F1b Cavapoo – How Does It Differ To An F1?
What exactly is an F1b Cavapoo and how does it differ from an F1 Cavapoo?
It can be confusing because that little ‘b’ can make a huge difference so keep reading as I explain the differences.
An F1 Cavapoo is the result of mating a purebred Cavalier King Charles Spaniel to a purebred Poodle.
The puppies are then 50% Poodle and 50% Cavalier.
An F1b Cavapoo on the other hand requires one of the parent dogs to be an F1 Cavapoo and the other parent dog to either be a purebred Cavalier or a purebred Poodle.
Most of the time, the Poodle is the second parent dog.
The ‘b’ stands for backcross meaning that a first or second-generation Cavapoo has been bred back to a purebred dog. (Cavalier or Poodle)
F1b Reverse Cavapoo
An F1b Reverse Cavapoo is when an F1 Cavapoo is mated with a Cavalier King Charles Spaniel.
This means that the puppies will be 75% Cavalier and 25% Poodle.
The Reverse Cavapoo’s coat will almost certainly resemble the Cavalier and should be straight and wavy with maybe a slight curl.
The characteristics of the Cavalier will be dominant (not a bad thing) and these dogs will shed just like a Cavalier does.
The bonus for Cavalier King Charles lovers is that they can have the look that they love of the Cavalier and hopefully have a healthier dog that will live a longer life due to hybrid vigor.
Buyers need to be careful when buying an F1b Cavapoo making sure that the one parent dog is a Cavalier as some breeders call all F1b Cavapoos ‘Reverse’ even when the purebred parent dog is a Poodle.
How Big Do F1B Cavapoos Get?
The size of the F1b Cavapoo will depend greatly on which type of Poodle was used.
The Toy Poodle is the smallest of the Poodle breed.
They can reach a height of around 10 inches and weigh between 6 and 9 pounds.
The next size up is the Miniature Poodle.
Their height can range between 11 to 15 inches and they can weigh 15 to 17 pounds.
These are the two most common sizes used for breeding Cavapoos the Standard Poodle, being the largest Poodle can reach a height of over 15 inches and average out at around 22 inches.
F1b Cavapoos look almost the same as F1 Cavapoos except that their hair could be curlier and their legs can be longer thanks to the Poodle genetics.
Do F1b Cavapoos Shed?
Being 75% Poodle, the F1b Cavapoo’s coat is more likely to have tighter curls and they should also be low to non-shedding.
They will need more regular trimming than the F1 Cavapoo unless you prefer the longer look.
Breeders have purposely bred F1b Cavapoos for people looking for non shedding dogs making them the perfect companion for those suffering from allergies.
F1b Cavapoo Temperament
Cavapoos are known for their loyal, cuddly, and loving temperaments no matter which generation they are.
The F1b Cavapoo is no exception.
They are friendly, sweet, and social dogs.
It is important to socialize your puppy when it is very young.
This applies to all dogs, no matter the breed or mix breed.
Cavapoos respond well to positive reinforcement which needs to be started immediately.
This will ensure that you raise a well-balanced pup and eliminate any timid or bad behavior going forward.
Temperament is not just a result of genetics although it does play a part.
The way that you train and behave with your Cavapoo will also be a huge determining factor as to how their personalities will develop.
F1b Cavapoos can be more active and are highly intelligent.
They need to have mental stimulation to avoid them getting into mischief and a daily walk is needed to satisfy their active nature.
F1b Cavapoo Full-Grown
An adult f1b Cavapoo will have a curly coat because of the dominance of the Poodle gene.
They should look just like teddy bears which is the typical look of the Cavapoo.
They can come in a range of colors just like any F1 Cavapoo and as mentioned before, their legs can be longer than usual.
Which Generation Cavapoo Is Best?
The most common Cavapoo is the F1 Cavapoo because it is 50% Poodle and 50% Cavalier.
They are a good mix of both breeds in terms of health and temperament.
However, there is a chance that the F1 Cavapoo can be a shedder.
It depends on which coat the puppy inherits.
If the puppy has more of a straight wavy coat then it will shed just like a Cavalier will.
On the flip side, if the coat is curly like a Poodle then the puppy will be low to non shedding.
An F1b Cavapoo being 75% Poodle should not shed or hardly shed at all and is favored by people who are allergic to dogs.
This is not a guarantee that they will not react to their F1b Cavapoo but it does give them the best chance of this not happening.
Conclusion
The F1b Cavapoo is just as adorable as an F1 Cavapoo so either mix breeds are fantastic family pets.
Below is a summary of the differences.
| F1 Cavapoo | F1b Cavapoo | |
| Size | 10 – 15 inches | 10 – 15 inches |
| Color | Multiple Colors | Multiple Colors |
| Coat | Curly/Wavy/Straight | Curly/Tight Curls |
| Activity Level | Moderate | Can be high energy |
| Hypoallergenic | Can be depending on coat type | Less of a risk for allergy suffers |
| Price | Same as F1b | Same as F1 |
Question; Is the F-1b Cavapoo smarter and easier to train than their F1 Cousins? What is the difference in tempament ?
Please kindly advise.

HI Richard,
The F1b normally has three quarters poodle in their genes. That is if a poodle has been mated to an F1 Cavapoo.
Poodles are very smart dogs, highly intelligent and super trainable.
A lot though depends on how you train their offspring.
You must only use positive reinforcement and start training the minute your puppy comes home.
Being very smart comes with it’s own challenges though as poodles can be very anxious and stubborn if not trained correctly and given enough exercise.
Temperament wise – every puppy is unique and in the same litter you can get a great variance in temperament.
Generally though, the F1b’s temperament should be very similar to an F1.
If you are looking for a specific temperament then I would suggest working with a reputable breeder that will match their puppies with the correct families.
If you are looking for a laid back, placid puppy then tell the breeder what you want and a good breeder will match you to that puppy.
You would need to be flexible and take whatever color or gender that puppy is if temperament is your top priority.
If you are part of the Facebook Group then you are welcome to ask the same question inside the Group.
I know a few of the members do have F1b Cavapoos and you can then get their feedback.

I have a f1b cavapoo and she is very sweet, attached, very active, very smart and we love her so much. We are 81 and 78 and she was a gift from our daughter. We
have always had shih tzus and very laid back — our Daisy is not! I am wondering how large she will get??
Hi There,
First of all, congrats on your new furbaby :))
F1b Cavapoos are 3/4 Poodle and 1/4 Cavalier King Charles Spaniel.
This means that the final size of your puppy will be heavily determined by which size Poodle was used in the matings.
The final size can be anything between 9 to 15 inches in height and could even end up being bigger.
Final weight can also vary greatly – 6 to 17 pounds.
Cavapoos are a mix breed so nothing is guaranteed and in each litter there can be small and larger puppies:))
So, anything is possible.
Mum is F1b Cavapoo and dad is cavalier King Charles spaniel . What prevent is poodle and cavalier ?
An F1b Cavapoo is when one parent is an F1 cavapoo (50% Cavalier and 50% Poodle) and the other parent is either a purebred poodle or a purebred Cavalier.
The puppies from this mating are considered F1b.
If the Poodle has been used then the puppies will be 75% Poodle and 25% Cavalier.
If a Cavalier is mated to an F1 Cavapoo then the puppies will be classified as F1b Reverse Cavapoos. (75% Cavalier and 25% Poodle)
An F1B Cavapoo mated to a Cavalier or Poodle will result in F1bb puppies.
If you are using a Cavalier for this mating then the resulting puppies should end up being 85% Cavalier and 15% Poodle and they will look just like a Cavalier.
They will shed.
I just recently got a f1b cavapoo puppy (mum is a cavapoo, not sure if it’s a f1/f1b, dad is a toy poodle) that is 12 weeks 5days old. He weighs about 900grams. I am curious how big he will get. He has a pretty straight apricot colour hair right now. Will the colour change and the hair get more curly like a teddy type?
Thank You 🙂
It is quite difficult to determine what his final weight will be but I am guessing that he will remain quite small.
As far as color is concerned, a lot of cavapoos do fade as they age due to the poodle fading gene.
You can ask the breeder if the father has been tested for this or not to give you a better idea.
F1b cavapoos should be quite curly as they are 3/4 poodle and only 1/4 Cavalier.
The curly hair could start to develop when his adult coat replaces his puppy coat but only time will tell.
Really helpful thanks, although I’m still undecided on f1 or f1b. Probably because there are pros & cons & I don’t have very strong feelings either way. It’ll no doubt come down to what’s available within a reasonable distance when I can adopt which is just before Xmas, I’ll keep thinking until then ?. Thanks again
Hi Sharon,
The big difference between the two is that a F1b has more poodle in it’s genes so the resulting pups tend to shed less or not at all.
Both the f1 and f1b cavapoos are gorgeous so you won’t go wrong in choosing one of them :))
