When choosing a breed of dog, one of the first considerations is how big they will get. If you are looking at the Yorkipoo (Yorkiepoo) dog breed or have recently got one, then this guide here today will provide you with all of the information that you will need. You’ll also be able to set your expectations, plan ahead and ultimately take better care of your dog.

So, how big do Yorkipoos get? A Yorkipoo will reach 7-15 inches in height and weigh 3 to 14 pounds on average. A Yorkipoo will reach their full adult and mature size by between 8 and 15 months of age. Factors that influence size are their lineage, nutrition, activity levels, whether they are neutered, and age.

A Yorkipoo is a relatively new hybrid that originated in North America in the 1990s. It is a cross between the Yorkshire Terrier and a Toy or Miniature Poodle.

These dogs make excellent pets because of their gentle, affectionate, and fun-loving nature. Yorkipoo’s can live just about anywhere, including smaller homes and apartments.

This breed loves to jump and run fast, but they are equally happily curling up on their owner’s lap.

As they are a mix of two small dog breeds, it is natural to wonder how big they can ultimately get and when you can expect them to do so. We will expand on those factors in the sections to follow.

How Yorkipoos Are Bred

To get a better understanding on the growth potential of a Yorkipoo, it is first important to to consider how they are bred.

Yorkipoo’s, like many other doodle mixes (e.g. Cavapoo, Maltipoo etc) are hybrid dogs. They are the result of breeding two pedigree breeds together.

Interbreeding like this has been done to help produce new breeds of dog that possess the superior traits of the pure breeds, and additionally, to reduce those more undesirable traits, risk factors and health complications that can occur in the parental and pure breeds.

Hybrid breeders do so over generations of dog – and by doing so, are able to better refine the qualities of each new litter. This is essentially how they developed the ‘designer dog’ title.

Generation breeding, as it is known, improves the chances of particular qualities being inherited by the litter. Your Yorkipoo, or the Yorkipoo you are looking at getting, is the result of this process. This is essentially why Yorkipoos can look and differ quite dramatically.

With generational breeding, specific acronyms are used to reference each generation. These are: F1, F1b, F2 etc. You might have seen breeders mention them.

The number relates to the exact generation of the litter, in the lineage of the hybrid breeding.

An F1 generation is typically the most expensive; whereas as you go through the generations (F2, F3 etc), you are more likely to see new traits and they can be ‘designed’ more effectively.

Now why is this all important?

Generation breeding has enabled breeders to manage and manipulate the size, coat style and color of their dogs.

Here is a brief overview of how generational breeding works.

F1: This Yorkipoo is the result of breeding a Yorkshire Terrier and a Toy/Miniature Poodle. So, this dog and the rest of the litter, will be 50% Yorkshire Terrier and 50% Toy/Miniature Poodle.
F1B: This Yorkipoo is the result of breeding an F1 Yorkipoo with a Toy/Miniature Poodle. It will have 75% Toy/Miniature Poodle and 25% Yorkshire Terrier in them.
F2: This Yorkipoo is the result of breeding two F1 Yorkipoos together. Again, this dog and the rest of the litter, will be 50% Yorkshire Terrier and 50% Toy/Miniature Poodle.

So as you can see, breeders are able to engineer the litter in a multitude of ways.

‘Poo’ hybrids, including the Yorkipoo, have become increasingly popular recently as breeding expertise and knowledge has advanced.

While there has been an increase in multi-generational breeding (Yorkipoo to Yorkipoo), and also in Yorkipoo to Poodle or Yorkipoo to Yorkshire Terrier breeding; most litters are first generation, the result of breeding two purebred parents.

How Big Do Yorkipoos Grow?

As you can see from the above, the size of a Yorkipoo, both at birth and once they have reached maturity, is largely reliant on how they are bred.

Since the Yorkipoo is a cross between a Yorkshire terrier and either a Miniature or Toy poodle, they are considered small dogs. However, the size can vary quite dramatically depending on the poodle parent’s size.

The average Yorkshire Terrier is around 4-6 pounds and 8-9″ in height – with little variance in the breed.

However, poodles come in a range of sizes – and in the case of a Yorkipoo, the most commonly used to breed are the Miniature and Toy poodle breeds.

For this reason, Yorkipoos can differ in terms of height and weight.

So, here would be the different size types of Yorkipoos and how they are bred:

Standard Yorkipoo- bred from a Yorkshire Terrier and a Miniature Poodle
Smaller Yorkipoo – bred from a Yorkshire Terrier and a Toy Poodle.

This is ultimately why an adult Yorkipoo can weigh between 3 and 14 pounds. Although the average weight is between 7 to 10 pounds.

The average height is anywhere between 7 to 10 inches.

As a result of breeding a Yorkshire Terrier and a Miniature/Toy Poodle, there are a number of qualities that a Yorkipoo is likely to have.

Active, playful and energetic (like experienced in both Yorkshire Terriers and Poodles),
No/Low-shedder and therefore mostly hypoallergenic,
Loyal, loving and gentile – making them ideal for children and younger families,
Generally does well with other dogs/pets.
Typically easier to train than other breeds,

What Age Is A Yorkipoo Full Grown?

The puppy stage is full of mischief, and many owners wonder when their pup is ever going to become an adult.

Puppies are small and cute but, it is easy to forget that they won’t be that way forever. With your puppy, you can expect significant changes in his size in the weeks and months to follow, but when is a Yorkipoo full grown?

As a mixed breed, it is hard to pinpoint when exactly the Yorkipoo is fully grown.

This is because Yorkipoos can fall into either the small and medium dog breed category.

Small dog breeds usually reach their full weight and height between the ages of 8 and 12 months.
Medium dog breeds tend to reach their full height by the ages of 12 and 15 months – it can take longer to reach their full weight (between 18 and 24 months).

Nobody can say for sure at what age a Yorkipoo stops growing; some dogs may grow faster or slower depending on their ultimate size and lineage.

However, from the above information, we can estimate that a Yorkipoo will be fully grown around 8-15 months.

From an anatomical viewpoint, dogs grow similarly to human children, especially concerning height.

The bones of a dog stop growing once they become adults. The long bones in a puppy’s legs grow from two places called growth plates.

These growth plates are soft and flexible during puppyhood when new tissue is developing.

As the new tissue ages, it calcifies and becomes harder. Once these new tissues are completely calcified, they are closed, meaning that they have ceased growing, and the bone has reached its full size.

It is worth noting that growth plates are fragile and susceptible to injury. You must prevent your puppy from engaging in strenuous and excessive exercise that will damage their growth plates.

You must not allow your puppy to jump from great heights, as this will cause harm to them and can even cause issues with their growth and reaching their full potential.

When you can expect your Yorkipoo to stop behaving like a puppy and start acting like a mature adult dog is another matter.

Some dogs mellow faster than others.

As with humans, dogs have their unique personalities. Generally, you should begin to see a change in behavior, general attitude and temperament. It is at this stage you will begin to observe that they are maturing.

Hopefully, the information above should give you a rough timeline as to when you can expect your puppy to become an adult – both physically and behaviorally.

What Contributes To Yorkipoo Size?

As noted, Yorkipoos are the offspring of Yorkshire terriers and either Toy or Miniature poodles; this has led to a wide variance in the size of the Yorkipoo.

Efforts have been made to achieve a more consistent hybrid by using only toy poodles.

This practice should result in a more regular size and weight limit for this dog breed.

Aside from lineage, we briefly mentioned factors that contribute to Yorkipoo sizes, let’s expand on some of those factors:

Genetic Differences

As with any breed, every Yorkipoo has its genetic code, which can determine the length of their growth period, build, and adult size.

Some traits are passed down to puppies by their parents; others are random variations occurring during DNA recombination.

Nutrition

Puppies need a proper diet to obtain the minerals and protein required to grow into healthy adult canines.

To increase your pup’s potential, feed them a high-quality diet specifically designed for them during this stage of life.

These foods typically have a higher protein content and will provide your puppy with the nutrition their growing body requires.

Spaying And Neutering

Some owners believe that their dog won’t reach their potential adult size and weight if they neuter their pet.

Technically speaking, spaying and neutering can cause very subtle alterations in the growth rate trajectory.

However, studies reveal that the effect is minimal.

Dogs neutered before 16 weeks, typically grow to be a bit bigger than those who are not neutered at this age. Believe it or not, hormones are not the main driver of growth, nutrition and nutrition are.

Finally

How big Yorkipoos get is dependent on a number of factors – some are genetic whereas a few will be in your control and can be slightly influenced.

It is important to note however, that the full adult size of your Yorkipoo is mostly reliant on their ancestry and how they were bred. Was a Miniature or Toy Poodle used in the breeding process? What generation of dog are you looking to adopt?

As you can imagine, if you opt for a Yorkipoo that has been bred from a Toy Poodle – you can expect a smaller dog – both in height and in weight.

Either way, the Yorkipoo breed have amazing personalities and are generally very playful. They are great for families, even those with younger children. Equally, they are quite happy living with elder people and living in smaller apartments.

It is essential that if you are looking at getting a Yorkipoo, you consider their lineage and the breeder you are looking to get your dog from. It is not only size, but the health and well-being of your dog is heavily reliant on how they were born and raised.

Backyard breeders and puppy mills for examples are renowned for unethical breeding practices. The dogs that are bred are more likely to incur health complications later in life – they also routinely fail to reach the average size (height and weight) that this breed should manage.

When getting a dog, while it costs more to buy a dog from a better breeder outright, this is precisely what you should be looking to do. This will ensure your dog has the best start in life, and will ensure that they have been humanely and appropriately brought into this world.

Ultimately, you are going to want to do your research and due diligence ahead of time.

From there, your Yorkipoo will need the highest quality food that you can afford. This will help them to grow to their potential.

Be sure not to overfeed your dog or contribute to them gaining excess weight.

Equally, do not let them climb/jump or overexercise while they are young as this can lead to growth and bone issues
