How Big Do Morkie Poos Get? [Average Size Guide For Owners]

Considering the Morkie Poo? I don’t blame you. They are adorable, especially as puppies. But what you will want to know is how big they get. Besides, it’s one thing having a cute, lap-sized puppy yet another having a large, romping dog shortly after. Is this generally the case with the breed? I spent some time researching, collecting, and analyzing the data to find out.

So, how big do Morkie Poos get? Morkie Poos are classified as small dogs, generally reaching between 7-12″ in height and weighing between 5-12 pounds when fully grown, on average. The size of the Poodle used in breeding will ultimately dictate their overall size, with Morkie Poos bred from Toy Poodles being typically smaller.

Morkie Poo Size

This is not a large dog by a long shot.

In fact, while they certainly do grow and go through several growth spurts (as we will soon discuss), they do not stray too far from their puppy size.

At least compared to other breeds.

Let us now take a closer look at their typical size and all other aspects of growth, so you know exactly what to mentally prepare for should you proceed with adoption!

What Is The Average Size Of A Morkie Poo?

The average size of a Morkie Poo is mostly reliant on the parental dogs used during breeding. 

Every breed typically has a size range that they fall within.

For most breeds, it’s mostly down to genetics and the line of dogs in which they come from.

While this is also true for the Morkie Poo, it’s a little bit more complicated.


Because they essentially come from two different lines of dogs. 

They are a hybrid ‘mix,’ after all.

A Morkie Poo is the result of breeding a Maltese with a Poodle.

Now, the Maltese breed has a pretty standard, small size (8-10″ in height, and around 7 lbs in weight).

Poodles, on the other hand, can vary quite dramatically.

There are essentially four different size classifications of them:

  • Teacup poodles – 6-8″ in height between 2-5 pounds in weight,
  • Toy – 9-11″ in height between 6-9 pounds in weight,
  • Miniature – 11-13″ in height and around 13 pounds in weight,
  • Standard – 17-23″ in height between 45-70 pounds in weight,

So as you can see, Poodles vary quite dramatically.

And depending on which one of them is used in breeding with the Maltese, it will largely impact the overall size of the Morkie Poo.

That being said, for the most part, only a miniature and toy poodle will ever be used.

Standard poodles are generally too big for mating naturally with Maltese (who are actually a very small dog in themselves).

While artificial insemination may be used, this is rarely done, and instead, toy and miniature poodles are commonly the sizes of choice.

Even then, there is still variance in the expected final size of the Morkie Poo:

  • Morkie Poos bred from Toy Poodle will generally be around 7-9″ in height, weighing between 4 – 7 pounds, on average.
  • Morkie Poos bred from Miniature Poodles will generally be around 10-12″ in height, weighing between 9-12 pounds, on average.

At What Age Is A Morkie Poo Fully Grown?

Morkie Poos will typically reach their full-grown adult size between the ages of 8-10 months.

And despite being a small dog at full-grown size, they’ll grow quite a bit from the time that you bring your puppy home (typically around 8 weeks of age).

Besides, these dogs are around 0.25 pounds when they are born!

They grow very quickly in the first few weeks of life, literally doubling in size by the end of week 2/3.

And from there, their quick growth rate continues.

In fact, this hybrid breed is known to gain around 1/2 an ounce per day up until the time they are available for adoption.

And here’s a good tip.

A good estimate of the final size of a Morkie Poo can be calculated at around the 8 weeks of age mark.

Simply take their weight, and multiply it by four.

Equally, and a little bit later down the line, you can take your puppy’s weight at 4 months and multiply that by two.

Nevertheless, here is a quick visual guide to give you a rough idea of what to expect:

Size Considerations For Owners

Knowing that a Morkie Poo is, and will remain, quite a small dog, there are a number of important considerations that you should take into account.

First and foremost is safety.

It is essential that you know the exact whereabouts of your Morkie Poo at all times.

These dogs are energetic and love being around people.

And as such, it is essential that you keep them safe whenever you are or are not around.

For instance, you need to ensure you do not accidentally sit on them, kick them or otherwise harm them.

They’re small and fragile, after all.

And taking this one step further, you must be very careful when holding them.

Particularly when they are still puppies.

Dropping them, holding them too tightly; are such things that can cause harm and injury.

Sounds obvious, but it’s easily done.

At the same time, it’s essential not to over-exercise these dogs.

While they are certainly energetic – they do not need much physical exercise.

In fact, a short walk of around 20-30 minutes daily should suffice.

It should not be too strenuous, especially when a Morkie Poo is still a puppy and still young.

Generally, it is advised to provide exercise in relation to their size/age.

A good rule of thumb is a ratio of five minutes of exercise per month of age.

Be sure that it’s at a safe and appropriate pace, nor is it too strenuous to harm or damage your Morkie Poo’s growing joints.

And then there is diet.

As small dogs, it’s essential that these dogs eat little and often.

The smaller Morkie Poos, in particular, struggle with not eating often – and some are known to suffer from hypoglycemia if they go too long without food.

A good approach is to discuss the diet with your breeder. Find out what your Morkie Poo was fed soon after they were born and the foods they have eaten so far.

From there, switch foods gradually, and monitor your dog to see how they respond.

Picking high-quality commercial food is a must, preferably one that is designed for smaller breeds.

Choose one without fillers, additives and ensure it is high-protein too.

 This will ensure your Morkie Poo has the building blocks required for growth and muscle maintenance.

Avoid treating your Morkie Poo too often, and keep junk foods away from your dog as much as possible!

Food should always be fed in accordance with a dog’s age and size – check the packaging for some guidance, and be sure to contact your vet and discuss dietary needs and requirements with them too.


Morkie Poos are a terrific breed; cute, non-shedding, and sweet in temperament.

While they can range in size, these dogs are never usually bigger than 12″ in height and 12″ in weight.

A lot of that has to do with genetics and the fact that they are the result of breeding the small Maltese with the smaller versions of the Poodle.

As such, these dogs are an ideal breed for those who live in smaller spaces, such as apartments, and those who have young children and are not looking for an intimidating dog.

Plus, they do not need too much exercise; they are intelligent and have a keen desire to please their owners.

What more could you ask for.

But if you are still interested in getting a Morkie Poo, be sure to do your research and due diligence.

It’s essential that you purchase a Morkie Poo from a reputable breeder.

Otherwise, your dog could have inherited, or be susceptible to, a range of health issues and disorders.

It’s disheartening and tragic.

And it needn’t be the case.

Thankfully it can be avoided so long as you are mindful.

Do not let this put you off.

They’re a terrific tiny breed, after all.
