One of the most common allergens in the world is pet hair. Some of us might have dog hair allergies, and getting a dog can be problematic. Luckily, one of the amazing characteristics dogs can have is - they are hypoallergenic. What makes a hypoallergenic dog so great is they do not produce so many allergens. That usually means they do not shed, or they don’t have hair.
Keep in mind that there are no true hypoallergenic dogs. All dogs produce at least some sort of allergens. We can be allergic to the enzymes in their saliva or dandruff. However, there is something all hypoallergenic breeds share - they seem to cause fewer allergic reactions. Even the owners that have severe allergic reactions seem to bear these breeds.
