No such thing as an allergy-free dog?

I recently wrote an article for my print column about dog breeds that are generally recommended for people with allergies to pet dander. So it was interesting to read in CBC News about this recent study by U.S. researchers that suggests there may be no such thing as a truly hypoallergenic dog.

The researchers analyzed dust samples from 173 homes in which dogs resided to determine how many allergens were present in those homes. Some 60 different dog breeds were involved in the study, 11 of them considered hypoallergenic. The results: There were no significant differences in allergen levels between homes with hypoallergenic dogs and non-hypoallergenic dogs, CBC News reports.

Does this mean there’s no such thing as a hypoallergenic dog? In my opinion, one research study alone doesn’t make it an open-and-shut case. However, the findings do generate more questions about the nature of allergic reactions. I’ve heard from readers in the past who have had allergic reactions to some breeds of hypoallergenic dogs while having no problem with other breeds. The jury’s still out.
