Cockapoo Full Grown Sizes: Standard, Mini, Toy & Teacup

The Cockapoo is a mixed breed that’s a cross between a Cocker Spaniel and a Poodle.

It is also known as the Cockerpoo, Spoodle, or Cockerdoodle.

As is the case with mixed breeds, the Cockapoo has no standard Kennel Club description as it has not been recognized by any major Kennel Clubs.

Thus, there is no uniform size and you can expect many variations depending on the parents crossed.

Having said that, there are four broad-size categories of the Cockapoo, mainly because of the Poodle parent.

We have the standard Cockapoo, the miniature Cockapoo, the toy, and the teacup.

Each of these size-types gets to its full weight and height after a particular time, and it is good that all potential Cockapoo owners know this.

When is a Cockapoo Full Grown?

It is easy to predict the size a full-grown Cockapoo would be, once you know the parents involved.

In general, the Cockapoo should have gotten full growth at 24 months, which is two years.

That said before the first year the Cockapoo is likely to have a growth spurt, making the owners wonder if it would stop growing.

A 12-month-old Cockapoo is usually at its height and weight peak.

The major determinant of what category the Cockapoo will fall into is the Poodle parent.

The Cocker Spaniel comes in only one size, but it is the Poodle that could be Teacup, Toy, Mini, or Standard.

Whichever one is crossed with a Cocker Spaniel influences the result.

If you want to know which size type you’re getting, ask to see the Poodle parent.

Each category has an expected (but not set) height and weight that qualifies it as full-grown.

When is a Standard Cockapoo Full Grown?

The Standard Cockapoo is the least suitable for an apartment because it is the biggest of all the Cockapoo sizes.

It needs a house with a yard that it can stretch its legs in.

The full height of a Standard Cockapoo usually falls between 15 and 18 inches and it gains a weight of around 19 to 20 pounds.

Due to their bigger size, the Standard Cockapoo takes more time to develop, compared to the other types.

Growing can last for 9 months up to 12 months (a year). After that, expect only muscles or fats.

You can control this by giving a Standard Cockapoo enough exercise and looking out for obesity.

When is a Mini Cockapoo Full Grown?

The Mini Cockapoo is slightly bigger than the Toy Cockapoo and can also fit into an apartment, as well as a bigger house with a yard in it.

It isn’t as big as the Standard Cockapoo, so keeping it in an apartment won’t make for an uncomfortable situation as long as you give it regular exercise. 

The Mini Cockapoo weighs between 13 and 18 pounds and grows up to 14 inches, though some may stop at 11, just an inch taller than the Toy Cockapoo.

This type gets to full size between 6 and 9 months.

When is a Toy Cockapoo Full Grown

The Toy Cockapoo is the smallest size after the Teacup, thus making it adaptable to different environments.

Some experts don’t recognize the Teacup size in many purebred dogs like the Poodle parent, so it won’t be wrong to say the Toy Cockapoo is the smallest standard size.

Having said that, because we’re dealing with mixed breeds, the Teacup has to be acknowledged as existing in its separate category.

Therefore, the Toy Cockapoo precedes the Teacup in size.

When fully grown, the Toy Cockapoo weighs around 12 pounds and grows no more than 10 inches.

It reaches its full growth faster than the Standard Cockapoo because of its smaller size.

Between 7 and 11 months, a Toy Cockapoo is expected to have grown fully.

When is a Teacup Cockapoo Full Grown?

The Teacup Cockapoo is the smallest of all sizes, and the most controversial.

The Teacup Poodle parent that it gets its size from isn’t recognized by the American Kennel Club as a size of its own.

This is due to the unethical methods often employed to get these little pooches.

Teacup dogs are more prone to health issues than any other size, a point you must take into consideration before getting any. 

If you do decide to get one, its height range will be smaller than the Toy Cockapoo, so the Teacup will be somewhere between 6 to 9 inches and weigh up to 6 pounds.

A Quick Guide on Cockapoo Generations

F1 Cockapoo

Besides knowing about the different sizes of this hybrid, you should also understand the generations.

The F1 Cockapoo refers to the 1st generation of the mix.

Every F1 Cockapoo puppy has as parents a purebred Cocker Spaniel and a purebred Poodle.

Both parents are lovely companions, which contributes to the popularity of this designer breed.

The letter ‘F’ isn’t limited to this mixed breed alone but is often used to designate the 1st generation of any breed. It stands for ‘Filial hybrid’, 

1st generation Cockapoos are the hardest to predict because of the many differences in the parents.

Some offspring look like the Cocker Spaniel, others get the physical traits of the Poodle.

If you’re going for an F1 mix, be prepared for anything.

Their personalities are alike, anyways, so with good training, you would get an affectionate household pet. 

F1B Cockapoo

The F1B Cockapoo is like a subset of the 1st generation, except in this case a hybrid is crossed with a purebred to highlight a particular trait.

The ‘B’ in the equation stands for backcross, which is what happens here.

For instance, when a breeder wants to increase the chances of getting a hypoallergenic mix (which is a Poodle’s quality), the breeder will cross an F1 Cockapoo with a purebred Poodle to get an F1B Cockapoo with a dominant Poodle gene. 

Backcrossing can also occur multiple times, resulting in F1BB hybrids.

Also, some breeders may choose to backcross other Cockapoo generations, one of which we’ll be looking into next. 

F2 Cockapoo

The 2nd generation Cockapoo is a mix of two F1 generation hybrids. Here, the breeder will cross two Cockapoos to produce a Cockapoo offspring.

Many assume a designer breed must be gotten from two purebreds. However, such is not always the case.

The F2 generation tends to have a more uniform appearance because the designer breeds crossed have more similar genes than purebred parents.

Is a Cockapoo a small or medium dog?

The Cockapoo comes in different sizes and can be classified into four broad categories.

The Teacup and Toy versions are small, while the Miniature size and the Standard one are both medium-sized dogs.

How big is a full-grown Cockapoo?

The full-grown standard Cockapoo weighs around 19 to 20 pounds and grows up to 18 inches. Other Cockapoo versions are smaller in size.

Final Thoughts

The Cockapoo is one of the most popular designer breeds and can accommodate any living conditions because of the size variations.

The pet owner in need of a medium-sized dog will get one, and so will a small dog lover.

Every figure listed in this guide serves as estimates, not fixed results.

You may find that your case is slightly different from our findings. However, some guidelines apply.

A Teacup and Toy Cockapoo can’t be taller than 10 inches, for example. Thus, this would assist in identifying the size you want amidst the litter.

Don’t forget to ask for the parents as they would help you know more of what to expect from the puppy in your hands.
