How Big Do Cavapoo Dogs Get?

When adding a Cavapoo to your family, one of the most common questions is, “How big do Cavapoos get?” Their size can vary depending on the genetics inherited from their parents: the Cavalier King Charles Spaniel and the Poodle.

Whether you’re looking for a compact lap dog or a slightly larger companion, understanding the factors that influence Cavapoo size can help you prepare for your new furry friend. 

In this guide, we’ll explore the typical sizes of Cavapoos, the factors that influence their growth, and tips for managing their development. 

 The Size Categories of Cavapoos 

How big do Cavapoos full grown get? This small breed typically weighs 8–25 pounds and stands 9–14 inches tall. Their size can vary depending on whether the Poodle parent is a Miniature or Toy Poodle. Cavapoo dogs are generally divided into two main size categories based on the size of their Poodle parent.

 1. Toy Cavapoos 

•   Height: 9-12 inches at the shoulder 
•   Weight: 7-15 pounds 

These are the smallest Cavapoos full grown, bred from a Cavalier King Charles Spaniel and a Toy Poodle. Their petite size makes them perfect for apartment living or families seeking a small dog that’s easy to carry and snuggle.  You can read more about toy cavapoo sizes here https://storytaildogs.com/2025/04/03/toy-cavapoo-guide/

2. Miniature Cavapoos 

•  Height: 12-16 inches at the shoulder 
• Weight: 15-25 pounds 

  Slightly larger than Toy Cavapoos, Miniature Cavapoo dogs are ideal for families who want a playful companion that isn’t too small. With their sturdy build, they’re great for active households with children or other pets. 

While less common, some breeders may use a Standard Poodle to create a larger Cavapoo. These dogs can exceed 25 pounds, though they’re still relatively small compared to many other breeds. 

 

What Influences Cavapoo Size? 

Several factors contribute to the size of a Cavapoo dog full grown. While there’s some predictability, it’s important to remember that every Cavapoo is unique: 

 1. Parent Genetics 

The size of the Poodle parent is the most significant determinant of a Cavapoo’s size. Toy Poodles produce smaller Cavapoos, while Miniature Poodles result in larger ones. Cavalier King Charles Spaniels are small dogs, typically weighing 13-18 pounds, which helps keep Cavapoos moderate in size. 

 2. Generation of the Cavapoo 

  First Generation (F1): These Cavapoos have one Cavalier and one Poodle parent, making their size more predictable. 

  Second Generation (F1b, F2): These may have varying size traits depending on the parents used in breeding. 

 3. Nutrition and Health 

A Cavapoo’s growth depends on a balanced diet and regular exercise. Puppies fed high quality food designed for their growth stage are more likely to reach their full potential. Overfeeding or underfeeding can lead to size and health issues, so it’s essential to follow your veterinarian’s advice. 

 4. Exercise and Lifestyle 

Activity levels can also play a role in your Cavapoo puppy’s size. Regular exercise ensures healthy muscle development and prevents excessive weight gain, which can make a dog seem larger than their genetic potential. 

How Big are StoryTail Dogs Cavapoos?

At StoryTail Dogs, our Cavapoos are bred to be the perfect blend of size, charm, and adaptability. While their size can vary slightly depending on individual genetics, our Cavapoo puppies typically grow to around 12-14 inches tall at the shoulder and weigh approximately 14 pounds as adults. This moderate size makes them ideal companions for both cozy apartments and spacious homes. Their compact yet sturdy build ensures they’re small enough to snuggle on your lap but large enough to join in on family adventures. Whether you’re seeking a playful partner or a calm cuddle buddy, our Cavapoo dogs are the perfect size for any lifestyle!

 Cavapoo Puppy Growth Stages: What to Expect 

Cavapoo puppies typically reach their full height and weight by their first birthday. However, some may continue to fill out and develop muscle mass until they are 18 months old. Here’s a general timeline for their growth: 

•  0-6 Months: Rapid growth, especially in height. Puppies at this stage may seem lanky as they grow into their frame. 
•  6-12 Months: Growth slows, and weight gain becomes steadier as they approach their adult size. 
•  12-18 Months: Final growth stage, where muscle tone develops and their adult body shape solidifies. 

Growth charts can help you track your Cavapoo Puppies development. If you’re unsure about their progress, consult your vet for guidance. 

 Size Comparison with Similar Breeds 

Cavapoos often fall into the small dog category, but how do they stack up against similar breeds? Compared to Maltipoos, Cavapoos full grown tend to be slightly larger, often reaching around 12 14 inches in height and 14 pounds in weight. Cockapoos, on the other hand, are generally larger than Cavapoos, particularly when bred from standard sized Poodles. Mini Goldendoodles, while similar in temperament and appeal, are typically significantly larger, weighing 20 40 pounds. Cavapoos strike a perfect balance, offering a compact size that’s still sturdy enough for active play and family life. 

What are the best lifestyles for different Cavapoo sizes?

The Cavapoo’s size makes them ideal companions for a variety of lifestyles. Their small stature fits perfectly into apartment living, while their moderate energy levels make them great for families with children or older adults looking for a more relaxed pet. They are easy to transport, whether for a road trip, a flight, or a simple visit to the park. Their size also means they’re less intimidating for young kids and smaller pets, making them adaptable to multi pet households or quieter homes. 

 A Cavapoo dog’s size plays a crucial role in selecting the right accessories to keep them comfortable and secure.

Cavapoo Puppy Crate

When choosing a crate, you want to ensure it is appropriately sized to allow your Cavapoo dog to stand, turn, and lie down comfortably, without feeling too cramped. A small or medium-sized crate typically works well for Cavapoos, providing just enough space for them to feel cozy and safe while also making it easy to transport them. The crate should not be so large that they feel insecure, but also not too small to restrict movement.

Cavapoo Puppy Leash Reccomendations

For leashes, the size and weight are key considerations; lightweight, durable leashes with secure clips are the best choice for Cavapoos, ensuring they don’t feel weighed down or uncomfortable. This makes walks a pleasant experience for both the dog and the owner, without putting unnecessary strain on their small yet energetic frame.

Cavapoo Dog Beds

As for beds, Cavapoos full grown appreciate a soft yet supportive option that provides both comfort and proper orthopedic support, especially since they are small dogs with a lot of energy. A bed that is just the right size will give them a perfect spot to curl up and relax after a play session or a walk.

Whether you’re choosing a crate, leash, or bed, the manageable size of a Cavapoo makes it easier to find accessories that not only fit perfectly but also offer great affordability without compromising on quality. With the right selections, your Cavapoo will enjoy comfort and support throughout their daily activities.

 Cavapoo Training and Behavior Related to Size 

The Cavapoo’s small size brings unique considerations for training and behavior. While their petite build makes leash training less physically demanding, it’s important to ensure they don’t develop bad habits like pulling or jumping. On the bright side, their small size and eager to please personality make them quick learners during obedience training, provided positive reinforcement techniques are used.

 How to Choose the Right Cavapoo Size 

Choosing the right Cavapoo dog size comes down to matching their physical traits with your lifestyle. If you’re looking for a smaller dog that’s easy to carry and handle, a toy sized Cavapoo might be perfect. On the other hand, slightly larger Cavapoo puppies offer a bit more sturdiness for active households or families with younger children. Be sure to discuss size expectations with your breeder, as the size of the parents can give you a good idea of how large (or small) your Cavapoo will grow. Regardless of size, Cavapoos are known for their sweet and adaptable nature, making them a fantastic addition to any home.

 Preparing for Your Cavapoo’s Size 

Knowing your Cavapoo’s potential size helps you prepare for their arrival: 

•   Living Space: While both Toy and Miniature Cavapoos adapt well to various environments, smaller Cavapoos may thrive better in apartments, while larger ones enjoy homes with backyards. 
•   Supplies: Choose the right sized crate, bed, and harness. Too large, and they may feel insecure; too small, and they’ll be uncomfortable. 
•   Activity Level: Larger Cavapoos may have slightly higher energy needs, requiring more playtime and walks. 

 

The Joy of Cavapoo Companionship 

No matter their size, Cavapoos are beloved for their affectionate and playful personalities. Their intelligence makes them highly trainable, and their gentle nature means they’re wonderful with children, seniors, and even other pets. 

Understanding their size helps you ensure they’re comfortable, healthy, and happy in your home. Whether you choose a Toy or Miniature Cavapoo, one thing is certain: their heart will be much bigger than their physical size! 

The Cavapoo’s combination of size, temperament, and intelligence makes them an outstanding choice as emotional support animals or therapy dogs. Weighing around 14 pounds and standing 12-14 inches tall, Cavapoos strike the perfect balance between portability and sturdiness. They are small enough to accompany their owners on planes, public transportation, or visits to the doctor, yet their sturdy build allows them to keep up with an active lifestyle, whether it’s hiking, walking in the park, or playing with children. This versatility makes them highly adaptable to a wide range of situations and environments.  

Beyond their convenient size, Cavapoo puppies near me possess a naturally affectionate and intuitive nature. They form deep bonds with their human companions and seem to instinctively know when someone needs comfort or reassurance. Their calm demeanor and loving disposition help create a sense of security and emotional stability, qualities that are invaluable in emotional support and therapy roles. Cavapoos are particularly suited for individuals dealing with anxiety, depression, or trauma, as their gentle presence can provide a sense of grounding and peace.

Cavapoos’ intelligence and eagerness to please make them highly trainable, allowing them to learn the specific tasks or behaviors needed for their role. This includes everything from remaining calm in stressful environments to providing consistent companionship. Many Cavapoos have excelled as therapy dogs, visiting hospitals, nursing homes, and schools to bring comfort and happiness to those in need. Their ability to connect with both children and adults makes them a versatile choice for families, individuals, and professionals seeking an emotional support or therapy dog.

Ultimately, the Cavapoo’s compact size, warm temperament, and adaptability create a unique combination that makes them well suited to bringing joy and healing wherever they go.
