Hypoallergenic Dogs A Myth?
It turns out that the so-called "allergy-free dogs" are not so allergy-free.According to a study by a team of researchers at Henry Ford Hospital in Detroit found that alleged hypoallergenic dogs, such as Poodles, Portuguese Water Dogs, and Labrador Retriever-Poodle mixes, do not have lower allergen levels in their homes.
People with pet allergies suffer bouts of congestion, coughing, sneezing, and red, itchy eyes. The harmless proteins, found in a dog's saliva and sebaceous, or skin, glands cause the adverse reactions. The proteins are then deposited on the coat through self grooming, or flakes of dead skin (dander) fall off the body, sticking to just about anything.....walls, carpets, and clothing.
For this study, Henry Ford researchers analyzed dust samples, collected from the carpet or floor of 173 homes, for the dog allergen Can f 1. In all, 60 dog breeds - 11 of which were widely considered hypoallergenic - were involved in the study.
Researchers found no significant differences in allergen levels between home3s with a "hypoallergenic" dog and those with other dogs.
The findings are published online in the July/August issue of the American Journal of Rhinology & Allergy.
