Cavapoos are known for their beauty, temperament, and hypoallergenic coats. But did you know only certain generations of Cavapoos are actually hypoallergenic? 

There are several generations of Cavapoos, F1, F1b, F1bb, F2, F2b, etc. So what do these mean? What’s an F1b Cavapoo? And why is it the most favored generation?

In short, an f1b Cavapoo is also known as a first-generation backcross. This occurs when a Cavapoo is bred back with a Poodle. Thus, resulting in a Cavapoo with 75% Poodle and 25% Cavalier. In addition, you can also have an f1b reverse Cavapoo which is a Cavapoo bred backcrossed with a Cavalier King Charles Spaniel.

So what’s special about the F1b Cavapoo versus the other generations?

In this blog post, we will cover the F1b Cavapoo generation in detail and compare it to some of the other generations. We will also discuss the F1b Cavapoos’ physical appearance, size, colors, temperament and answer other frequently asked questions.

Let’s dive in.

F1b Cavapoo

The Cavapoo Generations

The Cavapoo is a cross between the Cavalier King Charles Spaniel and the Poodle. However, Cavapoos can be bred in several different ways, which is why there are generations of Cavapoo.

It’s the same reason that not all Cavapoos are created equal. Some may have more Poodle in their genes, and others may have more Cavalier King Charles Spaniel.

What Foes The “F” Mean In The Cavapoo Generations?

You’ve probably seen a few generation names such as F1, F1bb, or F2b Cavapoo, but what does the ‘F’ mean?

The ‘F’ in the Cavapoo generations stands for ‘filial.’ The word filial means “generation after the parental generation.” So an F generation Cavapoo is just a generation of offspring from the Cavalier King Charles Spaniel and a Poodle.

Any number following the F, such as 1 or 2, refers to the generation number. So F1 would mean generation one and F2 generation two.

The letter ‘B’ in generation names refers to a backcross. So, for example, an F1b Cavapoo is the first-generation backcross. Likewise, an F1bb would be considered a first-generation backcross backcross.

Genetics Of Cavapoo Generations

Here is a basic breakdown of the genetics you can expect to find in each generation.

  • F1 Cavapoo: 50% Poodle & 50% Cavalier King Charles Spaniel
  • F1b Cavapoo: 75% Poodle & 25% Cavalier King Charles Spaniel
  • F1b Reverse Cavapoo: 75% Cavalier King Charles Spaniel & 25% Poodle
  • F1bb Cavapoo: 87.5% Poodle & 12.5% Cavalier King Charles Spaniel
  • F2 Cavapoo: 50% Poodle & 50% Cavalier King Charles Spaniel
  • F2b Cavapoo: 62.5% Poodle & 37.5% Cavalier King Charles Spaniel
  • F2bb Cavapoo: 81.25% Poodle & 18.75% Cavalier King Charles Spaniel

What Is An F1b Cavapoo?

F1b Cavapoo

An F1b Cavapoo is the first-generation backcross. This occurs when a Cavapoo is bred back with a Poodle. Thus, resulting in a Cavapoo with 75% Poodle and 25% Cavalier.

The F1b backcross generations exist to reduce negative traits that may be present in the F1 generation Cavapoos. F1b generations are also much easier to predict regarding their physical appearance and temperament.

F1bb Cavapoos

The F1bb Cavapoos are a double backcross. In other words, an F1b Cavapoo is bred with a Poodle. This leaves the breed with 87.5% Poodle genes and 12.5% Cavalier genes on average (though Poodles tend to be used more often).

The F1bb-Cavapoos were designed to reduce undesirable characteristics of F1b-generation Cavapoos. However, most of the time, F1bb types look identical to Poodles. This might detract from the distinctiveness of the Cavapoos.

What’s An F1b Reverse Cavapoo?

F1b reverse Cavapo

An F1b reverse Cavapoo is similar to the F1b. However, the Cavapoo is bred with a Cavalier King Charles Spaniel instead of a Poodle. The result is an F1b Cavapoo that’s 75% Cavalier and 25% Poodle. As a result, reverse-Cavapoos are much less common than other types of Cavapoos.

What Does An F1b Cavapoo Look Like?

Since the F1b Cavapoo is 75% Poodle and 25% Cavalier, its appearance and build will be very similar to a Poodle. 

Their eyes are typically dark brown and round, and their ears are floppy. Their muzzle is more pointed than the Cavalier’s but not as extreme as a Poodle’s.

A Cavapoo with a round face, floppy ears, and a non-shedding coat is the most sought after. An F1b generation Cavapoo usually has a curly coat like the Poodle but could have moderately wavy hair too. Their coats are generally medium length and soft to the touch.

Here are some of the most popular F1b-generation Cavapoo coat colors:

  • Black
  • White
  • Tan
  • Ruby
  • Apricot,
  • Blue
  • Brown
  • Grey
  • Silver

How Big Will A F1b Cavapoo Get? (Weight & Height)

F1b Cavapo

The F1b Cavapoo can come in different sizes depending on the Poodle used for breeding. 

Poodles can be standard, miniature, toy, and teacup sizes. So this can play a role in the size of the F1b Cavapoo. For example, suppose mini Poodle breeds with Cavapoo. In that case, the offspring will likely be much smaller than if a standard poodle was used.

In addition, most of the generations of the Cavapoo will be around the same weight and height. However, since the F1b Cavapoo has slightly more Poodle, they can be slightly taller.

Here are the standard sizes for an f1b Cavapoo:

Standard F1b Cavapoo

The standard F1b Cavapoo comes from breeding a Cavalier King Charles Spaniel with a Standard Poodle.

A standard F1b Cavapoo can range from 18+ inches (45.7cm) and weigh 25 to 40 pounds (11.3-18.2kg).

Miniature F1b Cavapoo

The miniature F1b Cavapoo comes from breeding a Cavalier King Charles Spaniel with a Miniature Poodle.

A miniature F1b Cavapoo can range from 12 to 18 inches (30-40cm) and weigh 20 to 30 pounds (9.1-13.6kg).

Toy F1b Cavapoo

The toy F1b Cavapoo comes from breeding a Cavalier King Charles Spaniel with Toy Poodles.

A toy F1 Cavapoo can range from 10 to 12 inches (25.4-30.5cm) and weigh 13 to 25 pounds (5.8-11.3kg).

Teacup F1b Cavapoo

The teacup F1b Cavapoo comes from breeding a Cavalier King Charles Spaniel with teacup Poodles.

A teacup F1 Cavapoo can range from 8 to 10 inches(20.3-25.4cm) and weigh 18 to 15 pounds (3.6-6.8kg).

How Much Do F1b Cavapoos Shed?

Regarding shedding, the f1b Cavapoo, falls in the non-shedding category. However, there is no such thing as a dog that doesn’t shed at all. There are just dogs that shed very little.

Poodles are known for being non-shedding, and since the F1b Cavapoo is 75% Poodle, you can expect them to carry this trait.

When it comes to grooming, the F1b-generation Cavapoo will need to be professionally groomed every few months, just like a Poodle is. However, they don’t require much brushing.

You should also expect to brush your FIb Cavapoo at least once weekly to prevent matting and tangles.

As for bathing, teeth cleaning, ear cleaning, and nail trimming. All Cavapoos will have similar needs. Cleaning and trimming should be done when needed, which for most Cavapoos will be every few weeks. Bathing can be done monthly unless they get dirty more often.

Are F1b Cavapoos Hypoallergenic?

F1b Cavapoo

The F1b Cavapoo is considered hypoallergenic. This is because they are 75% Poodle which is a hypoallergenic parent.

So the F1b Cavapoo will not produce as much dander as other dogs, which is what people with allergies react to. However, no dog is 100% hypoallergenic, and there is always a chance that someone could be allergic to them.

How Long Do F1b Cavapoos Live?

The f1b Cavapoos lifespan is typically around 9 – 14 years. However, these dogs will often live slightly longer if they are made with miniature or toy poodles. 

Do F1b Cavapoos Have Any Health Issues?

F1b Cavapoo is bred with two somewhat healthy purebred dogs. However, they are still susceptible to some health problems that can be passed down by their Poodle and Cavalier Parents.

Here is a list of the F1b Cavapoo’s most common health concerns:

  • Luxating patellas
  • Hip dysplasia
  • Mitral valve disease 
  • Epilepsy
  • Progressive retinal atrophy,
  • Entropion
  • Cataracts 
  • Glaucoma

Are F1b Cavapoos Easy To Train? 

F1b Cavapoos are not only quick learners, but they also take great joy in making their family happy. In addition, they love being around children and other animals, which makes them ideal pets for any home.

They are also an excellent choice for first-time dog owners.

Since their Poodle parent is one of the most intelligent dog breeds, the f1b Cavapoo has no problem learning commands and tricks. They also excel in obedience and agility training.

However, Since the F1b still has 25% Cavalier in their genes, some Cavapoos may be a little more stubborn and difficult to train. But, with patience and consistency, most f1 Cavapoos will be able to learn most things you want to teach them.

F1b Cavapoo Temperament & Behavior

F1b Cavapo

Cavapoos are intelligent, loving, and pleasant with people, making them suitable for families with children or those who have never owned a dog before. Aside from their coat that may need special grooming, they are very low-maintenance dogs.

If they are left alone for lengthy periods, they are likely to develop separation anxiety. This might be demonstrated in several ways, including barking, howling, pacing, urinating in the house, and breaking furniture.

The F1b Cavapoo is a high-energy dog breed that loves to play and run around. A daily walk may not be enough for this breed. They will need some type of activity or exercise to burn off all their energy.

They need around 2 hours of exercise every day. This could be a combination of walks, runs, playing fetch, or any other type of activity that will keep them mentally and physically stimulated.

Make sure to offer them plenty of interesting toys and puzzles to keep their minds occupied.

Do F1b Cavapoos Bark A Lot?

The F1 Cavapoo is a moderate barker. However, they mostly bark for a reason, not simply because they want to. They may bark in order to get something, such as to go outside, to play, or to get a toy.

Do F1b Cavapoos Like To Cuddle?

The F1b-generation Cavapoo is friendly and affectionate with their humans. If you are looking for a dog that will be your best friend and provide you with endless amounts of cuddles, the F1b Cavapoo is a great choice.

Just keep in mind they can be a tad clingy when wrongfully trained and may suffer from separation anxiety if left alone for too long.

Are F1b Cavapoos Good With Kids?

F1b Cavapoos are great with kids! They are gentle, tolerant, and patient, making them the perfect playmate for your children. Cavapoos need plenty of socializing and training, but they pick up fast on how to interact appropriately with children of all ages.

F1b Cavapoos are friendly and social with other dogs. However, as with all dogs, they will still socialize to learn the proper ways to play and interact with others. 

Are F1b Cavapoos Good With Strangers?

F1b generation Cavapoos are friendly with strangers. They will greet guests with excitement and are not known to be shy or aggressive. Cavapoos are social dogs that thrive on companionship.

Are F1b Cavapoos Good Apartment Dogs?

The Fb Cavapoo is a good apartment dog. They are not too active indoors and don’t require a lot of space. As long as they get daily walks or playtime outside, they will be happy to live in smaller spaces.

What Do F1b Cavapoos Eat?

F1b Cavapoo puppy

The F1b Cavapoo is a very high-energy dog due to it being 75% poodle.

The food requirements of an F1 Cavapoo will vary depending on their age, size, level of activity, and health. The ideal ratio varies from dog to dog and depends on the animal’s condition. However, in general, dogs need 10-18% of their calories from protein and 5.5-8% from fat. The amount of carbs in your pet’s meal is based on his size and age, as well as any medical conditions he has.

The diet of a dog should be based on high-quality dry food. You may add wet or raw food or prepare your own meals, but this is the expensive route. High-quality dry food is all a dog needs to live a happy and healthy life.

Here are some of the food brands recommended by our veterinary consultant, Dr. Littlejohn:

Commercial Dry & Wet Food

Raw Food

How Much Do F1b Cavapoos Cost?

The Average F1b Cavapoo price is roughly $2000 to $5000. Prices vary depending on the breeder, coat type, size, color, and eye color.

For example, if you want an F1b miniature or toy Cavapoo, the cost averages $2500 to $5000. Generally, smaller dogs are more expensive than larger dogs.

In addition, any rare coat colors or patterns will be more expensive than the standard Cavapoo coat colors.

Other Cavapoo Generations Compared To The F1b

F1 Cavapoo

The f1 generation Cavapoo, or the first cross-generation, is a dog that inherits half Poodle and half Cavalier King Charles Spaniel genes.

When genes are split fifty-fifty, they can manifest various characteristics from both parents. It’s the same reason siblings may appear so different even though they have the same mother and father.

The physical appearance of an F1 Cavapoos is impossible to predict because they could take more after either the poodle parent or the Cavalier parent.

F2 Cavapoo

F2 Cavapoo

An F2 generation Cavapoo is a second generation cross. This is a cross between two F1 Cavapoos. This means an F2 Cavapoo will be composed of 50% Cavalier and 50% Poodle.

This results in a Cavapoo with the same genetic makeup as an F1-Cavapoo. However, the F2-Cavapoos are even more unpredictable than the F1 Cavapoos. You are basically rolling the dice when getting an F2-Cavapoo.

F2b Cavapoo

An F2b Cavapoo is a second-generation backcross. They are bred from an F1 Cavapoo mating with an F1b Cavapoo. In other words, an F2b Cavapoo is 37.5% Cavalier King Charles Spaniel and 62.5% Poodle.

F3 Cavapoo

The last Cavapoo generation I will mention is the F3.

An F3-generation Cavapoo is the first of many multi-generation Cavapoos. Multi-gene Cavapoos can also be called F4, F2bb, and many others. The F3 Cavapoo happens in a few different ways. For example, you can breed two F2 Cavapoos or two F1B Cavapoo.

This results in offspring being easier to predict when this far into generations. The Percentage of genes from each parent will differ depending on how the generation was formed.

Final Thoughts

In conclusion, the F1b Cavapoo is a great family companion. They are easy to train, intelligent, and have a gentle temperament. Cavapoos are low-maintenance dogs, but they do require a lot of exercise.

Suppose you’re looking for a small to medium-sized dog breed that doesn’t shed and is hypoallergenic. In that case, the F1b Cavapoo is the best generation Cavapoo for you.

The other generation that would be the closest match to the F1b is the F1bb, F2b, and F2bb. This is because they all get most of their genes from the Poodle parent. So they will all have similar temperaments and looks.

As for the other Generations, they will have more variability in looks and temperament since they get an equal mix of genes from both parents.

So if you don’t care for the high energy or hypoallergenic coat, you may want to look into the other generations (F1, F1b reverse, F2, or F3).

Otherwise, all Cavapoo generations make great family pets. So it really just boils down to preference.
