How Big Does a Cavapoo Get? Size & Weight Guide (With Chart)

Jessica Kim

By Jessica Kim


Cavapoos are growing increasingly popular because of their friendly temperaments and low-shedding coats. While most Cavapoos tend to stay on the smaller side, some can grow to become medium-sized dogs. This is because Cavapoos are a hybrid of the Cavalier King Charles Spaniel and the Poodle. Poodles come in three sizes, and while most Cavapoos have Toy or Miniature Poodle parents, any type of Poodle can breed with a Cavalier King Charles Spaniel. You can expect a Toy Cavapoo to grow to 9–12 inches and weigh between 7–13 pounds. A Miniature Cavapoo usually grows to 12–16 inches tall and weighs between 12–25 pounds.

It’s important to have general knowledge of a Cavapoo’s growth and development because it can help you determine if your puppy is experiencing healthy growth. Here’s what you can anticipate during the growth and development stage of a Cavapoo puppy.


Cavapoo Breed Overview

The Cavapoo is a hybrid dog breed that first started appearing in the 1950s. These dogs were originally bred as companion dogs with allergy sufferers in mind. Breeders had hoped to breed dogs that had the friendly and affectionate nature of Cavalier King Charles Spaniels and the intelligence and low-shedding coat of Poodles. Despite their popularity, Cavapoos aren’t recognized as an official and distinct dog breed. However, it’s usually not that difficult to find a Cavapoo dog breeder.

In general, Cavapoos are great dogs for first-time dog owners and families with children. They love being around people and are usually good playmates for children. They’re also intelligent and eager to please, so most people have a relatively easy time training them.

It’s important to keep in mind that Cavapoos are companion dogs, and they do not do well being left home alone for long hours. They’d love nothing more than to spend all day with their favorite people. They’re usually energetic, easygoing, and relatively small, so it’s easy to take them with you to many different places.

Cavapoo Size and Growth Chart

Compared to purebred dogs, Cavapoos have greater variances in their sizes and weight. Most Cavapoos won’t weigh more than 20 pounds when they reach adulthood, but perfectly healthy Cavapoos can be much smaller or larger than this average. Since there can be such differences in sizes, it’s important to track your Cavapoo’s growth with your veterinarian. This will ensure that they’re getting all the nutrients they need for healthy growth and development. Here’s a chart that lays out the general growth track of most Cavapoo puppies.

Age Weight Range Height Range
1 month 3–4 lbs. 4–5 in.
3 months 5–7 lbs. 4–6 in.
6 months 8–10 lbs. 6–10 in
10 months 10–14 lbs. 7–12 in.
12 months 10–17 lbs. 9–15 in.
14 months 10–23 lbs. 9–17 in.

When Does a Cavapoo Stop Growing?

Most Cavapoos will reach their full size when they’re about 12 months old. Larger Cavapoos that have Miniature Poodle parents may take a little longer to grow to mature adults and can keep growing until they’re about 13 months old. Smaller Cavapoos that have Toy Poodle parents may mature a little faster and stop growing at 11 months old.

Cavapoos will experience the most growth when they’re between 4 and 7 months old. Then, their growth will start to slow down and taper off until they reach full maturity at about 12 months old.

Factors Affecting the Size of Cavapoos

Many different factors will affect the size of a Cavapoo. First, it’s important to consider genetics. While a Cavapoo will not always grow to the same size as their parents, looking at their lineage can be a good way to predict your Cavapoo’s size. Most Cavapoos have either a Toy Poodle or Miniature Poodle parent and are differentiated as Toy Cavapoos and Miniature Cavapoos.

Cavapoos are also categorized by their generations. The first generation of Cavapoos, also known as F1 Cavapoos, Have one Cavalier King Charles Spaniel parent and one Poodle parent. F1B Cavapoos have one Cavapoo parent and one Poodle parent. An F1BB Cavapoo has an F1B Cavapoo parent and a Poodle parent. A Cavapoo that has two Cavapoo parents is also known as an F2 Cavapoo.

Breeders can produce litters of Cavapoo puppies with more consistent sizes when they breed two Cavapoos. F1 Cavapoos tend to have the most variances in sizes, coat types, and appearances.

Environmental factors also affect a Cavapoo’s growth. Diet and exercise play a role in growth and development. So, it’s important to feed your Cavapoo a healthy diet in the correct proportions to prevent malnourishment or excessive weight gain. Cavapoos also need plenty of exercise opportunities to promote healthy bone, joint, and muscle development.

Ideal Diet for Maintaining a Healthy Weight

In general, puppies require a special diet that’s very different from an adult dog’s diet because they have different nutritional needs. So, make sure to feed your Cavapoo puppy dog food with a puppy formula. Since Cavapoos tend to be small dogs, it’s beneficial to look for a formula that’s specifically made for small dogs. This is because small dog breeds and large dog breeds have different nutritional requirements and mature at varying rates. Smaller dogs are also more susceptible to getting low blood sugar or becoming hypoglycemic.

For the most part, puppies don’t require any additional supplements as long as they’re eating high-quality puppy food. They should continue eating puppy food until they’re about 12 months old. Then, you can start to transition them to food with adult dog formulas.

How to Measure Your Cavapoo

All you need to measure your Cavapoo’s growth are a tape measure, a pet scale, and a growth chart to record your Cavapoo’s measurements. It’s also helpful to have treats to keep your Cavapoo still as you take their measurements. You can train your Cavapoo to sit when they’re on the scale so that you get accurate readings.

When it comes to measuring your Cavapoo’s height, start at their shoulder blade and measure to the base of their front paw. Make sure to measure your Cavapoo while they’re standing as there’s a height difference between a sitting and standing dog.

Overall, there are significant variances in Cavapoos’ heights and weights because of different factors. For the most part, you can expect a Toy Cavapoo to grow to 9–12 inches and weigh between 7–13 pounds. A Miniature Cavapoo usually grows to 12–16 inches tall and weighs between 12–25 pounds.

Giving your Cavapoo puppy a proper puppy diet and plenty of exercise will greatly reduce the risk of malnourishment and insufficient growth and development. Staying on top of vet appointments will also help ensure your Cavapoo’s on a healthy growth track and give them a strong start to living a happy and healthy life.
