Generations explained:
F1 refers to first generation and is the result of a purebred bred to a purebred of a different breed. For example, a golden retriever to a poodle.
An F1b puppy is when one purebred parent (like a poodle) is bred to an F1 (a 50% poodle x 50% golden). F1b puppies have curlier coats than F1 puppies and are more hypoallergenic.
What is the difference between Aussie, Berne and Goldendoodles?
Aussies (Australian Shepherd) are described by the Australian Shepherd Association as, "An intelligent, medium-sized dog of strong herding and guardian instincts. They are also delightful and loyal companions and great family dogs. They love to be part of the daily hustle and bustle, and enjoy riding in the vehicle just to be with their beloved master."
Berners (Bernese Mountain Dog) are described as by AKC as "Good-natured, calm, and strong. Berners get along with the entire family and are particularly gentle with children, but they will often become more attached to one lucky human. Berners are imposing but not threatening, and they maintain an aloof dignity with strangers."
It should be noted that when bred to a multicolored poodle, the Aussiedoodles and Bernedoodles may be more colorful.
Goldens (Golden Retriever) are described by the AKC as, "Goldens are outgoing, trustworthy, and eager-to-please family dogs, and relatively easy to train. They take a joyous and playful approach to life and maintain this puppyish behavior into adulthood. These energetic, powerful gundogs enjoy outdoor play. For a breed built to retrieve waterfowl for hours on end, swimming and fetching are natural pastimes.
