Understanding Generations

What Does F1, F2, and F1B Mean?

The “F” in doodle generations stands for “Filial,” a genetics term meaning generation in relation to the parents. It simply tells you how many generations away a litter is from the original purebred cross.

• F1 (First Generation): A 50/50 mix — one purebred Poodle and one purebred Old English Sheepdog.

• F2 (Second Generation): Both parents are F1 Doodles.

• F1B (First Generation Backcross): An F1 Doodle bred back to a purebred Poodle, making the puppies roughly 75% Poodle and 25% Old English Sheepdog.

The “B” stands for Backcross, meaning one parent was bred back to a purebred — often to strengthen coat consistency or allergy-friendly traits.

Each generation brings its own unique blend of personality, coat texture, and charm — and at Life Unleashed Farm, we carefully choose pairings to bring out the very best in health, temperament, and family companionship. ❤️

Understanding Doodle Generations

Not all Doodles are the same — each generation carries its own blend of traits, coat types, and predictability. Here’s a quick guide to help you understand what those “F” numbers mean:

• F1 (First Generation) – The classic Doodle!

• A 50/50 mix of a purebred Poodle and a purebred partner breed (like an Old English Sheepdog).

• F1s tend to have that adorable, slightly shaggy coat and a balanced mix of both parent breeds in looks and personality.

• F1B (Backcross Generation) – 75% Poodle, 25% partner breed.

• An F1 Doodle bred back to a purebred Poodle.

• These pups often have curlier, lower-shedding coats — great for families with mild allergies or those who prefer a more Poodle-like coat texture.

• F2 (Second Generation) – Both parents are F1 Doodles.

• This pairing brings consistency in temperament and a fun blend of coat types, from wavy to curly.

• F2s are known for their social, easygoing nature and balanced genetics.

• F2B (Second Generation Backcross) – An F1 Doodle bred to an F1B or Poodle.

• These puppies can have the most hypoallergenic coats of all generations, with predictable curl and minimal shedding.

• F2Bs often carry the strong intelligence of the Poodle with the loyalty and calm of the partner breed — the best of both worlds.
