Cavapoo Full Grown – How Big Does A Cavapoo Get?

Cavalier King Charles Spaniels are bred to either a miniature or a toy poodle in order to achieve the small and lovable Cavapoo.

A Cavapoo full grown will typically weigh between 12 to 25 pounds, which places them in the category of being a small to medium breed of dog.

Depending on the type of poodle that was used in the breeding process, a typical Cavapoo will reach a height of between 9 and 14 inches.

Despite the fact that both Poodles and Cavalier King Charles Spaniels are considered to be toy breeds, the size of the Cavapoo will be heavily influenced by the size of the father Poodle.

When Is A Cavapoo Full Grown?

After a year, Cavapoos are considered to have reached their full size and are full grown.

However, a number of factors, including the parent’s genetics, diet, level of physical activity, and health, may have an impact on their size.

In comparison to larger breeds, the Cavalier King Charles Spaniel reaches full maturity in a very short amount of time.

Poodles, for example, mature the fastest of all breeds.

It typically takes both mini and toys 6-7 months to reach maturity.

All Cavapoos reach full maturity on average at about one and a half years of age, however, some of the smaller Cavapoos may do so sooner.

At What Age Are Cavapoos Sexually Mature?

Female Cavapoos typically experience their first heat cycle between the ages of 6 and 8 months.

This means that it is possible for your dog to be sexually mature before it has finished growing.

You need to be extra careful during this time frame and keep checking if your puppy has started her first heat cycle.

It is not always noticeable.

If she has started her heat cycle then it is best to stop taking her for walks and to separate her from any male dogs that are at home.

The smell of her heat cycle will drive a male dog nuts and he will do anything he can to get to her.

It is vitally important that she does not become pregnant as she is not yet physically or mentally ready to have a litter.

She has not fully developed yet and being pregnant at a young age can be very detrimental to her health.

It is for this reason that veterinarians are ready to perform sterilization procedures on small breed dogs, such as Cavapoos, as early as six months of age.

Size Of A Full Grown Cavapoo

Your Cavapoo puppy’s parents’ size will be the best indicator of how big your Cavapoo will grow.

The size range for a Cavalier King Charles Spaniel is between 12 to 13 inches tall and they can weigh up to 18 pounds.

Teacup Cavapoo

Teacup Cavapoos are a smaller version of the already small Cavapoos.

They are a result of selective breeding of the smallest Cavapoos, which results in a smaller adult size.

Teacup Cavapoos weigh between 5 and 10 pounds and stand up to 9 inches tall at the shoulder.

It’s important to note that Teacup Cavapoos are not a separate breed but are a result of breeding smaller Cavapoos.

The breeding process involves selecting the smallest Cavapoos and breeding them together to create smaller offspring.

The majority of breeders will select the “runt,” or smallest size puppy from the litter to continue producing puppies of smaller sizes.

However, it’s worth noting that this breeding practice can lead to potential health issues in Teacup Cavapoos, as it may increase the likelihood of certain genetic health problems.

It’s important to research the breeder thoroughly if you are considering getting a Teacup Cavapoo, as some breeders may prioritize size over the health and well-being of the dog.

Additionally, you need to be aware that Teacup Cavapoos may require special care, as they are more delicate than larger dogs.

For this reason, they are not suitable to families with very young children as they can be easily hurt and they can quickly break their bones.

Teacup-sized Cavapoos are a subject of considerable debate, therefore we normally do not suggest this size.

Producing these tiny Cavapoos comes at a price as this size Cavapoo experiences a lot more health problems than any of the other sizes.

Toy Cavapoo

Toy Cavapoos are a smaller size variation of the Cavapoo mix breed, and they are the smallest size category of Cavapoos that I recommend.

They weigh between 7 and 13 pounds and stand up to 12 inches tall at the shoulder.

Toy Cavapoos was developed by breeding the smallest Poodles (Toy Poodles) and Cavalier King Charles Spaniels together, resulting in smaller offspring.

This breeding practice was done to create a smaller companion dog that is easier to care for in smaller living spaces.

Toy Cavapoos are still relatively rare and may not be available from all breeders.

Breeding smaller dogs together can potentially lead to certain health issues in Toy Cavapoos, such as patellar luxation, heart problems, and dental issues.

As with Teacup Cavapoos, potential owners should research the breeder thoroughly and be aware of the potential health issues that Toy Cavapoos may be prone to.

Toy Cavapoos are a great option for those who are looking for a smaller companion dog that is still very active and playful.

They enjoy daily walks and playtime, and they are very social dogs that enjoy being around people.

Toy Cavapoos are low to non-shedding, and they require regular grooming to keep their coats healthy and free of tangles.

They are just a tad bit larger than their Teacup counterparts.

If you live in a smaller space, such as an apartment or condo, a Toy Cavapoo could be an excellent choice for you.

Toy Cavapoos are able to do well in homes with limited space, in contrast to other Doodle breeds, which generally require a larger area in which to move around and exercise.

Mini Cavapoo

This size is a medium-sized variation of the Cavapoo breed and the size most commonly found.

The Mini Cavapoo full grown size has a weight range of 13 to 15 pounds and a height range of 13 to 25 inches.

They are larger than Toy Cavapoos but smaller than Standard Cavapoos.

This size is produced by crossing a Cavalier King Charles Spaniel and a Miniature Poodle, and it is only slightly larger than the Toy Cavapoo size.

Mini Cavapoo pups are the most popular because they are neither too small nor too large.

They are neither overly large, like a Goldendoodle or Labradoodle, nor are they undersized.

Mini Cavapoos have a low to non-shedding coat that requires regular grooming to keep it healthy and free of tangles.

They should be brushed at least once a week and trimmed every 8 to 12 weeks.

Mini Cavapoos are also prone to dental issues, so it’s crucial to maintain regular teeth cleanings and provide them with dental chews and toys.

These dogs are active and require daily exercise, such as walks, playtime, and interactive toys, to keep their minds and bodies active.

Mini Cavapoos are known for their friendly, outgoing, and affectionate personalities.

They are great with children and other pets, making them an excellent choice for families.

These dogs are also very intelligent and easy to train, making them a great option for first-time dog owners.

Mini Cavapoos love to be around people and thrive on attention, so they don’t do well when left alone for long periods.

These dogs are very adaptable.

Whether you are in a home, an apartment, or a condo, they can thrive in any place.

Standard Cavapoo

Standard Cavapoos or Cuddle Cavapoos are the largest size variation of the popular Cavapoo breed.

They weigh up to 25 pounds and stand up to 15 inches tall at the shoulder.

Standard Cavapoos are a result of breeding larger Standard Poodles and Cavalier King Charles Spaniels together, producing larger offspring.

Standard Cavapoos have the same friendly and outgoing personalities as the other size variations of Cavapoos.

They are great with children and other pets and are easy to train.

Standard Cavapoos require regular exercise to maintain their health and happiness, and they enjoy daily walks, playtime, and interactive toys.

Below is a table showing a summary of the different sized Cavapoos.

Another fact to keep in consideration is the sex of your puppy.

Female dogs tend to end up smaller than male dogs.

My Take

Because Cavapoos are not purebred dogs, their height and weight can differ tremendously.

You will even find great differences between litter mates with most litters having one large puppy, one tiny puppy, and the rest being of average size.

I highly recommend avoiding the teacup version because of the higher risk health-wise and also because they are easily injured.

However, whatever size Cavapoo you do decide to add to your home, you will be getting a lovable, adorable, and inseparable partner for many years to come.
