Allergy to dogs is unfortunately common. Many people with dog allergy or a family member with dog allergy who choose to own a dog try to select a dog breed marketed as a low allergy or hypoallergenic breed. Breeds often purported to be low allergy breeds include Poodles, Poodle crosses such as Labradoodles and Groodles, and Airedale terriers. Many owners note substantial variability in their allergic reactivity to different dogs, but is this variation really breed dependent?
Vredegoor, Willemse et al designed a study to try and answer these questions. Their results were published in JACI in October 2012. They looked at levels of the major dog allergen Can f 1 in the hair of dogs and their homes. The measured the levels from a variety of species marketed as hypoallergenic (for example poodles) and from other dog breeds (for example labrador retrievers).
They found no significant differences in levels of Can f 1 dog allergen in the hair and coats of so-called hypoallergenic dogs versus other dog breeds. Interestingly there was substantial variation in dog allergen levels between individual dogs both within and across breeds.
So sadly there appears to be no actual hypoallergenic dog breed. But some dogs may be less allergenic than others - the reasons for this are not absolutely clear as yet.
