F1 vs. F1b vs. Multigen: Decoding the Goldendoodle Coat
The Quick Answer:
Do Goldendoodles shed? It depends entirely on their genetics. Generally, an F1 (50% Poodle) has a wavy coat that may shed lightly, while an F1b or Multigen (higher Poodle percentage) has a curlier coat that is hypoallergenic and non-shedding. At Ironstone, we rely on DNA testing for "Furnishings" to guarantee coat quality, rather than guessing based on generations alone.
The Alphabet Soup: F1, F1b, and Multigen
When shopping for a Goldendoodle, you will see a lot of confusing labels. These codes simply tell you the dog's family tree.
F1 (First Generation): A Golden Retriever bred to a Poodle (50% / 50%).
The Coat: Usually wavy and "shaggy."
Shedding: Variable. Some shed lightly, some don't.
F1b (First Generation Backcross): An F1 Goldendoodle bred back to a Poodle (75% Poodle / 25% Golden).
The Coat: Usually curly or tight waves.
Shedding: Very low to non-existent. Recommended for severe allergy sufferers.
Multigen (Multi-Generation): Two Goldendoodles bred together.1
The Coat: Highly consistent.
Shedding: Breeders can maintain the non-shedding trait effectively here through DNA testing.

It's Not About Percentage, It's About "Furnishings"
This is the secret that many backyard breeders don't know. The generation (F1 vs F1b) is just a guess. The real science is a gene called RSPO2, often called "Furnishings."2
What are Furnishings?
Furnishings are the longer hair on a dog's eyebrows, mustache, and beard.
Furnished (F/F or F/IC): The dog has the "fluffy" look and is low-shedding.
Unfurnished (IC/IC): The dog has a "flat" coat (like a Golden Retriever) and will shed.
At Ironstone, we don't just guess. We test our parent dogs to ensure they carry the proper Furnishings genes so you get the coat you expect.
Grooming Requirements
A non-shedding coat means the hair keeps growing, much like human hair. This is the trade-off for a hypoallergenic dog.
Brushing: Requires brushing 2-3 times a week to prevent matting.
Professional Grooming: Required every 6-8 weeks.
The "Puppy Cut": Most owners keep their dogs in a "teddy bear" clip, which keeps the body short but the face round and fluffy.
Conclusion
Whether you prefer the shaggy look of the F1 or the tight curls of the F1b, understanding the genetics is key. Our goal is to match you with a puppy that fits your home's allergy needs and your aesthetic preferences.
