A new study to be published online in The American Journal of Rhinology and Allergy reveals that the amount of dog allergens found in households with dogs does not vary depending on the breed.
In other words, families with so called 'hypoallergenic' dogs are living with the same level of allergens in their homes as people who own non-hypoallergenic canines.
According to The New York Times, Dr. Christine Cole Johnson, an epidemiologist at Henry Ford Hospital in Detroit and senior author of the study, had this to say about low-allergy or allergy-free dogs:
"I have no idea where this whole concept came from. It's been around a long time, and maybe people associated it with shedding. I think it's just a legend."
Study researchers measured the level of the most common dog allergen, Canis familiaris 1, or Can f 1, found in the homes of 173 families that owned one dog. Out of the 173 samples, only 10 had less than measurable amounts of Can f 1. No matter what type of dog was in the home, there was no significant difference in the level of allergens measured.
