What is a Cavapoo?

Cavapoos are a popular hybrid dog, created by breeding a Cavalier King Charles Spaniel with a Poodle. Cavapoos are known for being intelligent, friendly, and low-shedding, making them a great choice for allergy sufferers and families with young children.

These affectionate dogs come in a variety of colors, including black, white, brown, red, and mixed. Their coat ranges from gently curling to higher curls and are often described as “wooly”. They are relatively easy to train and make excellent companions.

Cavapoo Size Guide

Cavapoos can be categorized into Three Different Sizes: Teacup, Toy, and Miniature

Teacup Cavapoo

Teacup Cavapoos are the smallest of the Cavapoo bunch and are made usually produced by breeding an F1 Toy Cavapoo with a Teacup Poodle. Alternatively, a breeder will selectively breed the runts of the litter to get a smaller size.

Teacup Cavapoo size:

They are a similar height to a Chihuahua standing at around 6 to 8 inches tall and weigh a teeny tiny 5 to 9 pounds.

Be cautious of the teacup size. The American Kennel Club (AKC) does not recognize the Teacup Poodle as a purebred dog – mainly due to the many health issues they can get.

Many of these dogs are selectively bred by Cavapoo breeders for their pint-size rather than their overall health status. This can result in inherited health problems such as hydrocephaly, portosystemic shunts, and fragile bones.

Toy Cavapoo

If you want a lap dog then you may want to consider a Toy Cavapoo. These designer dogs are smaller than average and can be either:

  • An F1 (Cavalier King Charles Spaniel parent crossed with a Toy Poodle) or
  • F1b mixed breed (an F1 Cavapoo bred crossed with a Toy Poodle)

They are often a result of an F1 cross (that is, a Cavapoo bred with a Toy Poodle) as they are consistently small in size.

Toy Cavapoos are generally healthier than their Teacup cousins as their Toy Poodle parents are generally healthy dogs. This is due to the fact that Toy Poodles are recognized by the American Kennel Club which has strict breed guidelines.

Toy Cavapoo size:

They typically weigh between 7 and 13 pounds (3.2-6 kg) and stand between 8 and 12 inches (20-30 cm) tall at the shoulder.

Miniature Cavapoos (Cavapoos)

Next up in size is the Mini Cavapoo, which is the most common type of Cavapoo. They are small dogs that can be produced from the below crosses:

  • A First generation doodle from a Miniature Poodle crossed with a Cavalier King Charles Spaniel.
  • An F1b (first generation) doodle bred from a miniature Cavapoo and a Mini Poodle will give a more consistent small size.
  • An F2 (second generation) doodle bred from two miniature Cavapoos

Mini Cavapoo Size:

Miniature Cavapoos stand between 12-14 inches (30-36 cm) at the shoulder and weigh in between 13-18 pounds (6-8kg).

What About Standard Cavapoos?

Cavalier King Charles Spaniels are not typically bred with Standard Poodles so you will not come across a Standard Cavapoo very often.

What is the average Cavapoo size and how much do they weigh?

Cavapoos are smaller dogs. The average Cavapoo size is between 10 and 18 pounds and is classed as a small dog breed

When is a Cavapoo Fully Grown?

Cavapoos reach their full adult size at approximately 12 months of age give or take two weeks on either side. Teacup and Toy Cavapoos can reach their adult size slightly earlier at 10-11 months old.

How big are Cavapoo Puppies when you take them home?

When you first bring your Cavapoo puppy home they will be between 8 and 12 weeks old. You can expect these precious pint-sized pooches to be about 8-10 inches (20-25 cm) tall and 2-5 pounds (0.9-2.3 kg). They will likely be able to sit on the palm of your hand.

Of course, there is some variation among individual dogs, so your pup may be slightly larger or smaller than this. However, this is a good general range to expect.

How Much Growth Can You Expect During the First Year?

During their first year of life, Cavapoos can experience several growth spurts. They will typically gain about 5-10 inches (12.7-25.4 cm) in height and double their weight. Of course, there is some variation among individual dogs, so your pup may grow slightly more or less than this. However, this is a good general range to expect.

Miniature adult Cavapoos will reach their full height at 12 months of age. Toy and Teacups can reach there full height slightly more quickly at 10-11 months of age

When Do Cavapoos reach sexual maturity?

Cavapoos reach sexual maturity at around 8-12 months of age. This is when they are able to have puppies or sire puppies of their own. However, it is strongly recommended not to allow your female dog to become pregnant until she is completely mature at 18 months of age.


How can I predict my Cavapoo’s adult size?

The full size of a Cavapoo can be estimated by doubling its size at 4-5 months old. If a Mini Cavapoo weighs 6 pounds at 4-5 months, it will weigh 12 pounds when it is fully grown.

Toy and Teacup Cavapoos can reach their adult size sooner at 10 or 11 months. You can weigh them at 4 months and double their pounds to determine their adult weight.

Factors that can affect the size of the Cavapoo


Cavapoos are generally small dogs with big hearts. The type of poodle the Cavalier King Charles Spaniel is crossed with is the biggest factor in how big the offspring will be.

If you want a larger dog, make sure to pick a larger parent breed. The biggest cross will be from a Standard Poodle Parent bred with a Cavalier King Charles Spaniel.

Genetics as A Factor of Size Variation:

There is a lot of variation among Cavapoos in terms of size. This is due to the fact that there are many different ways to crossbreed Cavaliers and Poodles.


Male for Female? – Male Cavapoos tend to be slightly larger than females by a couple of pounds and an inch or so, so this is something to keep in mind if the size is a priority for you.

Gender as A Factor of Size Variation:

As we all know, males are generally larger than females. The average male Cavapoo weighs between 11 and 18 pounds (5 and 7.5 kg) and the female Cavapoo weighs between 10 and 16 pounds (4.5 and 7 kg).


A healthy diet is essential for all dogs, but it can be especially helpful in promoting growth for puppies. Make sure your pup is getting enough calories and nutrients to support their growth.

Cavapoo Health And Diseases

Cavapoos are generally a healthy breed of dog, but like all designer breeds, they can be susceptible to certain health conditions. Some of the most common health problems seen in this gorgeous popular dog include hip dysplasia, patellar luxation, epilepsy, and heart disease. A reputable breeder should be able to screen for many of these diseases in the parents so it is really important to do your research.

1. Hip Dysplasia:

Hip dysplasia is a condition that can affect the hip joints of dogs. It occurs when the hip joint does not develop properly, which can lead to pain and lameness. Cavapoos are particularly susceptible to this condition, so it’s important to have your pup checked by a veterinarian if you notice any signs of hip problems.

2. Patellar Luxation:

Patellar luxation is a condition that affects the kneecap. It occurs when the kneecap is dislocated from its proper position. This can cause pain and lameness. Cavapoos are particularly susceptible to this condition, so it’s important to have your pup checked by a veterinarian if you notice any signs of knee problems.

3. Heart Disease

Cavalier King Charles Spaniels are prone to developing a heart condition called mitral valve disease. This condition can lead to heart failure and death. Cavapoos are also at risk for this condition, so it’s important to have your pup checked by a veterinarian if you notice any signs of heart problems.

4. Epilepsy

Epilepsy is a neurological condition that can cause seizures. Cavapoos are particularly susceptible to this condition from their Poodle parents, so it’s important to watch out for any unusual signs in your dog such as staring off into space and not responding and seizures.

5. Other Health Problems:

Other health issues that can affect Cavapoos include allergies, ear infections, liver disease, eye disorders such as progressive retinal atrophy (PRA), and other conditions. If you detect any of these or other health concerns, it is critical that your dog be examined by a veterinarian.

Is there a size of Cavapoo that is more prone to health issues?

Yes – the teacup Cavapoo is more prone to health issues such as hypoglycemia, hydrocephaly, liver shunts, and luxating patella. They are also more prone to injury due to their small size.
