A hypoallergenic dog is a dog that is more suitable for people with allergies. Hypoallergenic dogs can still cause allergies but in a milder manner. In some people with allergies, specific hypoallergenic breeds do not trigger any allergy symptoms. The significant allergen for most people is a protein found in the dog's saliva and dander.

Here is a list of all of the known hypoallergenic dogs:
