The shed and allergy factor of a Goldendoodle can be different from Breeder to Breeder depending on the Coat Type their Goldendoodles have inherited. At Hilltop Pups we DNA test the coat type of all our dogs so we can create the most non-shedding hypoallergenic coat as possible. When breeding a Goldendoodle to a Goldendoodle the parent dogs need to be DNA tested for "IC" Improper Coat, which determines the dogs shed factor. If one of the Goldendoodles in the pairing is F/F gene carrier for Furnishing and the other is F/F or F/IC a carrier for IC then none of the puppies will shed. I have three males that are IC clear with F/F here. I follow this DNA rule when breeding to make sure my dogs are non-shedding. No guess work involved here past the first generation; as first generation is the crossing between the Golden Retriever and Poodle the coat types will vary widely in the litter;) You can brush them and not even get hair to pull out.
