone with a strong dog allergy, especially with heavy or prolonged exposure. Nobody can promise a specific puppy will be allergy-friendly for a specific person before you actually spend time together.
The bottom line
If you have mild to moderate dog allergies and love Havanese, it is worth a real test: spend time with an adult Havanese in person, ideally more than once, before committing to a puppy. If you have severe, medically diagnosed dog allergies, talk to your allergist first regardless of breed.
