A Yorkie Poo is a hybrid breed that comes from mixing a Toy or Miniature Poodle with a Yorkshire Terrier. They are popular because of their small size, friendly personalities, and loyalty. While their small size is a big selling point, exact sizes can vary. It’s still important to know that Yorkie Poos grow at different rates and have different needs depending on their size and age.
In this guide, we’ll cover what a Yorkie Poo looks like when it is fully grown and how its size and age may differ. Keep reading to learn more!
What Is a Yorkie Poo?
A Yorkie Poo is a cross between a Yorkshire Terrier and a Poodle. The breed was first introduced in the 1970s when dog breeding first became popular. Since then, the Yorkie Poo has grown in popularity ever thanks to its good looks, hypoallergenic coat, and small size. On average, a Yorkie Poo weighs between five and 14 pounds (2–6 kg) and reaches seven to 15 inches (18–38 cm) in length.
The Breeding Process for Yorkie Poos
To understand the size and weight growth potential of Yorkie Poos, you first need to understand their breeding process. A first-generation Yorkie Poo is the child of a Yorkshire Terrier and a Toy Poodle. The result is a hybrid puppy that contains some of the best characteristics of each pet.
Yorkie Poos vary in length and weight depending on whether they’re F1, F1b, or F2 generations. Here’s a quick breakdown of the difference between these:
- An F1 Yorkie Poo’s parents are a Yorkshire Terrier and a Poodle. They are considered the “purest” and most expensive Yorkie Poo.
- An F2 generation’s parents are two F1 Yorkie Poos.
- An F1b Yorkie Poo’s parents are an F1 Yorkie Poo and a Yorkshire Terrier.
Yorkie Poo Maturity Stages
A Yorkie Poo has three different maturity stages. Each one has different heights, weights, and lengths.
This stage lasts from birth until around six months old. Your puppy will weigh around 3 pounds at birth and grow up to 8 pounds by the end of this stage.
The adolescent stage begins at six months old and lasts until about one year. During this time, your puppy’s ears will stand up straight, and he will walk more confidently on all four legs instead of wobbling around. Your puppy will weigh between 12-15 pounds by the end of this stage.
After the first year, your adult Yorkie Poo will be fully grown! Adult Yorkie Poos weigh about 15 pounds.

How Big Do Yorkie Poos Get?
Yorkie Poos can be anywhere from 28 to 38 cm long and weigh an average of 15 lbs. A Yorkie Poo’s growth depends on genetics, breed type, nutrition, and environment.
Full Grown Yorkie Poo
If you’re considering getting a Yorkie Poo puppy, you may wonder about its fully grown size before committing to it as part of your family. The average full-grown Yorkie Poo weighs 15 pounds (6.8 kg) and is about 15 inches (381 mm) long.
Is a Yorkie Poo Bigger Than a Yorkie?
There are some significant differences between Yorkie Poos and their parent breeds, the Yorkie and Poodle. Most notably, Yorkie Poos tend to be a bit larger than purebred Yorkshire Terriers in terms of height and weight—but not by much!
Yorkie Poos grow anywhere from seven pounds to 15 pounds and are around 15 inches tall, but Yorkies only grow to be 4 to 7 pounds and 7 to 8 inches tall.
What Does a Full-Grown Yorkie Poo Look Like?
Some Yorkie Poos have longer bodies than others, while others will remain more compact throughout their lives. Many Yorkie Poos’ coats are long and silky and possibly even curly. But some may also have shorter hair or fur that is less fluffy than their relatives.
How Much Does a Full-Grown Yorkie Poo Weigh?
The average weight of a full-grown Yorkie Poo is 15 pounds. If you have a Yorkie Poo, you should try to weigh him at least once per month and even more frequently if he is overweight.
If your pooch needs to shed a few pounds, frequent weighing gives you an accurate idea of how much progress he’s made over time. When he gets into adulthood, you’ll have confidence knowing that his size is normal.
Normal Yorkie Poo Length
As you may have already guessed, Yorkie Poos are small dogs. They’re seven to 15 inches long and only weigh around 15 pounds. For this reason, many people often confuse them with teacup dogs, but they’re not!
What Factors Influence Yorkie Poo Weight and Length?
Some of the factors that will affect your puppy’s weight and length include the following.
When predicting how much your Yorkie Poo will weigh, it’s essential to understand its genetic makeup. The first step is determining if your puppy has any purebred parents or grandparents and what their genetic makeup was.
Like most dogs, Yorkie Poos have a gene that affects their weight. The gene is called the IGF-1 (Insulin-like Growth Factor 1) gene, and it’s responsible for growth.
Weight genes also pass from the parents to the puppy, so if your dog has a longer Yorkie parent, it will probably be taller than average. The same goes for those with short Yorkie Poo parents—they’re more likely to be smaller than their peers.
A healthy diet is vital to helping your Yorkie Poo grow to its full potential. If you’re concerned about your Yorkie Poo puppy’s weight, it’s best to research how much food they should be eating.
A good rule of thumb is to feed your pup (or pups) high-quality dog food made from formulas specifically designed for small dogs with unique nutritional needs.
Neutering or spaying a dog can have some positive health benefits. The surgery prevents unwanted pregnancies in female dogs, protecting them from pregnancy-related diseases. Neutered male dogs also have a lower risk of getting certain cancers, such as prostate and testicular cancer.
However, neutering a male dog can make him grow taller. The reason is that neutering reduces the levels of hormones, which in turn stops growth plates from closing completely. This means your dog will keep growing until he reaches maturity, which is usually around two years old for Yorkies and Poodles.
The same principle applies to females as well. However, since they don’t have testicles to lose with neutering, this phenomenon doesn’t affect them quite as much as males. Yet it’s still possible that having their ovaries removed could impact their growth rates.
If you notice your Yorkie Poo is eating and drinking but not gaining weight or growing, it’s time to take action. Your vet can diagnose whether there is a problem with your Yorkie Poo’s health.
Hypothyroidism is the most common health problem that affects weight and length in a Yorkie Poo. Hypothyroidism is when the thyroid gland does not produce enough hormones for the body to function correctly.
Hypothyroidism can affect metabolism, making it harder for you to manage your weight. This condition can affect any dog breed but is commonly found in smaller breeds like Yorkie Poos due to their size.
Pregnant Yorkie Poos are not very different from other dogs during their pregnancy. The only difference is that they will have a bigger belly because they are so small. Pregnancy will cause their body to expand to accommodate the growing baby.
The following is an approximate weight gain during pregnancy:
- First trimester: 1-2 pounds
- Second trimester: 3-4 pounds
- Third trimester: 5+ pounds
During pregnancy, your Yorkie Poo will need more food than usual to support her growing puppies. A high-quality puppy food formulated for pregnant dogs is recommended during this time.
A Yorkie Poo’s gender is also crucial when determining if it’s fully grown. Male Yorkies tend to be larger than female Yorkies. They also typically have a broader head and muzzle. On the other hand, females are often shorter than their male counterparts.
Tips For Feeding Your Yorkie Poo for Optimal Growth
A Yorkie Poo is a small dog with a small appetite. It’s essential to feed your Yorkie Poo the right amount of food, but not too much since they can be picky eaters and prone to obesity.
When choosing dog food for your Yorkie Poo, you should stick with high-quality kibble explicitly designed for small dog breeds like the Yorkie Poo.
Look for something that contains fewer calories, fats, and carbohydrates than regular dog food and is rich in protein sources such as chicken, lamb, or fish, which will help them grow strong bones and muscles without getting fat.
Do Yorkie Poos Stay Small?
Yorkie Poos won’t grow too large in height and weight, but they certainly will be bigger than they were as a puppy. Still, they’re small dogs – just not small enough to carry around in your purse!
Yorkie Poos grow slowly as puppies because their bones take longer to harden than other dogs. They also tend to gain weight easily if they are overfed or eat too many treats.
It’s important not to spoil a Yorkie Poo puppy. During this stage of life, they can easily become overweight, leading to health problems such as joint issues or diabetes down the line.
