When Do Cockapoos Stop Growing? [Cockapoo Full Grown]

Cockapoos are the delightful, loving, and energetic cross between Cocker Spaniels and Poodles.

Sometimes, with dogs that are crossbred rather than purebred, it may be difficult to predict certain physical and personality traits, including how big they will be when they finally stop growing.

If you’re thinking about adding a Cockapoo to your family, or you already have one and are desperately hoping they won’t grow out of their collar again, you have come to the right place! This article will teach you everything you need to know about the growth and development of Cockapoos, from birth and puppyhood through their adult lives. 

I will cover growth charts for Standard Cockapoos, as well as other variations, so you can have the most accurate idea of what to expect from your furry friend.

When Is A Cockapoo Fully Grown? The Basics

There are many factors that determine when your Cockapoo will be fully grown, the most notable of these being their parentage and genetics. If you know the relative size of both the mother and father, it will be easier to predict the final weight of their offspring. This method is not without room for error, though.

Generally speaking, Cockapoos reach their full-grown size and weight when they are two years old. However, the majority of their physical growth will take place in the first year of their life. Like all dog breeds, Cockapoos grow the most rapidly when they are very young, and as they age, their rate of growth begins to slow until they reach their end weight at around 24 months.

Three Varieties of Cockapoos And Their Sizes

There are three main varieties of Cockapoo that I will cover in detail. The variety is determined by the type of Poodle used to breed the puppies – Standard Poodles, Miniature Poodles, and Toy Poodles will each produce different results. 

Standard Cockapoo

Standard Cockapoos are the most common variety of Cockapoos you will encounter. They are also the largest, as they are bred with a Cocker Spaniel parent and a Standard Poodle parent. While Cocker Spaniels typically only weigh around 30 pounds, an adult Poodle may weigh at least twice the size of the smaller dogs.

The Standard Poodle parent has a significant effect on the ultimate size of their Cockapoo offspring. Standard Cockapoos usually grow between 18 and 20 inches tall. They may end up weighing 20 pounds or more.

Miniature Cockapoo

A Miniature Cockapoo is a highly sought-after cross between a Miniature Poodle and a Cocker Spaniel. They are slightly smaller than a Standard Cockapoo and usually weigh about 15 pounds when they are fully grown.

Teacup Cockapoo

As you may be able to guess from their name, Teacup Cockapoos are the smallest variety of Cockapoos that breeders make available. They are bred from a Cocker Spaniel and a Toy Poodle. Toy Poodles usually weigh between 4 and 6 pounds.

Thus, a Teacup Cockapoo will weigh roughly 5 pounds.

They are tiny, adorable dogs that can fit easily into a backpack or purse to go anywhere with you, hence their diminutive name. Because they are so small, Teacup Cockapoos grow at a slower rate than the other varieties of the breed. They also most often are done growing sooner – they generally reach their adult weight and height at around six months of age.

Frequently Asked Questions

In this section, we will go over the answers to some of the most frequently asked questions about the size and growth rate of the famous Cockapoo! 

How can I tell if my Cockapoo is overweight?

If your dog is excessively obese, you will be able to visually see the excess fat on their bodies. If it is difficult to discern visually, you can tell by feel. Run your hands along the sides of your dog’s body.

In a healthy dog, you will be able to feel some of its ribs. If your dog is overweight, you will not feel any protrusions.

It can be tempting to indulge your dog in treats every time they beg with their puppy dog eyes! However, ensuring they maintain a healthy weight is crucial to their long-term health and lifespan. Be sure to give your dog treats in moderation, and ensure that they get enough daily exercise to keep them fit and at a healthy weight for their breed.

Can I predict the adult size of my Cockapoo puppy by the size of its paws?

Generally speaking, it is a myth that you can tell how big an adult dog will be based on the size of a puppy’s paws. As the saying goes, the larger the puppy’s feet, the larger dog it will grow into.

But don’t fret! There is a more accurate and scientifically based method of determining how big your puppy will become. All it takes is knowing the birthday of your puppy, their current weight, and some simple multiplication.

Your Cavapoo puppy reaching the 12-week age milestone is the ideal time to try to guess their final size. Simply take their weight at 12 weeks and double it to end up with a rough estimation of what their weight will be after two years.

If you miss the 12-week milestone, you can perform a similar calculation when your puppy reaches 24 weeks. By multiplying their 24-week weight by 1.25, you will get an idea of how much they will weigh as an adult.

Keep in mind that these predictions are not guaranteed to be one hundred percent accurate. They are simply there as tools to help you get a ballpark estimate of how big your dog will be!

Do Cockapoos grow faster than other dogs?

How fast a dog grows is primarily dependent on the breed and parentage. Because Cockapoos are bred to be small to average-sized dogs, they will grow and develop quicker than larger breeds such as Retrievers, Dalmatians, and Great Danes. Logically speaking, these more giant breeds have a lot more growing to do, so naturally, it will take them more time.

What is the life expectancy of a Cockapoo?

So long as they have a healthy diet with regular exercise, Cockapoos can live long and happy lives. They are known to live around 13 years, with the oldest Cockapoos being closer to 20!

Because they are a cross between a Cocker Spaniel and a Poodle, they are genetically healthier than purebred dogs and, thus, are less likely to suffer from hereditary conditions that may limit the lifespan of otherwise healthy dogs and pups.

Final Thoughts

There you have it! Knowing when your Cockapoo will stop growing may not be an exact science with precise answers, but with these tools, you will have a great shot at predicting how tall and heavy they will be as an adult as well as how long they will take to reach this size.
