There are several reasons why small dogs are hypoallergenic. Since they are small, many breeds cannot climb on the couch, bed, or other furniture. With fewer allergens on the furniture, you will not be as affected by them. Small dogs want to have their own space. They will sleep in a dog bed or blanket that you should wash often. Keeping small dogs in a crate during the day while you are gone will make them feel safer and also prevent them from destroying your home. This will also reduce allergens from getting into the carpets and on the walls.

Small dogs usually have shorter hair or they have hair that is long and thin. This hair does not seem to cause as many problems to those with dog allergies. Their hair is easy to take care of and does not shed as often as other breeds. While you will have to take these dogs to be groomed more often, you should be able to breathe easily around them. Since the dogs do not shed as often, less dander is present in carpeting and on walls as well.
Most small dog breeds do not produce a lot of saliva. Saliva can also cause people to have allergy attacks. This is because of bacteria that are found in the saliva.
