If you’ve been thinking about adopting a Lhasapoo and have been wondering, how big do Lhasapoos get, you’ve come to the right place. In this Lhasapoo size guide, we’re going to learn about the size and growth patterns of Lhasapoo puppies. In addition, here you’ll find our interactive Lhasapoo size chart and growth calculator to predict your puppy’s full-grown size. Let’s dig in!

Lhasapoo Size Predictions

Understanding the size of your dog is crucial for a variety of reasons. For instance, this helps you determine if your home is suitable for a dog, or how much you’d be having to spend on dog food and other necessities. 

Before trying to figure out how big do Lhasapoos get, we must first understand the sizes of the parent breeds. The Lhasapoo is a fairly new hybrid cross between the Lhasa Apso and Poodle. Lhasa Apso is a small sized breed with a height of up to 11 inches. Typically, they weigh around 12 to 18 pounds. 

Usually, small sized breeds like Lhasa Apso are almost always crossed with Miniature or Toy Poodles for the sake of the puppies’ health. As a result, we will get the cutest little hybrid like the Lhasapoo. 

Let’s have a look at the average Lhasapoo size predictions:

Weight10-20 pounds
Height9-13 inches
When Full-Grown?8-12 months
* A dog’s height is measured from the highest part of their shoulder blades a.k.a the withers. 

Of course, as with any other hybrid breed, we can’t exactly predict a puppy’s full-grown size. However, if you’ve chosen to adopt your Lhasapoo puppy from a breeder, they should be able to tell you more about how big the parents are, and how big are the puppies in each litter.

In addition, some other key factors that can contribute to your puppy’s adult size is their gender, diet, or how much they exercise. Keep in mind that puppies have different energy and nutrient requirements than adult or senior dogs. 

We recommend you feed them specially formulated puppy food until they reach adulthood, as these formulas usually contain additional vitamins, minerals and supplements to support proper growth and development. For a Lhasapoo puppy, look for dog food specially formulated for small sized breeds. 

For all Doodle owners, we have created some useful guides on choosing the best food for puppies and adult dogs. Make sure to check them out, as your puppy’s diet can make a huge difference in their health and wellbeing.

Are There Different Sizes Of Lhasapoo?

As we briefly mentioned above, Lhasapoos are typically a mix of Lhasa Apso and either Miniature or Toy Poodle. Most commonly, Mini Poodles are used in the mix. The Lhasapoo isn’t categorized in different sizes, but the Poodle parent’s size can, of course, affect the puppy’s height and weight. 

Indeed, if a Lhasa Apso and a Toy Poodle are crossed, we can expect to end up with a smaller sized Lhasapoo. Similarly, a mix of Lhasa Apso and Miniature Poodle will most likely fall on the larger end of the scale. 

Additionally, there can be slight variation between female and male Lhasapoos. Like many other breeds, males tend to run a bit larger than the female pups. The difference is usually only a few pounds in weight and an inch or two in height.  

Lhasapoo Generations

A Lhasapoo’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 Lhasapoo generations and what each of them means:

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

Lhasapoo Size Charts & Growth Patterns

As with most other small Doodles, Lhasapoos usually grow fastest in their first 4 to 5 months. By that time, they’ve often reached half their adult weight and most of their adult height. After that, their growth will slow down a bit. Shortly after, they will reach their full height. However, they will continue to gain weight at a slower pace, and fill out for a couple of more months. Depending on your Lhasapoo’s size, you can expect them to finish growing around 8 to 12 months old.

How Big Do Lhasapoos Get?

Lhasapoo is a small hybrid cross between the Lhasa Apso and Poodle. They weigh between 10 to 20 pounds, and typically stand at 9 to 13 inches tall at the shoulder. Lhasapoos full-grown size can be determined by their gender, genetic makeup, diet, and how much they exercise. Generally, Lhasapoo puppies will reach their full-grown size around 8 to 12 months old.

To conclude, the Lhasapoo is a wonderful companion if you’re looking for a pup who absolutely adores you, loves you, and never wants to leave your side. They’re playful and intelligent, and can thrive perfectly even in a smaller apartment.
