F1 vs. F1b Cavapoos

What is the difference between F1 and F1b?

What is an F1 Cavapoo?

An F1 Cavapoo is a first-generation cross between a purebred female Cavalier King Charles Spaniel and a purebred male Poodle. At Conner Creek Cavapoos, the mother is always the Cavalier and the father is the Poodle. Their puppies have an estimated 50% Cavalier and 50% Poodle ancestry.

 

What is an F1b Cavapoo?

The “b” stands for backcross, meaning an F1 Cavapoo is bred back to one of the original parent breeds.

 

At Conner Creek Cavapoos, I always pair an F1 Cavapoo mother with a purebred Poodle father. Their puppies have an estimated 25% Cavalier and 75% Poodle ancestry.

 

These percentages describe ancestry, not the recipe for appearance or personality. “75% Poodle” does not mean a puppy will have 75% of a Poodle’s curls, proportions, or personality.

 

The traits a puppy inherits combine to produce its observable appearance, called its phenotype. That appearance varies from puppy to puppy. Choose a puppy with the look you love, rather than choosing a generation you’ve been told will produce that look.

 

Are F1b Cavapoos always curlier?

No. It is very common to see F1b Cavapoos with the softer, wavy appearance people associate with F1 Cavapoos.

 

Coat characteristics depend on the particular gene variants a puppy inherits. Curl and the longer hair around the eyebrows and muzzle, called furnishings, involve different genes. A generation label does not identify a puppy’s combination of those traits.

 

This is why “F1 equals wavy” and “F1b equals curly” are too simplistic.

 

If you prefer a softer wave, don’t automatically exclude F1b puppies. If you prefer a curlier appearance, don’t assume every F1b will have it. Look at the Conner Creek Cavapoos you are most interested in and discuss the coat you like the most with me so I can offer guidance based on my experience!

 

And if you’d like help comparing individual puppies, I can guide you during a FaceTime puppy consultation and answer puppy-specific questions!

 

Will the coat change as the puppy grows?

In my experience with my lines, supported by feedback from families I stay in touch with, the coat tends to become thicker as a puppy matures. I generally see the existing wave or curl remain consistent rather than change into a different pattern.

 

That is an observation about my dogs, not a promise that every puppy’s adult coat will look exactly like its puppy coat. Coat length and grooming also affect the look of the coat throughout a Cavapoo’s life.

 

Do F1 or F1b Cavapoos shed more?

In my lines, both F1 and F1b Cavapoos shed so little that the difference is negligible in everyday life. That reflects my own experience and ongoing feedback from families as their puppies grow into adults.

​

I wouldn’t choose an F1b over an F1 solely because you expect noticeably less shedding. My F1 Cavapoos already offer the minimal shedding many families want. However, low shedding does not mean allergy-free, and neither generation guarantees that someone won’t react.

 

Are F1b Cavapoos smarter or easier to train?

In my lines, both F1 and F1b Cavapoos learn quickly and respond well to training (like the potty bells!). My clients and I sometimes notice F1b puppies catching on a little faster, but the difference is minor, not something I would base a puppy choice on.

 

When choosing a companion, it’s important to discuss how you plan to provide patient teaching, consistency, and opportunities to learn. In my experience, the time and effort a family puts into raising their puppy matter far more to a successful fit than the small learning differences between F1 and F1b Cavapoos.

 

Do F1 and F1b Cavapoos look different?

Sometimes. Some of my F1bs have slightly longer legs and muzzles and more athletic bodies. Others do not show those differences.

 

My clients and I have noticed their agility and enthusiasm for backyard games with the kids and their neighborhood friends. The hoped-for bonus? Kids and a puppy ready for an earlier bedtime!

 

As with the coat, these are possible patterns rather than a dependable way to identify the generation by looking at a dog.

 

If you have a particular appearance in mind, show me what you like. That gives us a more useful starting point, because a generation label provides zero guarantee of that specific look.

 

Should I choose an F1 or an F1b Cavapoo?

My recommendation depends on what your family is looking for.

 

Tell me which qualities matter most, and I can help you compare individual puppies. Generation and sex can be part of that conversation, but neither replaces getting to know the puppy.

 

You don’t need to decide on a generation before deciding what you want in a dog.

 

Frequently asked questions

Can an F1b Cavapoo look like an F1?

Yes. In my breeding lines, I commonly see F1b puppies with the wavy coat appearance buyers associate with F1 Cavapoos. There is overlap in appearance between the generations.

 

Does F1b mean a smaller Cavapoo?

No. The label describes the breeding cross, not a size category.
