One of the most common points of confusion regarding Goldendoodles 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 can have an impact on several of its 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.
First generation Goldendoodles are identified with the letters “F1“. These are the product of a pure retriever bred with a pure standard doodle, making the resulting doodle 50% Poodle and 50% Golden Retriever. F1 doodles possess all of the traits that make Goldendoodles such desirable dogs. This includes marked intelligence, a loving demeanor, and hypoallergenic qualities. However, it is important to note that most F1 Goldendoodles shed lightly, so are better for homes with only slight to moderate allergies. F1 doodles tend to have a shaggy or wavy coat, but can occasionally have a curly coat.
F1B Goldendoodles (& Minidoodles!)
When an F1 doodle is cross-bred with a poodle, the term “F1B” is used to describe resulting offspring. An F1B Goldendoodle is 25% Golden Retriever and 75% Poodle. This generation has become the popular generational breed largely because F1B Goldendoodles are non-shedding (99% of the time), thus making them the most hypoallergenic of all the doodle generational breeds. Because of 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 the exhibit the same favorable personality traits and behaviors as F1 Goldendoodles (with the exception of shedding, as mentioned above). The Poodle may not be standard but can be miniature/toy – producing a MINI Goldendoodle (Minidoodle). The Minidoodle can weigh 15-35 lbs.
Second generation Goldendoodles, known as F2, are the offspring of two F1 doodle parents. They are equal parts Poodle and Golden Retriever and have similar qualities to F1 Goldendoodles. For example, they are more likely to lightly shed than F1B doodles.
F2B | Multigenerational Goldendoodles
This type of doodle is a second generation backcross. This means an F1 doodle was bred with an F1B doodle. This generation of Goldendoodle is less common than other generation breeds, but will still work well for families with moderate allergies because they are generally non-shedding.
