The Size of a Cavapoos Parents Influence Their Size

When determining the size of a Cavapoo, it’s worth noting that as this breed is classified as a crossbreed, there are no formal standards. But we can take the size guide from the parents who are the Cavalier King Charles Spaniel and the Poodle.

The height is taken from a standing position from the ground to shoulder height. So you can expect an additional few inches for head height.

The Cavalier King Charles Spaniel has an average height of 12-13 inches (30-33cm). And they weigh in at 13-18 pounds (6-8 kg).

The Cavapoo size is further influenced by the size of the Poodle who will be either a toy Poodle or a mini Poodle.

Toy Poodles are 10-11 inches (25-28 cm) in height. And they weigh 6-10 pounds (3-4.5 kg).

Miniature Poodles are 11-15 inches (28-38 cm) in height. And they weigh 26-30 pounds (12-14 kg).

The cross between the Cavalier Kings Charles and Poodle will produce Cavapoos with the following heights and weights.

Toy Cavapoo Size

The size of a Toy Cavapoo is on average 9-11 inches (24-30 cm) in height and up to 11 pounds (5kg) in weight.

Due to their height and weight, toy Cavapoos are known as small-sized dogs.

A few benefits of a toy Cavapoo over a mini Cavapoo listed by Cavapoo owners include:

  • Due to their smaller size, toy Cavapoos are easy to take anywhere.
  • A toy Cavapoo is lightweight and can be lifted up without too much effort.
  • The grooming costs could be cheaper for a toy Cavapoo compared to a mini Cavapoo.

Miniature Cavapoo Size

The size of a miniature or mini Cavapoo is on average 12 -15 inches (30-38 cm) in height and 11-20 pounds (5-9 kg) in weight.

Due to their height and weight, mini Cavapoos are known as medium-sized dogs.

A couple of benefits of a mini Cavapoo over a toy Cavapoo by Cavapoo owners include:

  • Mini Cavapoos may enjoy longer walks due to their medium size.
  • The larger size of a mini Cavapoo is attractive for owners looking for a larger-sized dog.

Factors That Influence the Size of a Cavapoo

Cavapoo Puppy - How Big Will My Cavapoo Grow

Ultimately, both toy and mini Cavapoos can vary in size from their predicted advertised height and weight.

Many Cavapoo owners say their new pup was supposed to be a toy and ended up much larger. And vice versa; their mini Cavapoo was much smaller in size than expected. In either case, you will no doubt love your bundle of fur no matter its size.

Speaking directly with a reputable breeder and confirming the breed line will help to give a more accurate indicator of the size of your Cavapoo.

There are also a number of other factors that can influence how big your Cavapoo will grow. They include the following:

Cavapoo Gender

The gender of the Cavapoo can influence its size.

Female Cavapoos are on average 10% smaller than male Cavapoos.

Although this is a small number, it’s worth noting because a mini Cavapoo male could be a good inch or two bigger than a female Cavapoo born in the same litter and weigh proportionally more.

As you can see from the above image, our Coco, a female black mini Cavapoo weighs only 11 pounds (5kg) which is more in line with what you would expect a toy Cavapoo to grow. She was also the smallest of her litter (the runt) which can also contribute to a smaller size – but certainly not always!

Cavapoo Generation

The generation of Cavapoo can influence their size.

A first-generation Cavapoo, also known as an F1 Cavapoo is a mix of a purebred Cavalier King Charles Spaniel and a purebred Poodle.  

However, when the generations start to mix further, and the genetic makeup is altered to reflect a taller parent, for example, the mini Poodle, then in theory the offspring will be taller and potentially weigh more.

Cavapoo Parents Size

As we have seen, the height and weight of the Cavapoo’s purebred parents can vary. And this will influence the size of the resulting litter.

So if a purebred Cavalier is on the small side, bred with a smaller-sized mini Poodle, then the resulting litter might reasonably produce smaller Cavapoos.

However, while the genetics of the parents do not always correspond in this way, just like in humans and other animals, it does give us a good indicator of what to expect from the offspring.

Food and Exercise

Although the amount your Cavapoo eats and the exercise he has won’t generally affect his height, it can of course affect his weight.

Cavapoos are small breed dogs so it is important to be mindful of additional treats. They can quickly add up to unnecessary pounds and poor health.

Instead, stick to the recommended daily food intake for your Cavapoo to keep him in top condition.

Additionally, Cavapoos benefit from regular moderate exercise. A 30-45 minute walk each day is usually the perfect amount of exercise for your healthy adult Cavapoo.

Some larger-sized Cavapoos might enjoy longer walks while smaller toy Cavapoos might even struggle with 30 minutes.

Exercise can also depend on whether you have a toy or mini Cavapoo. And sometimes it just comes down to personality. Where some dogs love a walk others will tire easily.

Some owners of toy Cavapoos say their pooch is not interested in walks. Instead, they prefer a good play session or time exploring in the yard. And depending on their size, this may be enough exercise for them.

What About a Standard and Teacup Cavapoo?

You may have come across the term ‘standard’ Cavapoo. This can be in reference to meaning either the mini Cavapoo, as this is generally the most popular size for this dog.

It can also mean that one of the parents is a standard-sized Poodle. However, generally, standard Poodles are not used to produce Cavapoos, instead, miniature and toy Poodles are the preference.

The Teacup Cavapoo is the result of selectively breeding smaller and smaller dogs in order to produce a tiny pup. This can be achieved by breeders who choose the smallest of a litter, also known as the runt, and breed with another smaller-sized dog.

The result of this breeding may be an even smaller dog still. But along with the tiny size, there are a host of health problems associated with breeding dogs so small.

We recommend sticking with the already cute and cuddly perfection of the mini and toy Cavapoos.

When is a Cavapoo Fully Grown?

How Big Will My Cavapoo Grow - Sizes Explained (Cavoodle)

As a small breed, Cavapoo dogs are usually fully grown by 12 months of age.

Generally the smaller the breed of dog, the faster they grow to their adult size.

So a toy-sized dog can reach their fully grown size by as early as 8 months. While a large breed dog will reach their fully grown size by 18 months to 2 years.

Cavapoos can have their most noticeable growth spurt when they are 3-6 months old. You may notice your puppy really growing bigger at this stage.

When your Cavapoo puppy is 6 months she might already be 3/4 of her adult weight.

After this time, growth may slow down. And then by around 12 months, she will have reached her adult size and weight.

Cavapoo Growth Milestones

The growth of your Cavapoo puppy includes three key stages. They are her physical maturity, her mental maturity, and sexual maturity.

These growth milestones don’t necessarily happen simultaneously. But do generally occur over the first 12 months of her life. 

In the case of a female Cavapoo puppy, it’s important to be aware that she could become fertile as young as 6 months. While she might be capable of producing a litter of puppies, it’s important to know she is not physically and mentally mature yet.

Generally, by the time your Cavapoo is 12 months old, she will be fully grown, give or take a few months.

Final Thoughts

If you would prefer a smaller-sized dog, then a toy Cavapoo would be ideal. On the other hand, if you would love to welcome a medium-sized dog into your life then a mini Cavapoo would be perfect. Whatever you decide, I hope this article is helpful in identifying the right-sized Cavapoo for you and your family.
