When Do Cockapoos Stop Growing?

The cockapoo is a delightful dog, one that makes an ideal pet for a family. Before you buy any dog, you should research the breed carefully and learn everything about it. Of course, that’s what we’re here for!

One of the most important factors when choosing the type of dog you want is considering the size of the space you live in. A large breed in a very small apartment, for example, will not be comfortable for you or the dog. Being a smaller breed, the cockapoo suits most types of accommodation and will be happy in a family environment.

A question that potential cockapoo owners and all sensible dog owners often ask is when do Cockapoos stop growing? How big will it grow, and how long does it take to reach full grown cockapoo size? Let’s see if we can answer that question of when a cockapoo stops growing and perhaps a few other important points as we go along.

At what Age Do Cockapoos Stop Growing?

Contents and Quick Navigation

A Cockapoo will stop growing at about nine months of age. They may continue to grow out a bit more up until they are about 12 months of age. After that, they may fill out a bit more as their muscles grow.

How Big Does a Cockapoo Get?

To answer this question, it is important to know the type of cockapoo you are looking at. Didn’t you know there was more than one? Many people don’t, which is another important reason research is essential! Let’s look at a Cockapoo full grown.

It’s also essential to know where cockapoos are concerned, and there is no a standard size. With pedigree breeds, the dogs are bred to a standard – an agreed size that is the maximum for that breed – but a cockapoo is a mixed breed, so you can only rely on a guideline as to when your dog is a fully grown cockapoo.

What can help you is that there are four categories of cockapoo sizes: Standard, Miniature, Toy and Teacup – listed there in descending order. All cockapoos are bred from a poodle and a cocker spaniel parent, yet both breeds also have various sizes. Poodles come in Standard, Miniature and Toy sizes, while Cocker Spaniels also come in large and small sizes.

You can see, then, that the parent dogs will affect the size of the puppies! Below is a general list as to the cockapoo size, but be aware it is just a general guide to a full grown cockapoo:

Standard – grows to between 15” to 18” at the shoulders, weight of up to 19lbs

Miniature – up to between 11” and 14”, and weighing between 13lbs to 18lbs

Toy – height between 9” and 10”, weight of maximum 12lbs

Teacup – the height of under 10” and less than 6lb in weight.

These figures – all averages – should give you a good idea of the type of dog that would suit you best. Teacup cockapoos are usually bought as lapdogs – as are the toy dogs – yet they still need plenty of exercise. The miniature and standard cockapoo is an energetic animal and, as we have talked about elsewhere, needs a good deal of outdoor exercise regularly.

The image above shows a cockapoo full grown on the left and a younger puppy on the right.

It is not common to see a teacup cockapoo in the UK – they tend to be more popular in the USA – so you are most likely looking at one of the other sizes. To sum up this section, you need to consider the size of your living area and how you will spend time with the dog, and always find a reputable breeder and talk to them in advance about the best dog for you.

How Fast Does a Cockapoo Grow?

If you are set on bringing a cockapoo, you will have already investigated the breed to learn as much as you can, and we have talked above about how large your dog will grow. Now let’s talk about how quickly that little ball of fun you take home from the reputable breeder will grow into an adult dog!

The truth is that smaller dogs take less time to reach their full cockapoo size. That’s because there is a lot less growing to do than for larger dogs! The problem with the cockapoo is, as with the size above, there is no standard as it is a mixed-breed dog.

The time it will take to reach maturity – the point at which it will grow no further – is therefore influenced by the parent dog. If you are sensible, you will have chosen a dealer and asked to visit. There, you will get to meet the parent dogs, so you will know the breed that your cockapoo puppy will be influenced by.

So, although there is no set standard – in other words, we cannot say how long your dog will take to grow to full grown cockapoo size – a helpful average is that a standard cockapoo bred from a standard poodle parent will reach maturity in around 9 months.

That’s not a long time. Of course, you will not notice it until one day, and you suddenly realise that the tiny puppy you once handled is now a full grown cockapoo, demanding playtime every hour of the day!

Conclusion of Cockapoo Size

Being a mixed breed, even the most reliable and reputable breeders cannot guarantee the cockapoo size of the puppies in the litter. You may find you have a small standard cockapoo, a large one, or a small or large miniature. The breeder will do their best, given past litters, so you will know when cockapoos stop growing.

By the way, make sure you choose a breeder that is approved by and registered with the Cockapoo Club of Great Britain (CCGB) – there’s a full list (as at the time of writing) of registered breeders here – as that will ensure you are dealing with the right people.

If you talk to a few breeders in advance of making a decision you may find that one has the perfect parent dogs for your preferred cockapoo size, so we advise you to visit the list, find those that are within travelling distance, and get in touch right away.

Remember, you are investing in a cockapoo that is not just a pet but will become part of the family, so prepare for many years of fun and enjoyment!
