A Complete Guide to F1, F1b, and F2 Cavapoos
Puppy Generations
Quick answer: An F1 Cavapoo is 50% Cavalier and 50% Poodle, an F1b Cavapoo is an F1 bred back to a Poodle (about 75% Poodle), and an F2 Cavapoo is two F1 Cavapoos bred together. F1 puppies have the most hybrid vigor, F1b puppies usually have the curliest, lowest shedding coats, and F2 puppies have the most variety in coat and look. If allergies are a concern, F1b or multigenerational Cavapoos are usually the best choice.
If you’ve been interested in Cavapoo puppies, you’ve probably come across terms like F1, F1b, and F2. But what F1, F1b, and F2 mean for your puppy can make a big difference in coat type, health, and personality. Understanding these generation labels helps you make an informed decision when choosing your furry companion.
Let’s break it down in a simple way, so you can pick the best Cavapoo for your family.
What Is an F1 Cavapoo?
An F1 Cavapoo is a first-generation cross between a purebred Cavalier King Charles Spaniel and a purebred Poodle. This 50/50 mix often gives you the best of both worlds:
• Wavy, low-shedding coat (but not always hypoallergenic)
• Balanced personality: friendly, affectionate, and smart
• Strong hybrid vigor, meaning better health due to genetic diversity
These puppies are often ideal for first-time dog owners looking for an even mix of traits from both parent breeds.
What Is an F1b Cavapoo?
An F1b Cavapoo is a backcross. This means an F1 Cavapoo is bred with a purebred Poodle (most commonly). The result? A Cavapoo that’s 75% Poodle and 25% Cavalier.
This generation is perfect for families concerned about allergies or shedding, because:
• Coats are curlier and more hypoallergenic
• Less shedding, great for people with mild allergies
• Still retains Cavapoo charm, just with a little more “Poodle” influence
If a non-shedding coat is a must-have, an F1b might be your best pick.
What Is an F2 Cavapoo?
An F2 Cavapoo is the result of breeding two F1 Cavapoos. This second-generation mix can be a bit more unpredictable in terms of appearance and coat type:
• Wider variety in coat textures, from straight to curly
• Possible variation in shedding depending on genetics
• Size and temperament similar to F1, but a little less predictable
F2 Cavapoos can be a great fit for families who are flexible about coat type, or who have experience with doodle breeds and are happy with a little variety.
What About F1bb, F2b and Multigen Cavapoos?
F1bb: An F1b Cavapoo bred back to a Poodle again, making the puppies about 87.5% Poodle. These usually have very curly, very low shedding coats.
F2b: An F1 Cavapoo bred to an F1b Cavapoo. These puppies are about 62.5% Poodle and often have wavy to curly coats.
Multigen: Cavapoos from three or more generations of Cavapoo to Cavapoo breeding. Good multigen breeders select for consistent coats, size and temperament, so these puppies are often the most predictable.
Which Cavapoo Generation Sheds the Least?
In general, the more Poodle in the mix and the curlier the coat, the less a Cavapoo will shed. From most shedding to least, most families see F2, then F1, then F2b, then F1b, with F1bb and curly multigen Cavapoos shedding the least. Every puppy is an individual, so ask your breeder about each puppy's coat. Learn more in Are Cavapoos Hypoallergenic?

FAQ: Cavapoo Generations
#1 Which Cavapoo generation is best for allergies?
The F1b Cavapoo is generally best for allergy sufferers due to its higher percentage of Poodle genetics, making it more hypoallergenic.
#2 Are F2 Cavapoos more unpredictable?
F2 Cavapoos can vary more in coat and appearance, but reputable breeders work hard to maintain consistency and quality.
#3 How do I know which generation is right for me?
Think about your family’s needs. Especially allergies, grooming tolerance, and coat preferences. A breeder can help guide your decision.
#4 Does the generation change a Cavapoo's size?
Size depends mostly on the size of the Poodle used. Toy, Mini and Standard Poodles produce smaller or larger Cavapoos in every generation. See our Cavapoo size guide.
#5 Are F1 Cavapoos healthier?
F1 Cavapoos have the most hybrid vigor because their parents are two different breeds. But health testing of the parents matters much more than generation, so always ask your breeder about heart, eye and knee testing.
