FIRST GENERATION GOLDENDOODLES - F1
A first generation hybrid Goldendoodle is the product of a Golden Retriever and a Poodle. The term 'Goldendoodle' was first coined by Amy Lane after she bred her first litter of Goldendoodle pups. As first generation hybrids, these dogs have the added health benefits associated to Hybrid Vigour. According to Dr. Kate Schoeffel, Honours Geneticist, Veterinarian and Doodle breeder, "Hybrid vigour is not a theory, it is the name given to describe something that happens repeatedly throughout all species in the animal and plant kingdom. When unrelated breeds of any animal species are mated the offspring in the first generation will be more healthy, fertile, and (in animals) mentally stable than either parent breed. This first F1 (Filial1) generation as the geneticists call it, will be intermediate in characteristics to the parent breeds and the offspring will resemble each other." (See more of her discussion and analysis here: http://www.family-pets.com/genetics.html). For a decreased likelihood of shedding or allergic reactions, owners may wish to consider an F1B Goldendoodle.
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: Moderate-to-light shedding (occasionally
Allergy Friendliness: Usually successful in families with mild allergies. When a family has moderate to severe allergies, a backcross Doodle (F1B) is recommended.
A backcross pup is the result of a hybrid bred back to one of its breeds of origin. From a genetic standpoint a backcross pup is a first generation cross. As breeders are breeding towards non-shedding and allergy friendliness, a backcross Goldendoodle is generally the product of a Goldendoodle bred to a Poodle. The resulting dog is, on average, 1/4 Golden Retriever and 3/4 Poodle. The first generation backcross is close enough in the breeding tree to benefit from hybrid vigour. These puppies are sought-out across the United States due to their delightful temperament, low- to non-shedding coats, and ideal personality for families.
Coat Maintenance: Light to Moderate care
Coat Description: Coat continues to grow in length. Coats
are wavy or curly.
Shedding: Very light to non-shed
Allergy Friendliness: Recommended for families with moderate to severe allergies.
SECOND GENERATION GOLDENDOODLES - F2
A second generation Goldendoodle (F2) is the result of a Goldendoodle bred to a Goldendoodle - and there are very few of these actually bred as the second generation hybrid is genetically the most varied generation possible. F2 Goldendoodles may be 90% Poodle or 90% Golden Retriever, but are more likely to be somewhere in between.
Coat Maintenance: Varies on the coat type
Coat Description: The coat can be a hair coat, wavy coat,
or curly coat.
Shedding: Varies greatly from shedders to non-shedders
Allergy Friendliness: Not recommended for families with allergies, due to the varying coat types. Very unpredictable.
SECOND GENERATION BACKCROSS GOLDENDOODLES - F2B
A second generation backcross pup (F2B) is the result of a Goldendoodle (F1) bred to a Goldendoodle backcross (F1B). Although three generations in the making, F2Bs are technically second generation dogs.
F1: 1st generation pup - Golden Retriever x
F1B: 1st generation pup - Goldendoodle x Poodle
F2: 2nd generation pup - Goldendoodle x Goldendoodle
F2B: 2nd generation pup - Goldendoodle F1B x Goldendoodle
