F1: The “F” stands for “filial generation”. “F1” means “first generation” and is a common scientific term. This, in the Labradoodle breed, is the coding for first-cross, purebred Poodle to purebred Labrador Retriever. The results are mixed, as this is not the breeding of two “like” dogs, or dogs that resemble each other. F1 Labradoodles typically are moderate- to low- shedding and have a sparse-hair to fleece coat.
F1B: The additional “B” refers to backcross — an F1 Labradoodle, as defined above, bred (or backcrossed) to a purebred Poodle. Again, the results are mixed, as this is not the breeding of two “like” dogs. F1B Labradoodles typically are low- to non-shedding if both parents non-shedding (or as much as any dog can be non-shedding) and often have a hair or fleece coat.
Australian Labradoodle: The Australian Labradoodle carries the DNA of the Labrador, Poodle and Cocker Spaniel (American or English). The resulting offspring share characteristics, though some pairings of parent dogs will produce a more mixed litter. An Australian Labradoodle can be created by crossing a Poodle to another Australian Labradoodle, a Cockapoo to a Labradoodle, a Labradoodle to a Cocker Spaniel and the like, resulting in the three-breed combination. Australian Labradoodles and Multigen Australian Labradoodles typically have a non-shedding coat (again, as much as any dog can be non-shedding) if both parents are non-shedding.
Multigen Australian Labradoodle (Multigenerational): A Multigen Australian Labradoodle comes about from the breeding of one Australian Labradoodle to another. Multigen Australian Labradoodles typically have a non-shedding coat (as much as a dog can be non-shedding) if both parents are also non-shedding.
Purebred Australian Labradoodle: The Merriam-Webster Dictionary first defined “purebred” in 1852 as “bred from members of a recognized breed, strain, or kind without admixture of other blood over many generations.” The AKC, meanwhile, requires four generations of like-to-like matings in their foundation service.
The ALAA uses these two references in its definition of a Purebred Australian Labradoodle. Once an Australian Labradoodle has been bred to another Australian Labradoodle in four consecutive matings, it will be considered purebred.
