The Ultimate Guide to F1b vs. F1bb Goldendoodles
Choosing the right companion is a journey of love, especially when allergies are part of the equation. At The Doodle Nook, we specialize in the most hypoallergenic generations to ensure every family can experience the joy of a Goldendoodle.


Understanding the F1b Generation
The “b” in F1b stands for Backcross. This generation is created by breeding a first-generation (F1) Goldendoodle back to a purebred Poodle. This strategic breeding is designed to “intensify” the Poodle’s desirable traits—specifically their non-shedding coat and high intelligence.
- Genetic Makeup: Approximately 75% Poodle and 25% Golden Retriever.
- Coat Variety: Coats can range from soft waves to loose curls.
- Allergy Friendliness: Excellent for families with mild to moderate allergies.
The F1bb: Our Hypoallergenic Specialty
The F1bb is the result of breeding an F1b Goldendoodle back to a purebred Poodle once again. This is the generation we pour our hearts into at The Doodle Nook because it offers the highest level of predictability for coat type and allergy success.
- Genetic Makeup: Approximately 87.5% Poodle and 12.5% Golden Retriever.
- Coat Type: Consistently curly and plush, trapping dander effectively.
- The Gold Standard: The most hypoallergenic version of the Goldendoodle.
Mastering Doodle Grooming
The Essential Tool Kit
To maintain these high-poodle percentage coats, you need the right tools. We recommend:
- Slicker Brush (Long Pin): Essential for F1bb curls to reach the skin and break up mats.
- Metal Greyhound Comb: The “truth teller”—if this can’t slide through the coat, there’s a mat starting.
- Dematter Tool: For F1b wavy coats to remove loose undercoat hair.
Owner’s Role (Daily/Weekly)
- Line-brushing 3x weekly.
- Wiping paws and sanitary areas.
- Checking for “hidden” mats in armpits and behind ears.
Groomer’s Role (Every 6-8 Weeks)
- Deep cleaning bath and blow-out.
- Full body haircut and styling.
- Nail dremeling and ear plucking.
Seasonal Style Guide
Spring/Summer: The “Summer Cut” or “Sport Cut.” Keep it short (1/4 to 1/2 inch) to prevent overheating and make cleaning up after outdoor adventures easier.
Fall/Winter: The “Teddy Bear Cut.” Keep the coat longer (1-2 inches) for warmth, but remember: longer hair requires daily brushing to prevent snow-clumping and matting.
Which Generation Fits Your Lifestyle?
Choose F1b If…
You prefer a shaggy, wavy look and have mild allergies. Great for the classic “doodle” aesthetic.
Choose F1bb If…
You have severe allergies or asthma. You want the highest guarantee of a non-shedding, curly coat.
