The Cavapoo, which some people know as Cavoodle or Cavadoodle, is an adorable hybrid dog that’s half Poodle and half Cavalier King Charles Spaniel. Since the Cavapoos origin in the 1990s, they’ve been popular and well-received in the dog world.
What makes them so special? They inherit their intelligence, trainability, and loyalty from the Poodle and their playfulness and gentle temperament from the Cavalier King Charles Spaniel.
Cavapoos are generally a small dog breed, but their size can vary. When getting a puppy, size is often a concern, especially for those living in small apartments or homes with small yards.
Families that are getting a dog for their young children want a dog the child can walk rather than the dog walking the child. While some people like big dogs, others prefer smaller dogs.
Just how big will my Cavapoo get when it’s fully grown?
This is one of the most frequently asked questions by potential Cavapoo owners. On Average, Cavapoos are 9” to 14” and weigh between 12 and 25 pounds when fully grown.
Although Cavalier King Charles Spaniels and Poodles are both small dogs, the size of the Cavapoo will depend a lot on what type of Poodle is used. Cavapoos can have either a Toy Poodle or a Miniature Poodle as the parent.
The size and type of Poodle is the biggest factor in how big the Cavapoo will be when it’s fully-grown.
How Big Will a Cavapoo Get?
Cavapoo breeders can’t determine down to the pound or inch how big a Cavapoo will get, but experienced breeders can make a fairly close estimate based on the parents. As mentioned, the type of Poodle plays a good part in size.
- Miniature Poodles can grow to be 10” to 15” tall and can weigh from 10 to 15 pounds.
- Toy Poodles are not usually taller than 10” and usually weight about 4 to 6 pounds.
- Cavalier King Charles Spaniels grow to be about 12” to 13” at the shoulder and weigh between 13 and 18 pounds.
Based on these weight and height averages, experienced breeders can often guesstimate what their litter will be as far as size.
As a rule, Cavapoos are generally 9” to 14” and weigh between 12 and 25 pounds. Like people, the Cavapoos weight and height can also vary because every dog is different.
Most litters have a big puppy, some average-sized puppies and a “runt of the litter”. However, the type and size of Poodle used in breeding is generally the biggest factor in how big the Cavapoo will be as an adult.
What Age Are They Fully Grown?
The puppy stage is a stage most dog owners enjoy when they first bring their little bundle of playfulness home. However, it’s also a stage that owners often wish would be done much quicker than it is.
This is because the puppy stage usually involves chewing on things, having accidents in the house and just plain getting into mischief.
New dog owners are often surprised to hear that some puppies are still puppies and not fully grown until they’re between one and two years old. Why the variance between one year and two years?
This is because the age at which a dog is full-grown usually depends on the dog or, more importantly, the breed of the dog.
The age at which a Cavapoo is fully-grown may not necessarily be the age at which they’re considered adult dogs either because they all mature at a different age.
Toy dogs are usually fully grown by the age of 8 months while a giant breed dog is not full grown until it’s almost two years old. Small breed dogs like Cavapoos are usually fully grown by the time they’re one year old.
Despite Cavapoos possibly coming from a toy or a miniature Poodles, they’re classified as small breed dog dogs. Therefore, Cavapoos usually reach their adult size of 12-25 pounds at about one year of age.
Are There Different Sizes?
Yes, there can be a variety of different sizes just in one litter alone. As with any dog breed, there are going to be different sizes. Using the Cavalier King Charles Spaniel as an example, this dog has a size range of 13 to 18 pounds and 12 to 13 inches tall.
Then you add the Poodle to the mix, which can be from 4 pounds to 15 pounds depending on if a Toy or Miniature Poodle was used in the breeding.
Mixing a toy Poodle with the Cavalier King Charles Spaniel, you’re dealing with one dog that might weigh only 4 pounds a mate that might weight 13 pounds, or you can have a 15-pound miniature Poodle mating with an 18 pound Cavalier King Charles Spaniel.
You can see that this could result in litters of varying sizes. While they may look similar at birth, they probably won’t be similar when they’re adult dogs.
How Long is a Cavapoo a Puppy?
Cavapoos are such playful and often mischievous puppies that owners might be tempted to say they’re puppies for far too long!
The puppy stage actually consists of three parts, and the Cavapoo puppy must complete all three development stages before he is truly an adult dog.
- Mental maturity
- Physical maturity
- Sexual maturity
Unfortunately, these three stages are not completed at the same time or at the same rate. Small breed dogs may reach physical maturity (size) at as young as 8 months, they are not sexually or mentally mature.
It’s just that they’ve reached their adult size in weight and height. In some cases, they might even grow a little more between the age of 8 months and one year. Each dog is different.
The Cavapoo may also reach sexual maturity before it reaches physical or mental maturity. If a dog is not sterilized, and the owner is not diligent and careful, the dog can become pregnant as young as six months of age.
At this age, the dog may be sexually mature in that she can give birth, but she’s not physically or mentally mature.
Small breed dogs like Cavapoos generally are no longer a puppy by the time they’re 18 months old, but this can vary a few months either way.
Do Cavapoos Experience Any Growth Spurts?
From the time you get your Cavapoo, it will seem like he’s constantly experiencing growth spurts. When you first bring your Cavapoo home, he’ll probably only be about 8 weeks old and will resemble a hundred other puppy breeds.
After all, haven’t you heard that all puppies look alike? They actually don’t all look the same, but they often look so similar that it may be hard to determine their breed.
By the time the Cavapoo puppy reaches the age 12 to 16 months, he’ll lose a lot of his puppy appearance, and will begin to look more like a Cavapoo.
During this stage, it will seem like all he does is eat, and you’ll notice a weight gain and a real growth spurt. From four to six months of age is when your Cavapoo will gain the bulk of his weight.
By the time the Cavapoo is six months old, he’ll probably be 75% of his full adult weight if not his full adult weight.
Keep in mind that these are the growth rates of most Cavapoo dogs and similar small breed dogs, but every dog grows at a certain rate. Certain factors can also affect a dog’s growth, including exercise, food consumption, type of dog food and health.
When Cavapoo puppies go through certain growth spurts, they also go through behavioral changes depending on the age. Below is a rundown of the different growth stages of the Cavapoo puppy.
- Newborn and Neonatal Stage (birth to two weeks) – During this period, they’re blind, deaf and toothless. Staying fed and warm is their main concern. They will cry if their needs are unfulfilled.
- Transitional Stage (two to four weeks) – During this period, their eyes and ears are open, and they’re learning how to yelp and make bark-like sounds. They also experience a little independence from their mother.
- Socialization period (four to twelve weeks) – During this stage, the Cavapoo is not only learning about socialization but is also weaned and eating dog food, which plays a large part in the physical growth spurt at this age.
- Adolescence period (six to twelve months) – While the Cavapoo may still be sexually and mentally immature at times, they’ve usually reached their physical maturity as far as weight and height.
Social maturity generally is completed by the time the Cavapoo is two years old. At this time, he may seem like an old dog already despite having many good years left.
