Did you know that…
Dog dander, not hair, causes the allergy. (https://www.aafa.org/pet-dog-cat-allergies/ )
More people are aware of cat allergies because they are more common, but dog allergies tend to be more severe. “The diagnosis and treatment of patients with allergies to dogs continues to be a challenge in contrast to cats… Studies on the diagnosis and treatment of dog allergies remain inconsistent and difficult to generalize even though dog allergies are a pervasive problem.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5809771/
Dog allergies can be so severe that they are life threatening.
Social awareness is essential, because it is very difficult to treat medically : “...there is a critical need to accurately diagnose and treat patients to reduce morbidity and mortality from exposure.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5809771/
There is no such thing as a truly hypoallergenic dog. (https://www.aafa.org/pet-dog-cat-allergies/) “All dog breeds produce allergenic proteins (even poodles and "hairless" dogs).” (https://pubmed.ncbi.nlm.nih.gov/31690370/ )
A traditional treatment for allergies, Immunotherapy (otherwise known as allergy shots), can work for other allergies but it is less effective for those allergic to dog dander. Thus, it is very difficult to treat dog allergies medically. “The diagnosis and treatment of patients with allergies to dogs continues to be a challenge in contrast to cats” (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5809771/). One of the reasons for this is that dogs output a variety of different allergy inducing proteins (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5809771/ ).
Who is allergic?
5% of Canadians are allergic to dogs - that’s over 1.8 million people.
Allergic people include small children, the elderly, people with disabilities, people facing racial and cultural discrimination and people suffering from mental damage inflicted by having a disease that carries stigma.
How does it work?
Even though dog hair does not cause the allergy, it does operate as a medium for dander to cling to. Saliva and urine also contain proteins that cause the allergy.
The allergens are sticky. Dog dander doesn’t just stick to clothes and carpets - it even sticks to walls. (https://www.aafa.org/pet-dog-cat-allergies/)
Dander accumulates - it does not dissipate with time. Studies find significant amounts of it in houses without any dogs (“Concentrations of dog and cat allergens were elevated in almost all houses with pets but were also high in a significant proportion of the houses without pets.” https://pubmed.ncbi.nlm.nih.gov/7560654/ )
It is not just an issue in a home, but is prevalent in public spaces. The allergens “spread effectively and they are encountered widely in public places.” (https://www.tandfonline.com/doi/full/10.1080/21645515.2017.1409315 )
Every time a dog passes through a public space, more dander builds up and creates a more severe reaction for people who need to use the space. Dander can cause symptoms months after the animal has been in the space. (https://www.aafa.org/pet-dog-cat-allergies/)
What are the physical effects?
The physical effects are primarily caused by dander proteins that get into the eyes, nose and lungs of humans, causing:
