In fact, there are several layers to Cavapoo F1b cross-breeding that have direct impacts on the outcome.

1. F1b Cavapoos Are Bred Back


F1b Cavapoos are different from standard Cavapoos, also called F1 Cavapoos. An F1 Cavapoo results from breeding a Cavalier King Charles Spaniel with a Poodle, which is what most people expect when picking up a Cavapoo puppy.

F1b Cavapoos have been bred back, meaning these puppies’ parents are one F1 Cavapoo and one of the original breeds – a Poodle or a Cavalier King Charles.

2. Poodles Are Usually One Parent

It can be challenging to distinguish F1bb Cavapoos from F1 and F2 Cavapoos. Put simply, the Poodle is the original breed that mixes with an F1 Cavapoos to create an F1b Cavapoo.

Some people want one parent to be a toy or miniature Poodle, allowing more control over the dog’s size.

If that’s the case, the official name of the resulting breed will be either F1b toy Cavapoo or F1b mini Cavapoo. 

However, in some cases, breeders will back breed an F1 Cavapoo with a Cavalier King Spaniel. Doing so can impact the size and appearance of the breed.

3. F1b Cavapoos Are Very Friendly


In terms of temperament, F1b Cavapoos aren’t that different from F1 Cavapoos. This sub-breed is known to be very friendly. These dogs love their families and people in general. F1b Cavapoo adults do well with children and strangers alike. 

Like F1 Cavapoos, F1b Cavapoos may be apprehensive toward other dogs. But you can manage that with general training and sufficient socialization.

4. They Are Hypoallergenic

One of the main reasons someone would specifically want to breed an F1b Cavapoo over an F1 Cavapoo is its level of hypoallergenic.

F1 Cavapoos are generally considered hypoallergenic dogs because they’re low-shedding, low-drooling animals. 

While there’s technically no such thing as a 100 percent hypoallergenic dog, Cavapoos come pretty close – but not as close as F1b Cavapoos. 

Cavapoos get their hypoallergenic features from their Poodle heritage. Poodles also have low-shedding coats and tend to release fewer allergens into the air, making them excellent pets for those with dog dander allergies. 

Because F1b Cavapoos are typically bred back to include a purebred Poodle again, it can increase the hypoallergenic nature of the mix. 

5. F1b Cavapoos Have Dense Coats


An F1b Cavapoo is a 75/25 mix of Poodle and Cavalier King Charles Spaniel. This mix means the dog will have more Poodle traits, including a Poodle’s naturally thick and curly fur. 

Cavapoos need regular grooming, but an F1b Cavapoo will likely need even more.

They have very dense, curly coats, which makes them more prone to tangles. You must comb or brush them at least once weekly to prevent severe tangles and mats. 

Brushing can also help remove loose, dead hairs caught up in the dog’s curls. Doing so will keep their coats looking nice and shiny between washes. 

6. The Breed Has a Lot of Energy

About 75 percent of this dog breed is Poodle, and Poodles have a ton of energy. Therefore, an F1b Cavapoo is bound to have a good chunk of energy. This dog is a breed for owners and families who can commit to spending plenty of time exercising their dog. 

For a calm and happy dog, you must give this specifical Cavapoo at least a full hour of daily physical activity. This activity can include playing games, walking, or running. Any dog with pent-up energy can get himself into trouble easily. 

7. F1b Cavapoos Are Savvy


Both Poodles and Cavalier King Charles Spaniels are intelligent, affectionate breeds. Cavaliers are super sweet and love nothing more than pleasing their owners. Poodles are often praised for their extreme intelligence and easy training. 

This fact should come as no surprise, considering Cavaliers and Poodles are common show dog breeds. These well-behaved, intelligent creatures can easily learn commands, follow instructions, and pay close attention to their owners’ wishes. 

This back-bred Cavapoo can inherit its smarts from both of its parents. In the end, you should wind up with brains and love to work with. 

But keep in mind that Cavapoos can also be very sensitive. They may not respond well to harsh training and yelling, so keep things light and positive.

This dog will do well with positive reinforcement and consistency – the same as both parent breeds.

8. F1b Cavapoos Are Little

Cavalier King Charles Spaniels are small dogs, so their genes play a role here. On top of that, most F1b Cavapoos come from breeding with a miniature or toy Poodle, which can be 15 inches or shorter. 

Genetics here would tell us that the result of breeding such small dogs will be more small dogs, which would be correct. An F1b Cavapoo that’s full-grown won’t be taller than 15 inches. Healthy adult dogs will weigh a maximum of 25 pounds. 

So, if you’re looking for a small dog breed, the F1b Cavapoo is a fantastic choice.

9. They Have Long Legs


To our point above, it’s a little strange to imagine such a small breed with long legs, but you can expect this type of Cavapoo to have long legs for its body.

This feature mostly concerns the majority percentage of Poodle genes mixed into the breed.

Cavalier Spaniels are naturally short with little legs. While their legs are by no means disproportionate to their bodies, they are shorter in contrast to a Poodle’s legs. 

Poodles have long, thin, graceful legs. Even Miniature Poodles and Toy Poodles have long legs, despite their small size. 

F1b varieties tend to inherit the long leg gene from their Poodle ancestors. The legs don’t increase their overall size or height, but they add elegance to the dog’s look. 

10. F1b Cavapoos May Be Healthier Than Their Parents

Although crossbreeds can potentially inherit health complications from both parent breeds, hybrid vigor can make them more healthy. 

Hybrid vigor is the potential to create offspring that have better biological function than either of their parents.

While the notion still requires more research, it’s been evident in crossbreeds that they can be healthier, live longer, and present with positive traits from their parents.

Although cross-breeding can be dangerous in other ways, one advantage is that this phenomenon can make them better, healthier dogs.

Is cross-breeding harmful to dogs?

Cross-breeding is possible because all types of dogs share enough common DNA to make it possible. And while there are advantages to cross-breeding, there are also drawbacks. 

Cross-breeding isn’t a perfect, predictable science, so it can be challenging to predict the results.

Certain crosses can be dangerous for some breeds. For instance, breeding dogs with significant size differences can lead to dangerous deliveries for females. 

In cross-breeding, you may also introduce more possible congenital health issues. The puppies receive health risks from both breeds instead of one. 

What other dogs are bred with Poodles?
