Hypoallergenic means relatively unlikely to trigger allergies or cause an allergic reaction. With the advancement of the genetic testing, we are able produce puppies that are the most non -shedding, hypoallergenic, most allergy friendly possible.
In the past it was believed that you had to get a curly coated Goldendoodle puppy in order for a dog to be hypoallergenic or non-shedding. This is no longer the case. We now know that curl has nothing to do with shedding. Think about other straight-haired breeds, like the Shih Tzus, Lhasa Apso, Bichon etc. They are non-shedding but yet they have NO curl to their coats. In order for a Goldendoodle breeder to produce minimal to non-shedding, hypoallergenic Goldendoodle puppies, the breeder needs to genetically DNA test their parent dogs for the furnishings, improper coat IC genes as well as the shed gene. With the advancement of available DNA genetic testing, we are able to know if the parents carry for IC improper coat furnishings as well as their shed score, both of which influence shedding. However, the overall degree of shedding is dependent on the combination of the dogs genotypes at the SD and IC loci as well as the actual coat traits of the parents. By carefully chosen breeding pairs, it allows us to produce wavy or curlier puppies with minimal to non-shedding, hypoallergenic teddy bear coats. They are relatively unlikely to trigger allergies or cause an allergic reaction.
Be sure your breeder is doing genetic testing on the parents dogs so that they don't unintentionally produce puppies with incorrect shedding coats without furnishings.
**Please note that even if a dog is non-shedding, some folks are allergic to the protein in their saliva or dander. So if in doubt, always check with your allergist first before purchasing a puppy for you and your family.
