This is an article that my mother wrote. I think it very helpful as the terms can be SO confusing!
F1 MINI DOODLE >>>In the case of a mini Goldendoodle, this consists of a Purebred Female Golden Retriever bred to a Purebred Mini male Poodle. >>>There are a few ways to get a mini Aussiedoodle. You can cross a miniature poodle with a miniature Australian Shepherd, you can artificially inseminate a standard female Australian Shepherd with a miniature male Poodle, or you can use a standard female poodle and artificially inseminate it using a miniature make Australian Shepherd. This first generation (F1) is considered the purest of the breed cross, being exactly half Golden Retriever or Australian Shepherd and Poodle. As first generation matings, these dogs have the added health benefits associated to Hybrid Vigor. This is a phenomenon in animal breeding referring to the fact that the first cross between two unrelated purebred lines is healthier and grows better than either parent line. They are expected to weigh between 20-40 lbs at maturity. Coat Maintenance: Moderate to high care Coat Description: Coat grows to a natural body length of 3-5 inches which requires combing and occasional grooming. Many choose to have the fur cut back once every few months to keep the fur shorter and easier to maintain. Coats are usually wavy or curly, with a rare shorter hair coat. Shedding: Very little to none. Allergy Friendliness: Usually successful in families with mild to moderate allergies.
F1 STANDARD DOODLE The F1 standard is much like the F1 mini. The only difference is the size. An F1 standard doodle can be expected to weigh anywhere from 45-65+lbs.
F1B Is a first generation Goldendoodle or Aussiedoodle bred back to a poodle. At this point, the dogs are 75% poodle and 25% retriever or Aussie. Even though they are a higher percentage of poodle, they generally exhibit the same wonderful temperament as an F1 cross. Being 75% poodle, they are one of the most hypoallergenic of the doodle crosses and also shed the little to none. Coats are usually wavy or curly and shedding is light to non-shed. Coat Maintenance: Moderate to high care Allergy Friendliness: Usually successful in families with mild to severe allergies.
F1BB This generation is created by crossing an F1b Goldendoodle or Aussiedoodle back to a poodle. They are known for their consistency, most having curly coats that shed very little to none. Being the most allergy friendly of any doodle generation, they are normally successful in families with high allergy concerns. At this point, the mix is 87.5% Poodle and 12.5% Golden Retriever or Aussie. Coat Maintenance: Moderate to high care Coat Description: Coat grows to a natural body length of 3-5 inches which requires combing and occasional grooming. Many choose to have the fur cut back once every few months to keep the fur shorter and easier to maintain.
F2 These are the most unpredictable, as at this point you are breeding two doodles, which waters down the health and vigor tremendously, as well as the coat predictability. You can't be sure which parent lines will come out and you can end up with some resembling the retriever parent more so than a doodle. They also lose their allergy friendly status at this level as well. Coat Maintenance: Moderate to high care, can also be low if the dog is retriever like. Allergy friendliness: Not recommended for families with allergies.
MULTIGENERATIONAL The third generation doodle (F3) is produced by crossing the F1B or F2 with another F1B or F2 doodle. When breeding F3 doodles, a high number of puppies in the litter will be more prone to shedding. Some are very retriever'ish or Aussie-like with flat, sporty coats, not the soft, fluffy coats our doodles are known for. When choosing a pet for their low shed and hypo allergenic qualities, the lighter fluffier coats are what you should aim for. Coat qualities vary from retriever like to doodle like. Coat Maintenance: Moderate to high care, can also be low if the dog is retriever like. Allergy friendliness: Not recommended for families with allergies.
All puppies will shed their "puppy coats" for about the first year of their lives. After their adult coats come in, they should shed very little to none.
