Inspired by one of our favorite television shows, Allergy Myth Busters looks at a number of popularly held beliefs about allergy. But are these myths just urban legends or are they true?
Myth: Some breeds of dogs are hypoallergenic, so dog allergic patients can tolerate having these dogs in the home.
Busted!For many of us dog allergies interfere with our love for these furry companions. Exposure to the allergens from our beloved pets can lead to nasal, eye, skin and breathing symptoms which can make life miserable. That makes the innovation of the “hypoallergenic” dog an amazing breakthrough! Unfortunately what is well known to allergists is that the existence of a hypoallergenic dog is a MYTH.
In a study published in 2012, investigators from the Utrecht University in the Netherlands compared Can f 1 levels (the major dog allergen) in the pet hair/coat samples and the home environment of various alleged hypoallergenic (Labradoodle, poodle, Spanish Waterdog, and Airedale terrier) and non-hypoallergenic dogs (Labrador retriever and a control group composed of 47 different non-hypoallergenic dog breeds and several crossbreeds.)They found that that Can f 1 levels in hair and coat samples were related to the breed, BUT there was a high variability within individual breeds. Can f 1 levels were significantly higher in hair and coat samples in dog breeds considered hypoallergenic thus they are not less allergenic than any other dogs. Similar findings were published in another study from 2011 which examined dog allergen levels in homes of hypoallergenic versus non-hypoallergenic dogs. It, too, showed that there was no evidence of decreased shedding of allergens by dogs grouped as hypoallergenic.
The myth of the hypoallergenic dog has been debunked. For those people who do suffer from dog allergy, this does not mean that they have to get rid of their pet. Those people who don’t want to give up “man’s best friends” can always try allergy medications or be evaluated for immunotherapy/ allergy shots. If you suffer from allergies to your pets, Allergy Partners can help you find relief.
