The terms F1, F1B, and F1BB are used to describe different generations of doodles, including popular breeds like Goldendoodles and Labradoodles. These terms indicate the degree of Poodle ancestry in the dog’s lineage and are crucial for understanding the characteristics and traits of the doodle. Let’s break down what each generation means:

1. F1 (First Generation):

   • Parent Breeds: The first generation, or F1, is a cross between a purebred Poodle and another purebred dog, such as a Golden Retriever or Labrador Retriever.
   • Genetic Makeup: F1 dogs have a 50% Poodle and 50% other breed genetic makeup. This generation typically has a moderate to low shedding coat, but individual dogs may vary.

2. F1B (First Generation Backcross):

   • Parent Breeds: F1B is a backcross, meaning it involves breeding an F1 doodle with a purebred Poodle.
   • Genetic Makeup: F1B dogs have a 75% Poodle and 25% other breed genetic makeup. This generation is more likely to have a hypoallergenic and low-shedding coat due to the increased Poodle influence.

3. F1BB (First Generation Backcross to Backcross):

   • Parent Breeds: F1BB is a further backcross, typically involving breeding an F1B doodle with a purebred Poodle.
   • Genetic Makeup: F1BB dogs have a 87.5% Poodle and 12.5% other breed genetic makeup. This generation is even more likely to have a hypoallergenic and non-shedding coat, as there is a higher concentration of Poodle genes.

Characteristics:

• F1 Doodles: These dogs may have a range of coat types, including straight, wavy, or curly. Shedding can vary, and coat maintenance is usually moderate.

• F1B Doodles: This generation is more likely to have a curly or wavy coat, resembling the Poodle parent. They are often chosen by individuals with allergies or those seeking a low-shedding dog.

• F1BB Doodles: These dogs are more likely to have a coat similar to a purebred Poodle, with tight curls or waves. They are often considered hypoallergenic and have minimal shedding.

It’s important to note that individual dogs within each generation can still vary in terms of coat type, size, and temperament. Additionally, responsible breeding practices and the health of the parent dogs play a significant role in the overall well-being of doodles across different generations. When choosing a doodle, it’s advisable to work with reputable breeders who prioritize health, temperament, and adherence to breed standards.
