How Big Do Westiepoos Get?
New dog owners may ask, how big do Westiepoos get? Although this hybrid dog breed is considered a small- to medium-size pet, there can be some variances in full-grown Westiepoo adults.
A typical Westiepoo, also known as a Wee-Poo or Westiedoodle, can measure between 11 and 17 inches tall and weigh from 20 to 35 pounds.
Of course, additional factors will impact the dog’s full-grown height and weight. These contributing elements may result in your Westiepoo being bigger or smaller than the average size.
Let’s take a look at everything that can affect how large this dog will eventually be.
- Its parents
- Recessive genetics
- Breeding practices
- Male or female
- Intact or sterilized animals
One of the most significant factors in a dog’s full-grown size is how big the parents are. This is because puppies receive half of their genetic makeup from each parent. Therefore, estimating a puppy’s growth with similarly sized parents can sometimes be more straightforward.
Alternatively, drastically different-sized parents can produce a litter of pups falling randomly anywhere between the parents’ size ranges. These puppies are more challenging to predict when they are very young.
Westiepoos are the result of breeding a West Highland White Terrier with a Poodle. Although the terrier is typically only one size, some breeders will choose different sizes of Poodles to achieve a more desirable litter.
The West Highland White Terrier Parent
This dog breed is an exceptional pet in a small package. It will average between 10 and 11 inches tall at maturity and weigh between 15 and 20 pounds. Depending on the dog, it could be relatively small or extend to a medium-sized pet.
The Poodle Parent
Because Poodles come in various sizes, some breeders will offer multiple Westipoo choices or tailor their litters to a specific range. Typically, the Poodle parent will fall into these categories:
- Toy Poodle: Will only measure 10 inches or less and weigh 4 to 6 pounds.
- Miniature Poodle: Can grow between 10 and 15 inches and weigh 10 to 15 pounds.
- Standard Poodle: Larger dog measuring 15 inches and more with a weight of 40 to 70 pounds.
Of course, many reputable breeders choose the toy or miniature Poodle when creating a Westiepoo litter. This pairing results in puppies that can be as small as 6 pounds or as large as 16 pounds and measure 10 to 14 inches tall.
Combining smaller Poodles with West Highland White Terriers will provide more miniature puppies than the terrier. This compact size is often more desirable for dog lovers wanting a small breed pet.
Generally, Westiepoo breeders will limit the Poodle genetics to toy or miniature sizes. This way, they help preserve a hybrid that is closer in size to the original purebred Westie.
However, standard Poodles on the lower end of the growth scale can be suitable for breeding with a Westie dog. With this combination, puppies will grow to be larger than a typical West Highland White Terrier since they get much of their size from the Poodle parent.
These larger Westiepoos are less common than the smaller versions. Therefore, if you want a dog on the larger end of the medium-sizing scale, finding a breeder that uses standard Poodles can provide a bigger pet.
Breeding is not an exact science, unfortunately. Even with some excellent bloodlines, there is no guarantee of what a litter will grow to be until after they arrive.
For some breeders, recessive genetics will show up in generational breeding and provide an exceptionally large or small puppy than expected.
Because the Westiepoo is a hybrid dog, breeders have control over breeding practices when choosing parents.
Typically, a first-generation (F1) Westiepoo comes from a purebred Poodle and West Highland White Terrier. This litter can be challenging to estimate size if the parents are vastly different.
In contrast, some breeders will choose first-generation Westiepoos and breed them together. The resulting litter is second-generation (F2) and will have more consistent sizing than F1 puppies. The further a breeder goes into generations; the more precise a puppy’s size will be.
In addition, some breeders may use back-breeding to isolate specific desirable features, like the size. For example, it is common to take an F1 Westiepoo and breed it with a toy Poodle to create an even smaller hybrid Westipoo litter. These puppies will carry the back-breeding designation (F1B).
Male or Female
Many animals will differ in size, depending on their sex, including Westipoos. On average, males will be slightly larger than their female siblings. It won’t be a huge difference and is often only an inch or two and a few pounds, but it can help dog owners gauge their pet’s adult size.
However, this factor is only an estimate since there are instances where a female pup grows larger than males from the same litter.
Intact or Sterilized Animals
There is some controversy about how sterilization surgery can affect a dog’s growth rate. While some individuals believe that sterilizing an animal too soon before it matures can affect its size, making it smaller than expected, this is more apparent in larger dog breeds.
Alternatively, other cases profess that sterilizing an animal can adversely affect its growth rate, causing it to grow larger than average in height and weight.
At What Age Is a Westiepoo Full-Grown?
Because Westiepoos are small to medium-sized dogs, their growth rate will be quicker than that of large-breed dogs. The smaller the puppy is, the faster it reaches maturity.
For example, small dogs under 20 pounds will be at 75% of their fully-grown size by the time they are six months old. In contrast, medium-sized Westiepoos will only reach 66% of their adult size at this identical milestone.
Although it can be confusing to figure out when your Westipoo will stop growing, pet owners of this lovable hybrid breed can expect full-grown Westiepoo adults between 8 and 12 months of age.
Westiepoo Growth Chart
Figuring out how much your Westiepoo will grow and when they will stop is often easier to understand with a growth chart outlining the variances. Although there is technically only one size of Westiepoo, potential dog owners will find them from breeders in various sizes.
You can also use an online dog size calculator to help estimate the possible size your pet will reach in maturity. Pet owners just enter their dog’s age by days, weeks, or months, and its current body weight. This automatic formula will provide an estimated adult size in seconds.
The Westiepoo with a Toy Poodle Parent
This hybrid dog breed will remain on the smaller side when one of its parents belongs to the toy Poodle group. Therefore, it is common for your Westiepoo to reach its full height of 8 to 11 inches by the time it is six months old.
However, your puppy could still be building muscle mass and gaining weight past this six-month mark. On average, a small Westiepoo will put on its final pounds and fill out muscle-wise between six and eight months old.
This way, you can expect your four-legged friend to be fully grown around 9 to 10 months old. This timeline is average for many dog breeds under 20 pounds.
The Westiepoo with a Miniature Poodle Parent
The Westiepoo that includes a miniature Poodle parent will be slightly larger, equating to a longer growing period than smaller versions. This average-sized dog will be full-grown by its first birthday.
Pet owners can expect their larger Westiepoo to reach their tallest height between 9 and 11 months old at 12 to 14 inches. Then, between 11 and 13 months old, these dogs will finish growing by developing muscle mass and gaining the rest of their body weight, helping them round out to between 20 and 35 pounds.
The Westiepoo with a Standard Poodle Parent
Although this breeding combination is not common, it can still be a likely pairing if the Poodle parent measures on the small side of the standard scale.
As a result, the Westiepoo puppies will continue to grow until approximately 12 to 14 months old. After that, this larger variation of this hybrid breed can increase as tall as 15 to 17 inches in adulthood and weigh 40 to 50 pounds.
Is Your Westiepoo Overweight?
Often dogs like the Westipoo are prone to obesity. They can quickly gain weight by receiving lots of treats for good behavior and not exercising enough.
Because many dog owners don’t recognize the exercise needs of their pets, gaining weight is a common problem, especially for smaller breeds like the Westiepoo.
This hybrid breed needs at least 40 minutes of exercise daily. But if you notice your pet zooming around the house for no apparent reason, they still have the energy to burn off.
Unfortunately, without enough exercise, your pup will not burn off the calories it eats, resulting in it quickly becoming overweight.
You should contact your local veterinarian if you have weight concerns about your beloved four-legged friend. This professional can assess your dog’s current health and recommend any necessary diet or exercise changes.
It’s important to keep your pet at a healthy weight to avoid developing other ailments that can shorten its life.
