One of the most common reasons why people buy Goldendoodle puppies is because of their hypo-allergenic fur. So, what makes fur hypo-allergenic? Is it the fact that the fur is not shed at all?
Contrary to popular belief, all dogs shed. And why is that so surprising? People, cats, mice, even birds shed! However, dog breeds that shed less are more likely to be hypoallergenic.
Why is this the case?
Well, the protein expressed in a dog's saliva can cause an allergic reaction in some individuals. Since the dog's dander and saliva stick to their hair, and breeds less prone to shedding do not release as much hair into the environment, "hypoallergenic breeds" typically shed less.
However, protein expression levels play a major role and amount of shedding alone does not determine degree of allergic reaction. Dr. Wanda Phipatanakul, Chair of the Indoor Allergen Committee of the American Academy of Allergy, Asthma, and Immunology is quoted in U.S. News & World Report as saying, "Even if you get a hairless dog, it's still going to produce the allergen."
Are Goldendoodles hypoallergenic?
Most allergen experts would not answer this question outright. They would probably say that the purchasing a Goldendoodle would have a higher probability of not causing an allergic reaction than a higher shedding breed.
Now, the reason behind the reduced shedding is all in the breeding. Poodles, a breed known for their "non-shedding" fur (which we now know is an anomaly) is crossed with a golden retriever (which is a highly shedding breed). The resulting F1 Goldendoodle (50% poodle & 50% golden retriever) sheds much less than a retriever, however it is likely to shed more than a poodle.
When an F1 Goldendoodle (50% retriever / 50% poodle) is cross bred back to a poodle the resulting F1B Goldendoodle (25% retriever / 75% poodle) sheds even less. Some even say their F1B Goldendoodle never sheds (again an anomaly).
