One of the most common points of confusion regarding Goldendoodles and Labradoodles is the generation number used to describe a new litter of puppies – the most common being F1, F1B, F2, or F2b. Although it might seem trivial, the generation tag of a Goldendoodle or Labradoodle can have an impact on several of it’s characteristics, especially shedding. So, if you or your family members have allergies, and want your doodle to be hypoallergenic, it’s important to understand the differences between doodle generations.
F1 Goldendoodles & F1 Labradoodles
First generation Goldendoodles or Labradoodles are identified with the letters “F1.” These are the product of a pure retriever bred with a pure poodle, making the resulting doodle 50% poodle and 50% Golden or Labrador retriever. F1 doodles possess all of the traits that make Goldendoodles and Larbadoodles such desirable dogs. This includes marked intelligence, a loving demeanor, and hypoallergienic qualities. However, it is important to note that some most F1 Goldendoodles and Labradoodles shed lightly to moderately, so are better for homes with only slight or moderate allergies. F1 doodles tend to have a shaggy or wavy coats, but can occasionally have a very curly coat.
F1B Goldendoodles & F1B Labradoodles
When an F1 doodle is cross-bred with a poodle, the term “F1B” is used to describe resulting offspring. An F1B Goldendoodle or F1B Labradoodle is 25% retriever and 75% poodle. This generation has become the most popular generational breed largely because F1B Goldendoodles and F1B Labradoodles are non-shedders 99% of the time, thus making them the most hypoallergenic of all the doodle generational breeds. Because of this this, F1Bs are the best option for families with moderate to severe allergies. Even though F1B doodles are technically 75% poodle, they still benefit from the phenomenon of hybrid vigor and are known to exhibit the same favorable personality traits and behaviors as F1 doodles (with the exception of shedding, as mentioned above).
As for coat types, F1B doodles tend to showcase more variety and can range from long and wavy to short and curly. F1B doodles also exhibit the greatest color variation, giving rise to apricots, champagne, and red colors.
F2 Goldendoodles & F2 Labradoodles
Second generation Goldendoodles and Labradoodles, known as F2, are the offspring of two F1 doodle parents. They are are equal parts poodle and retriever and have similar qualities as the F1 doodles. For example, they are more likely to lightly shed than the F1B doodles.
F2B or multigenerational Doodles
This type of doodle is a second generation backcross. This means an F1 doodle was bred with an F1B doodle. This generation of doodle is less common than the other generation breeds, but will still work well for families with moderate allergies because they are generally non-shedding.
