In this Westiepoo size guide, we’ll be covering everything you should know about the size and growth patterns of a Westiepoo pup. We’ve also created an interactive Westiepoo size chart and growth calculator, which you will find in this article. Let’s get started!

Westiepoo Size Predictions

Westiepoo is an adorable cross between the West Highland White Terrier and Poodle. Sometimes also called a Westiedoodle or Wee-Poo, this little pup is the perfect furry little friend for almost anyone.

Westiepoos have inherited high intelligence levels and a bubbly personality from the parent breeds. But what about Westiepoo’s size? How big does a Westiepoo get? Luckily, we don’t have to look far, as Westiepoos parent pups can give us some pretty good hints about that.

The West Highland White Terrier is a small sized breed who weighs between 15 to 20 pounds, and stands at 10 to 11 inches tall at the shoulder. As you might know, Poodles come in three sizes – Toy, Miniature, and Standard. Therefore, as the West Highland White Terrier is a small dog, they are usually crossed with either Toy or Miniature Poodles. 

But how big does a Westiepoo get? Like with other hybrid breeds, it’s difficult to predict with 100% accuracy how big a Doodle puppy will get. They can take after either of the parent pups in terms of size, looks, and personality. Additionally, your Westiepoo’s size is determined by their genetic makeup, gender, diet, and exercise levels. 

It’s important we highlight that all Doodle puppies should be fed specially formulated puppy food for their proper growth and development. This helps to reduce the risk of any health issues later on in life, but also supports those growing little babies who need all the energy and nutrients to grow into healthy adults.

Are There Different Sizes Of Westiepoo?

Although technically the Westiepoo comes in ‘one size’, it can vary because of the Poodle parent. If a Westie is crossed with a Toy Poodle, you can expect to end up with a smaller pup than a Westiepoo who has a Miniature Poodle parent. Although crossing a Westie with a Standard Poodle is not unheard of, it’s rarely done. 

Here are the average Westiepoo size predictions:

Mini Westiepoo
Weight10-20 pounds
Height10-15 inches
When Full-Grown?8-12 months
*A dog’s height is measured from their withers, which is the highest part of their shoulder blades.

Furthermore, like all other dogs, male Westiepoos can be slightly larger than females. However, the difference is usually just a few inches in height and a few pounds in weight. Not a big difference, but definitely something to keep in mind!

Westiepoo Generations

A Westiepoo’s full-grown size is also determined by their generation. What does this mean exactly? Well, as we are combining two different purebred dogs, the generations are a great guideline that show us how much of the puppy’s genetic makeup consists of either of the parent breeds. 

Let’s take a quick look at the Westiepoo generations and what each of them means:

With each generation, we can achieve more control over a Westiepoo’s size and other characteristics, such as their coat type and appearance.

Westiepoo Size Charts & Growth Patterns

Like most other dogs, Westiepoos will experience the most rapid growth stages in their first 50% of adult weight. By that time, they’ve also reached the bigger portion of their adult height. After that, their growth will gradually slow down over the upcoming months. 

Tiny Doodles like Westiepoo usually reach their adult height around the time they’re 6 to 9 months old. However, they will continue to fill out and gain some weight at a much slower pace. Based on the observed growth patterns, we can expect a Westiepoo puppy to reach half their adult weight around 3 to 4 months old. Around 8 to 12 months, your Westiepoo will most likely finish growing. 

To take some work off your hands, we’ve created an interactive Westiepoo size chart and puppy growth calculator. To predict your Westiepoo’s full-grown size, just enter your Doodle’s type, predicted size, weight, age in weeks, and you’re ready to go!

You can also use this formula to calculate your Westiepoo’s estimated adult weight:

How Big Do Westiepoos Get?

As the West Highland White Terrier is a small sized breed, they are usually crossed with either Toy or Mini Poodles. The average full-grown Westiepoo size is usually between 10 to 20 pounds in weight, and they stand at 10 to 15 inches tall at the shoulder. Typically, Westiepoos reach their full-grown size around 8 to 12 months old. Smaller pups will most likely finish growing a bit sooner than larger Westiepoos. 

Keep in mind that as Westiepoo is a hybrid breed dog, we can never know exactly what we might end up with. Some puppies are just naturally larger, some smaller. If you choose to adopt a puppy from a responsible breeder, they will be able to tell you more about the parent dogs, and the average size of puppies in a litter.

If you’re worried about your Westiepoo’s size and weight, be sure to consult with your veterinarian. 

In conclusion, the Westiepoo is an adorable little goofball who loves playtime and spending time with their family. They’re easy to train thanks to the highly intelligent parent pups, and can live comfortable even in an apartment. If you’ve decided to bring home a Westiepoo puppy, you might find our Westiepoo size chart and weight calculator a handy tool for tracking their weight into adulthood.

We hope this Westiepoo size guide has been a useful resource in understanding the size and growth patterns of this charming little furball.
